It would be awesome to modify spark to print narrow characters in for example Gnome Terminal. Is this at all possible with Bash / Python?
|
No. While VT100-compatible terminals do have support for double-width lines (using the DECDWL control sequence), they don't have support for narrow lines or characters.

I am having a little problem with my ubuntu16.04 terminal.
I wanted to have access to a data-base through the use of the :
echo source /Infos/bd/config11 >> .bashrc
echo source /Infos/bd/config11 >> .bash_profile
However I unfortunately don't have acces to this data-base since it's not on my computer.
Every time I open a terminal I see:
bash: /Infos/bd/config11: No such file or directory
What can I do to stop seeing this on my terminal?
Thank you.
|
To avoid seeing this, you should edit your startup scripts so they no longer attempt to source the missing file:
sed -i 'sXsource /Infos/bd/config11X#&X' ~/.bashrc ~/.bash_profile
This will comment out the line in both files.

I'm using Gnome Terminal to connect via SSH to my server. My account on the remote server (which is Ubuntu) uses bash. My bashrc contains a line that sets the shell prompt to include my current git branch if applicable:
parse_git_branch() {
git branch 2> /dev/null | sed -e '/^[^*]/d' -e 's/* \(.*\)/ (\1)/'
}
export PS1="\u@\h: \[\033[32m\]\w\[\033[00m\]\$(parse_git_branch)\$ "
When I am inside a git repo, my terminal stops wrapping properly. Long commands that should wrap onto the second line instead wrap to the beginning of the line they started on and start printing right on top of my prompt.
I don't experience wrapping issues except when my working directory is inside a git repo (i.e., when parse_git_branch's output is not empty).
I know that non-printable characters should be enclosed in \[ and \] so that the shell (or terminal?) knows not to count them towards the length of the prompt. I'm fairly confident that the "export" line has correctly done that... but my regex-fu is not strong enough to understand what that sed command is doing, and I think it isn't inserting the non-printable characters properly.
This question is extremely similar (and even uses the same parse_git_branch function, which we got from here), but the other question involved having an emoji in the prompt, which is not the case for me.
Does anyone know what is wrong with my prompt?
|
This turned out to be because I had enabled the ui color=always option in git, not directly because of my shell prompt or the parse_git_branch function. The "git branch" command was displaying with color, but the original author of the parse_git_branch function did not account for that and chopped the string up in such a way that the color codes didn't get closed properly.
Adding the --no-color flag to the "git branch" command inside of the parse_git_branch function was enough to fix the issue, but I had actually grown accustomed to the colors -- so here is how to replicate the gold background:
parse_git_branch() {
git branch --no-color 2> /dev/null | sed -e '/^[^*]/d' -e 's/* \(.*\)/ (\1)/'
}
export PS1="\u@\h: \[\033[32m\]\w\[\033[00m\]\[\033[7m\033[33m\]\$(parse_git_branch)\[\033[00m\]$ "

I was running Fedora 34 until now. Fedora 38 came out and I moved to that. I'm using MATE with Gnome Terminal. The font is set to Monospace 13 in both systems. Yet there's a difference in the font. What I don't like in Fedora 38. How could I have the same font like I had in Fedora 34? The change can be seen especially on "r"
|
"Monospace" is not a real font; it's merely an alias to some or other font, which traditionally used to be DejaVu Sans Mono on Linux for about a decade – with the distinct flattened @ shape as in your "original" screenshot.
(DejaVu fonts weren't really great fonts though, merely decent, but for a long time there weren't any better FOSS fonts available, especially for a distro such as Fedora that was strongly concerned with licensing. However, now that more free fonts exist, it is not surprising that Fedora has changed the default.)
If you run fc-match Monospace you will see the current mapping.
How could I have the same font like I had in Fedora 34?
First, install the fonts. Fedora no longer includes DejaVu by default, so install dejavu-sans-fonts via DNF (or download them from GitHub into your ~/.local/share/fonts/).
Once installed, just change the terminal font through GNOME Terminal's "Profiles > Default".
Changing font aliases system-wide
Within GNOME, the org.gnome.desktop.interface monospace-font-name GSetting might be the one that controls the alias system-wide (although of course you can just change it for the terminal alone; it's fine to use one monospace font for terminals and another for normal text).
GNOME Tweaks > Fonts > Monospace Text
regedit: dconf-editor > /org/gnome/desktop/interface/monospace-font-name
gsettings set org.gnome.desktop.interface monospace-font-name "Something 11"
Outside of GNOME, such aliases are defined via Fontconfig (e.g. /etc/fonts/conf.d). For example, create a ~/.config/fontconfig/fonts.conf that contains:
<?xml version="1.0"?>
<!DOCTYPE fontconfig SYSTEM "urn:fontconfig:fonts.dtd">
<fontconfig>
<alias>
<family>Monospace</family>
<prefer>
<family>DejaVu Something Or Other</family>
</prefer>
</alias>
</fontconfig>
as documented in man fonts.conf.

I often need to grep for a particular expression in a large text file. For some reason the private vendor decide to use CR (carriage return, \0D) to separate argument on a particular line of the text file.
However the CR character gets interpreted by the terminal, making my grep or cat command pretty much useless.
So how would one display the content on the following file on a terminal (eg. xterm-256color).
$ hexdump /tmp/bla
0000000 3031 3030 3020 0d20 3335 310d 3132 3830
0000010 300d 302e 3031 3030 0d30 0a33
000001c
So far I tried without much luck:
$ TERM=dumb cat /tmp/bla
3.010000
|
GNU cat has a few options to aid printing files containing such special characters:
-v, --show-nonprinting
use ^ and M- notation, except for LFD and TAB
So cat -v /tmp/bla should do it in your case. Or perhaps even -et, which also prints tabs and line ends in a special way.

I've recently installed Linux Mint 18.1 and I'm using Terminal all the time. My Terminal is GNOME version 3.18.3.
There are various menus in the GNOME Terminal. In Windows you typically access something like "Edit" by going Alt-E. This doesn't work for Terminal. Is there any way of of accessing these menus without being forced to use the mouse?
|
In GNOME Terminal, you can access the menu using F10. Press that to open the File menu, then use the arrow keys to navigate inside that menu (↑ and ↓) or to open other menus (← and →).
You can enable menu shortcuts (AltF for the File menu etc.) by checking the “Enable mnemonics” option in the preferences:
You can also disable the F10 shortcut here.

I am using Arch linux. However after the recent gnome update, I am not able to copy or paste anything into or from gnome terminal to gui applications like editors or browsers. However I am able to copy and paste within the the terminal like coping and pasting a previous command or output. I am also able to copy paste within GUI applications, for example between an editor and a browser. How ever I am not able to copy paste from the browser to the terminal or from the editor to the terminal and viceversa.
I am sure this is not a keyboard shortcuts issue as Ctrl+ C, Ctrl+ V,Ctrl+ Shift +C, Ctrl+ Shift + V as expected when used within the terminal or among the GUI applications.
I have tried installing clipit, but there is no difference. I am pretty sure I didnt have the issue before.

My gnome-terminal on a ubuntu 10.10 machine is not working the way it should work. No autocomplete is working. ctrl + l won't clear the screen, bash prompt is simply a $ and nothing else. I got this machine passed on from someone else. I just created a new user for myself and hoped that I would get a fresh start.
I checked and there is no /etc/profile or /etc/bashrc. There was a folder named .profile.d that I renamed to something else. Stil the problem persists.
There are no configuration files inside my home directory either (.bashrc, .bash_profile, .bash_aliases)

make sure that you are indeed running bash and not another csh for example by executing the following:

This will tell you what shell you are running.
If this returns something different than bash you can try your shortcuts after running the following:

I installed konsole and uninstalled gnome-terminal by doing:
sudo apt install -y konsole
sudo apt-get purge --auto-remove gnome-terminal
And then tried:
sudo update-alternatives --config x-terminal-emulator
To set konsole as the default emulator, wich returns:
There is only one alternative in link group x-terminal-emulator (providing /usr/bin/x-terminal-emulator): /usr/bin/konsole
Nothing to configure.
But neither the default Ctrl + Alt + t shortcut works nor do right click open terminal.

I am writing a bash script where I pretend to open a new terminal window (in this case a gnome-terminal), execute some commands and change the title of the terminal window.
In order to change the title of the terminal window I am using the function set-title as proposed in this answer. The approach works perfectly when I open manually a new terminal and type inside the terminal set-title MY_TITLE. But in this case, from within a bash script it is not working even if I source the .bashrc file.
#!/bin/bash
gnome-terminal -- /bin/bash -c "echo Hello from terminal 1; set-title Terminal 1; exec /bin/bash";
gnome-terminal -- /bin/bash -c "source ~/.bashrc; echo Hello from terminal 2; set-title Terminal 2; exec /bin/bash";
The two new opened terminals show the same error:
/bin/bash: set-title: command not found
It is obvious that the bash interpreter does not find the function set-title, but I do not know how to force the loading of the .bashrc file when the gnome-terminal is opened.
|
I will answer my own question but before explaining the two solutions I have found, I will explain why what I was trying to do did not worked.
Why my initial approach was wrong
If you have custom functions in your ~/.bashrc file, like in my case the one for setting the title of the terminal window, those functions will not be available in a terminal window that is opened from a bash script that executes commands in an automated way (as in the example of my question).
Thanks user414777 for the hint. You were absolute right. My ~/.bashrc file contains the following code at the beginning:
# If not running interactively, don't do anything
case $- in
*i*) ;;
*) return;;
esac
By printing the option flags $- the result is hB (as expected is not an interactive shell), so obviously the set-title function that I have at the end of the ~/.bashrc, will never be added to the shell.
Solution 1 (Recommended): Using xfce4-terminal
As schrodigerscatcuriosity suggested, this is the easiest solution for the problem. You might not like to install another terminal tool; if (like in my case) you are using Gnome and you use by default gnome-terminal, but the good side is that you can use the xfce4-terminal for the bash scripts and the gnome-terminal for your "human" interaction, so besides the titles you also have an extra level of categorization (in case you have many terminal windows opened).
The xfce4-terminal works a bit different than the gnome-terminal from within a bash script, but nothing you can not really figure out. In any case you can find below the solution with xfce4-terminal:
#!/bin/bash
xfce4-terminal --title "Terminal 1" -e "bash -c 'echo Hello from terminal 1; exec /bin/bash'" &
xfce4-terminal --title "Terminal 2" -e "bash -c 'echo Hello from terminal 2; exec /bin/bash'" &
Solution 2: Using xdotool
Another solution that I found to the problem is using xdotool. xdotool is a command line tool that can simulate/automate human interaction in the X11 window system.
This solution is overengineering the initial problem since it creates other issues such as the synchronization between the bash script and the X windows system, therefore it is necessary to introduce sleep commands in the bash script to give time to the X window manager to process the events. This synchronization issues make this solution not reliable since it does not works in 100% of the cases and the sleeping times need to be adapted to the speed of the window system.
Despite I do not recommend to go for this solution for the exposed problem in the question, I decided to introduce the solution in the answer for the shake completeness. Someone else might find it useful to apply this approach for some other purpose:
#!/bin/bash
function set-title(){
sleep 0.2
# local WINDOW_ID=`xdotool getactivewindow`
# local P_ID=`xdotool getactivewindow getwindowpid`
# echo "the window id is: $WINDOW_ID with PID: $P_ID"
xdotool type "set-title $@"
xdotool key KP_Enter
sleep 0.2
}
gnome-terminal -- /bin/bash -c "echo Hello from terminal 1;echo $-; exec /bin/bash";
# xdotool search --onlyvisible --class 'gnome-terminal'
set-title "Terminal 1"
gnome-terminal -- /bin/bash -c "echo Hello from terminal 2; exec /bin/bash";
# xdotool search --onlyvisible --class 'gnome-terminal'
set-title "Terminal 2"
In this case, the function set-title included in the ~/.bashrc file will work because after the commands have been executed in the gnome-terminal, the last instruction is /bin/bash. It loads the shell again and the next commands are forwarded to the terminal using xdotool, which creates the same events that a human would generate with the input devices (mouse, keyboard, etc ...).

Problem
I coincidentally was trying to print a string to STDOUT in gnome-terminal that contains a lot of square brackets and noticed it took a lot of IO time (~4sec for ~100KB). To confirm that there is something specific about that string, I printed another string of the length, and the time is very different.
Specifically:
$ time cat file1
# ... snip ...
real 0m3.968s
user 0m0.004s
sys 0m0.001s
$ time cat file2
# ... snip ...

user 0m0.006s
sys 0m0.001s

file1: https://pastebin.pl/view/raw/060c3b2d
file2: https://pastebin.pl/view/raw/ffbdd6a4
I cannot tell what is the cause of the slowdown, I suspect something in gnome-terminal parses square brackets and gives them a special meaning. Does anyone have any idea?
Version Information

Egmont reported the bug on the vte bug tracker (vte is a terminal emulator library used by gnome-terminal, anjuta, deepin-terminal, gtkterm, lilyterm, lxterminal, mate-terminal, remmina, sakura, tilda, vinagre, xfce4-terminal, …). It turned out to be a bug in the underlying fribidi library, which is unfixed as of October 2021.
Workaround: disable bidirectional support
Egmont also suggests a workaround which is to disable bidirectional support. Obviously, that workaround only helps if you don't care about bidi support.
For Gnome-terminal, you can do it via a hidden setting which has to be applied to each profile. The following command does this permanently for your account:
for p in $(dconf list /org/gnome/terminal/legacy/profiles:/); do dconf write /org/gnome/terminal/legacy/profiles:/${p%/}/enable-bidi false; done
For any vte-using terminal, you can disable bidi support temporarily with
printf '\e[8l'
but this only lasts until the terminal is reset. If you put this in your shell prompt, it'll help in command line applications, but not in full-screen applications. In bash:
PS1='\[\e[8l\]'$PS1
In zsh:
PS1='%{\e[8l%}'$PS1
A more general terminal-independent way to effectively disable bidi support is to change the terminal's reset sequence to include \e[8l. The terminal name (value of $TERM) in vte is xterm-256color. See How to stop cursor from blinking for explanations. This command will only affect new terminals, not ones that are already open.
TERM=xterm-256color infocmp -1 | sed '/^.rs[12]=/ s/,$/\\E[8l,/' | tic -

A few days ago, my ubuntu console started printing '^A' whenever I hit 'CTRL+A', instead of moving the cursor to the start of the line as it did before. The same problem happens for 'CTRL+E', while the 'CTRL+Arrow' shortcuts behave as they should.
However, if I log in to a remote machine via ssh, everything works fine.
Unfortunately, I do not remember anything in particular which could have triggered this behaviour (I have not changed shortcuts, nor modified my '.bashrc' file, nor updated the system).

I need to start an application automatically within a terminal like xterm or gnome-terminal in one command line. Is that possible?
|
Umm, yes. I'm leaving out the "without user intervention" bit here, because I don't know what that means in this context.
With xterm:
xterm -e somecommand
The terminal will exit as soon as somecommand exits. If that's not wanted, you may explicitly start an interactive shell as well:
xterm -e sh -c 'somecommand; bash'
See the xterm manual (man xterm).
I'm sure that gnome-terminal can do the same (see its manual).

I am on a SUSE Linux Enterprise Desktop 11 (SP4) machine, with Gnome 2.28.2 running. I set a keyboard shortcut to launch "gnome-terminal" command. And I also added a Launcher shortcut to Panel to do the same.
The launcher shortcut on the panel works correctly. It brings up the terminal and sources my profile and changes directory to my home directory.
But the keyboard shortcut brings up the terminal, does NOT source my profile and changes directory to /
How can I make the keyboard shortcut open the terminal while also sourcing my profile and cd-ing into my home directory?

Answer 1 - Modify gnome shortcut to open correct directory
It is possible to modify shortcuts in Gnome using the gconf-editor, which you may or may not need to install by running the following command.
yum install gconf-editor
After starting the program you will go to apps > metacity > keybinding_commands as seen in the image below.
Next you will select an unused or modify an existing shortcuts "value' to the following:
gnome-terminal --working-directory=/path/to/dir
This will not source your .profile, but it will ensure the shortcut opens in the appropriate directory.
Answer 2 - Change default working directory in Gnome
It is possible to modify default working directory in Gnome using the gconftool-2, which you may or may not need to install by running the following command.
yum install gconftool-2
Then run the following as your user to fix the current session
gconftool-2 --set --type=bool /apps/nautilus-open-terminal/desktop_opens_home_dir true
Then as root, run the following command to make this take effect on login
gconftool-2 --direct --config-source xml:readwrite:/etc/gconf/gconf.xml.defaults --set --type=bool /apps/nautilus-open-terminal/desktop_opens_home_dir true

When I resize my terminal, weird artifacts start to happen. The past lines start to get mixed. Here's a gallery with what I mean.
What is the problem here? How do I fix it? What part of the stack is causing the problem? Is it the Terminal? The shell?
I'm using GNOME-Terminal with zsh on Ubuntu 16.10. No, manual reset doens't solve the problem.
|
gnome-terminal (more precisely the VTE widget), unlike most other emulators, rewraps its contents upon resize. Generally this is a useful feature getting great feedback from users; however, with shell prompts, it indeed often causes weird behavior.
With the date being printed in the right margin, when you resize the window to become narrower, the prompt is wrapped into two lines by gnome-terminal. Afterwards, zsh is notified of the window size change and it repaints its prompt without knowing that gnome-terminal has wrapped it into two lines.
You can try to have a much simpler prompt (without stuff being aligned to the right), or disable rewrapping in gnome-terminal's profile preferences.

I just installed ubuntu GNOME 16.04. So far, so good.
When I run "GNOME terminal", I can do the all the things. But when asked to press "Enter", and I press the button labeled "Enter" on my kepboard near the keypad, it just does an error squirt-beep.
If I press the button above right shift (labeled <-|), it works.
How can I get the Keypad's "Enter" button to work in gnome terminal?
Thanks!
Update this fixed itself (rather I have no idea what fixed it). It was a new install: zsh, oh-my-zsh, custom profiles, software, 20 reboots, etc.
|
The two Enter keys are different. The one above the right-shift key sends a carriage-return character (which the terminal driver translates to line-feed as newline), while the other may send an escape sequence when the keypad application mode is enabled. Your instructions meant the former (unless the application uses curses, for example).
If you are trying to use a curses (or ncurses) application, you still are not guaranteed that you can use the two interchangeably. Some developers are confused by the difference, and ignore KEY_ENTER when they notice that the Enter key on the keyboard sends just a carriage return.
Along with that, some terminal descriptions have been written (no surprise) which equate kent (the terminfo name for KEY_ENTER) with carriage return or line feed. A lot of those are for obscure terminals which you probably do not use (and they represent a minority of the terminal descriptions). For xterm, kent is assigned to the escape sequence. It's been there a while (predating gnome-terminal):
# 9.11.3 (Thu Nov 9 12:14:40 EST 1995):

cp file.c $_
instead of copying file to destination , it create a file in current directory named _filedir.
Same happen with mv command
mkdir test
mv file.c $_
instead of moving file to destination, It moving in the name _filedir.
To find the problem i use echo
$ mkdir test
$ echo $_
_filedir
Why is $_ not working with cp, mv commands?
|
$_ - Gives the last argument to the previous command. At the shell startup, it gives the absolute filename of the shell script being executed. When you execute
mkdir test
mv file.c $_
Check if your mv, cp is an alias
In bash to acces the last arg to the previous command in History use !:$ ,like:
> mkdir test
> mv file.c !:$
mv file.c test

I was trying to build the AWN from source, and I installed a bunch of glib/gio dev packages required by libdesktop-agnostic (also built from source) that affect gsettings.
At some point during this, I rebooted and found that I couldn't launch any gnome-terminal. (Other gnome apps work normally.)
When I use the nemo-extension terminal (that's a gnome-terminal embedded into nemo) I get the following:
(gnome-terminal:11314): GLib-GIO-CRITICAL **: g_settings_get: the format string may not contain '&' (key 'monospace-font-name' from schema 'org.gnome.desktop.interface'). This call will probably stop working with a future version of glib.
**
ERROR:terminal-app.c:1449:terminal_app_init: assertion failed: (app->default_profile_id != NULL)
Aborted (core dumped)
I checked 'monospace-font-name' in the schema 'org.gnome.desktop.interface' using dconf-editor, here's what gsettings get says:
~ $ gsettings get org.gnome.desktop.interface 'monospace-font-name'
'Monospace 10'
~ $
No ampersands there.
It seems like having some libglib/gio's installed at once also causes the following related, similar gnome error-quarks that break gnome-notifications:
[gnome-control-center] notifications: fix invalid format string | mail.gnome.org
gnome-terminal: GLib-GIO-CRITICAL messages from gnome-terminal-server | bugs.debian.org
Which are great, but I'm kinda a novice at most of linux's technical-ness and I don't know really how (or, importantly, WHERE) to apply said patches.
Before you ask, I don't know which packages are causing this (there are waaaay too many in the libglib namespace) and I can't easily single them out one at a time without breaking lots of things.
Yes, all my repositories are official and yes, everything is up-to-date and in order as far as I can tell.

I had this problem. Exactly the same issues, to the point - I am running Linux Mint 17.2 Rafaela (ubuntu 14.04/trusty) running Cinnamon2.6.1.3 amd64; except it's an Asus machine.
I am with you, I want my gnome-terminal back. This is what I did to fix it:
sudo apt-get update
sudo apt-get upgrade
sudo apt-get dist-upgrade
That was it. The problem was that libglib and the other packages were too new to work with gnome-terminal. So a full distro upgrade fixed all the dependencies. This probably happened after a system update and a reboot. Until the system is rebooted, it will still work fine. But only after that it throws the errors.

Working with Linux Mint Cinnamon and Gnome Terminal, how do I use the term/colors files available from here:
http://dotshare.it/category/terms/colors/
|
All the files there are X resources files for Rxvt (most of them specifically for Urxvt, the Unicode-aware version of Rxvt). They are not generic terminal emulator configuration files, they are configuration file for that specific terminal emulator. They can't be used by Gnome-terminal.
If you want to try them out, install the rxvt-unicode package. Download one of the Xdefaults file and run
XENVIRONMENT=/path/to/Xdefaults urxvt
If you want to make one the default:
Many of these files are badly written and will work with the explicit XENVIRONMENT, but not the .Xresources method. If there are lines that contain comments starting with #, remove them or replace the # with !, which is the comment start character in X resource files. Also, if there are any lines beginning with * or ?, add Rxvt before it. For example http://dotshare.it/dots/1042/ should start with
! rxvt-unicode (urxvt) v9.15 - released: 2012-01-21
Rxvt*color0: #0C0C0C
…
Whitespace doesn't matter but capitalization does.
Copy the corrected file to ~/.Xresources. This file is loaded when you log in. To apply the settings now, run xrdb -merge ~/.Xresources.

I am using gnome-terminal in LXDE. When I have several gnome-terminal windows open, after some time the cursor in the inactive window starts to blink as well, as if the inactive window was actually active.
This only happens with gnome-terminal. Other terminal emulators such as LXTerminal work fine.
see video of the problem here: http://youtu.be/nRBehoJ1L7Y
I am aware of this bug. But this should have been fixed in my version of xserver-xorg-core 1.12.4-6. I am using Debian Wheezy and gnome-terminal 3.4.1.1-2
I am wondering if this could be caused because I am using gnome-terminal on LXDE. Could there be some gnome component missing? I have no way of testing if the same problem exists on Gnome.
|
You can switch to terminator.
It is an awesome full featured terminal emulator. It is a bit ugly (in my opinion) when you install, but can easily customize it and even made it look like gnome-terminal.

and then use

|
The environment setup when providing - is much more complete. From the man page:
The optional argument - may be used to provide an environment
similar to what the user would expect had the user logged in directly.
In particular SESSION_MANAGER is missing if you do su root.
You can output the environments by using env | sort > /var/tmp/XXX.env with XXX being different for the - and root invocation, and then compare the output using diff. In my setup (Ubuntu 12.04) this results in about twice as many lines in the su - case (53 vs. 27).

How do I change the default gnome-terminal location on screen. I checked out the preferences but they only have option to change default size. I also checked out .gconf/apps/gnome-terminal/ but didnt find any thing out.
All in all my gnome-terminal should normally be gnome-terminal --geometry=80x24+200+200
I dont want to do it through launcher because I will always have to start the terminal from launcher to get that location.
|
If it's only the sublime plugin that's bothering you, you just have to edit the plugin preferences and add the geometry parameters:
Preferences > Package settings > Terminal > Settings - Default
{ "terminal": "",
"parameters": ["--geometry", "80x24+200+200"]
}
Another way, if you also want Alt-F2 to open a terminal at that location:
gnome-shell Alt+F2 runs commands in your $PATH so you could create a new executable (e.g.gterm) somewhere in your $PATH (e.g. /usr/local/bin).
Edit /usr/local/bin/gterm like this:
#!/bin/sh
exec gnome-terminal --geometry 80x24+200+200
make it executable:
chmod +x /usr/local/bin/gterm
Now you can run gterm via Alt+F2, it will open a terminal @80x24+200+200. You can also point sublime to gterm (note there's no need for parameters anymore since gterm is already a custom size/position terminal):
Preferences > Package settings > Terminal > Settings - Default
{ "terminal": "gterm",
"parameters": []
}

tmux (or screen, the older alternative) are great for this.
tmux lets you do both horizontal and vertical splits.

I want to view mplayer's normal terminal output, and also write it to a log.
That works fine when I run mplayer from the commandline, eg:
mplayer "$HOME/gdr01.wav" 2>&1 |tee $HOME/junk.log
However, I want to launch mplayer in it's own gnome-terminal window. Neither of the following commands write to the log, althought the terminal display works.
(gnome-terminal -e "mplayer $HOME/gdr01.wav 2>&1 |tee $HOME/junk.log" &)
gnome-terminal -e "mplayer $HOME/gdr01.wav 2>&1 |tee $HOME/junk.log" &
What is at play here, and what is the trick to get it to work?
EDIT: The problem is that I get the terminal's mesages being written to the log (eg. an ibus warning). However, although mplayer generates thousands of lines, none are written to the log.
|
What's going on is that gnome-terminal's command line parsing is funky. You're running mplayer with /home/ferer/gdr01.wav, 2>&1, |tee and /home/ferer/junk.log as arguments. If you wait for the end of the audio file, you'll see error messages about these nonexistent files for a microsecond before the terminal closes.
Either figure out gnome-terminal's intricate rule. Or, what I recommend: yse the -x option instead of -e and invoke a shell explicitly.
gnome-terminal -x sh -c 'mplayer "$HOME/gdr01.wav" 2>&1 |tee $HOME/junk.log'

I'm not sure what's exactly wrong, but you can probably check the journal for log of the gnome-terminal-server.service user service to see if it actually reported anything:
journalctl --user-unit gnome-terminal-server.service
The systemd service is started via dbus through its "companion" dbus service file. There will be only one server instance at a time and the server will exit whenever all the windows/tabs have been closed. So what you are experiencing indicates that it occurs every time during the starting up of the server. It could be the "channel" (dbus) that has problem. It could also be just a problem of the server process itself.
You may also want to just check journalctl -e and journalctl --user -e after the problem occured in case it is something else that is stalling the startup.
For the record, it's not expected to be slow even if you are not in a GNOME session and/or not using GDM to start your window manager. In my experience it still starts faster than the python-based terminator anyway in normal circumstances.

I want a command that opens a terminal and executes a function that is defined in my aliases.zsh. The function is defined like so:
my-function() {
wget some stuff
do some other stuff
}
I tried gnome-terminal -- my-function, but the new terminal reports that it Failed to execute child process “my-function” (No such file or directory). Something similar happens if I do gnome-terminal -- /bin/zsh -c 'my-function; sleep 1; exec zsh': in the new terminal, zsh reports zsh:1: command not found: my-function.
Any help greatly appreciated.
|
~/.zshrc is the customisation file for interactive invocations of zsh.
zsh -c 'some code' is an inline script. Like for scripts starting with a #! /bin/zsh - shebang, thankfully, the ~/.zshrc is not sourced on startup. If it were, and you had aliases / functions that change the behaviour of standard commands (it's not uncommon to have alias 'ls=ls --color -F' 'grep=grep --color;...), that could break zsh scripts.
If you want a script to load ~/.zshrc or ~/.zprofile or /etc/zsh/zshrc, you need to request it explicitly. But best would be to put those functions in some ~/.zsh/some-library.zsh and source that instead in the scripts that need it as well as your ~/.zshrc, or use the autoload framework.
gnome-terminal -- zsh -c '. ~/.zsh/some-library.zsh; myfunction'
If you wanted an interactive zsh to be started in gnome-terminal but that first runs your function before issuing the first prompt, you could add a:
eval -- $ZSH_INIT_COMMAND
unset ZSH_INIT_COMMAND
To the end of your ~/.zshrc, and run gnome-terminal as:
gnome-terminal -- env ZSH_INIT_COMMAND='myfunction; echo and whatever else' zsh
Or if you wanted to start it as if it had been written at the prompt, so you could handle it the same way, change it to:
if (( $+ZLE_INIT )); then
seed-zle() {
BUFFER=$ZLE_INIT
unset ZLE_INIT
zle -D zle-line-init
unset -f seed-zle
zle accept-line
}
zle -N zle-line-init seed-zle
fi
And start gnome-terminal as:

I have a live running mate-terminal whose scrollback buffer already contains a lot of text with color/bolding, but (unfortunately) no screen management/capture program (like script/screen/tmux) was started on the terminal. Is it possible to copy the existing scrollback buffer contents to a file, preserving all escape sequences?
There is an answer to this problem for xterm by Thomas Dickey, but even in that solution the color escape sequences are not getting saved to the file specified by the printerCommand resource. but I am looking for a solution for mate-terminal.
Edit note: It seems unlikely that a solution for this problem exists
for the mate-terminal; see the comments in Thomas Dickey's answer below.
Just to be clear, pre-starting a terminal screen management/capture program (like script or GNU screen or tmux) is not an option, because here we want to copy terminal output already produced before starting any such program.

You may have overlooked the printAttributes resource:
printAttributes (class PrintAttributes)
Specifies whether to print graphic attributes along with the
text. A real DEC VTxxx terminal will print the underline,
highlighting codes but your printer may not handle these.
o "0" disables the attributes.
o "1" prints the normal set of attributes (bold, underline,
inverse and blink) as VT100-style control sequences.
o "2" prints ANSI color attributes as well.
The default is "1".
The default resource value makes it compatible with DEC terminals; color is something that you can configure.

The thing about error messages is that they tell you what's wrong.
Your error message clearly says that there is an unterminated quoted string in /etc/environment. Once you read that, you should investigate that file to see if it looks odd with regards to double quotes.
In a comment, you mention that your /etc/environment file has the contents:
PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games" :/usr/java/jre1.8.0_171/bin"
JAVA_HOME="/usr/java/jre1.8.0_171"
(or something similar, formatting is difficult in comments).
Here, you can clearly see that the :/usr/java/jre1.8.0_171/bin" bit at the end of the first line looks out of place (and a space too many).
You, or a script, have edited the file and messed up the PATH. That line now contains an unbalanced double quote.
My guess is that the PATH should be set as:
PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/usr/java/jre1.8.0_171/bin"

When I login (using ssh) to other host and open a new tab (pressing CTRL + Shift + T). It sets current working directory to a particular directory in my home independent from current working directory on remote host.
So what can be the reason for this behavior?
And how can I change it?
I am using RedHat.
|
When you press Ctrl+Shift+T, Gnome-terminal looks at the current directory of the process that's running in this tab, and switches to that directory to run the process in the new tab.
Observe that if you type bash in a Gnome-terminal tab that's already running a shell and is in /directory1, and you run cd /directory2 in that instance of bash, then press Ctrl+Shift+T launches a new tab with a shell in /directory1. Gnome-terminal only looks at its child process's current directory, not at its descendants. (That's the only reasonable way, really: how would it decide which descendant to pick?)
When you run ssh to open a shell on another machine, Gnome-terminal does what it always do: when you open a new tab, that tab starts in the directory of the shell from which you ran the ssh command.
Gnome-terminal has no way to know about the current directory on another machine. To do that, it would need some very tight integration with SSH and with the remote shell. I'm not saying it's impossible — Emacs's Tramp parses the prompt from the remote shell to figure out the remote directory — but it has a cost in complexity, reliability and flexibility. Gnome-terminal gives you a terminal and lets you do what you want in it; Tramp takes control of the SSH connection and doesn't cope with arbitrary behavior of the remote shell.
You cannot change this without doing some nontrivial development work. You could use Emacs as your terminal emulator (but of course Emacs is far from being a drop-in replacement for Gnome-terminal, you'd need to pick up different habits). If all you need to do on the remote machine is manipulate files and not run programs, you can mount the files over SSHFS, and then you'd only be running a local shell so you'd get the current directory tracking that you want. But by far the simplest way to create a new tab in the same remote directory is to create a new tab, run the same ssh command, and copy-paste the remote path.

If the ESC ] 0 escape sequence works to change your terminal's title when you use it locally, it also works across SSH. SSH doesn't change the traffic between the application and the terminal.
If you run applications in a screen multiplexer such as screen or tmux, these do interpret escape sequences by themselves and send others to the terminal. That's independent of SSH, except inasmuch as you might be more inclined to use screen on a remote machine than locally.
The shell on the remote machine may well be configured to set the remote title whenever it starts to execute a command or whenever it displays a new prompt. This is usually done by printing the title-changing escape sequence as part of the prompt, so check the content of the PS1 variable:
printf '%s\n' "$PS1" | cat -v
If the remote shell is bash, also check the PROMPT_COMMAND and the DEBUG trap:
echo "$PROMPT_COMMAND"
trap -p DEBUG
If the remote shell is zsh, check PS1, RPS1 (rare), and the precmd and preexec functions.
print -rl $PS1 $RPS1 $functions[precmd] $functions[preexec]

I want to open my terminal with some commands executed in it on bootup. So I wrote a script with following line in it:
gnome-terminal --tab -t "MyPC" -e "sh -c 'firefox &;exec bash'" --tab -t "MYPC2" -e "sh -c 'ls;exec bash'"
In this firefox & is not executing, however if I write only firefox it executes.
So only the second tab is opening not the first one
I know it's some spacing issue. If I write just ls that also executes.
What is the correct syntax? Why is it not taking spacing??
|
Putting a ; after a & does not work. & is already a command separator, specifying, that the command should be run in the background, so ; is not required.
Try removing the ; and report back.

I have a very strange problem on my Ubuntu 14.04 machine. I can't use some letters like r and i in gnome-terminal.
Note: when my CapsLock is on I can type R and I in terminal. The problem on my terminal is for just these two letters when in lowercase. For example I can't use the rm command.
UPDATE #1
I used:
$ sudo su
Now as the root user I can type r and i.
What is the problem? How can I fix it?
|
I found the problem. I decided to activate tab completion in Python's interactive mode.
So I added the following lines to /home/user/.inputrc:
import rlcompleter, readline
readline.parse_and_bind('tab: complete')
So when I rebooted my machine the keys r and i from import and readline effected on my keyboard.

This is embarrassing, but I don't seem to be able to set the command-prompt or the shell title. I'm using Gnome3 on centos 7.
PROMPT
I've added the following to ~/.bashrc:
export PS1="\w \$ "
The prompt stays the same:
echo $PS1
[\u@\h \W]\$
I've also tried updating the ~/.bashrc without the export:
PS1="\w \$ "
Same result.
It is almost like something is overriding it.
TITLE
As for the title I've tried the following:
echo -ne "\033]0;hi\007"
It doesn't take effect.
|
Here is what I had to do in my .bashrc
export PS1="\\n[\\!. \\t - \\w]\\n>"
set_title() {

}

In Fedora 16, when accessing the Windows partitions via the Fedora GUI, it would get mounted on /media/. They were visible as /media/Data etc and I was able to navigate into those partitions via the terminal. But now I see the partitions mounted on the GUI, but they're not visible in /media/. Could you help with navigating to the partitions via the terminal?
Or to put it in another way: Where do the Windows partitions get mounted to, when mounted via the GUI?
|
Fedora uses as standard the gnome desktop. Gnome uses a virtual file system called gvfs, to represent network shares. They are not mounted to a specific mount point. If you want to browse those mounts via terminal you have to use the gvfs tools (gvfs-*).
If your partitions are mounted the old way then just type mount to find out where they are mounted.

I recently started using a bash script to setup terminal workspaces for myself, and everything worked fine for the first couple of days. I run the script, and four or five or seven terminals pop up, all in precisely the right places on the screen, all cd'ed into the proper directories, ready for use.
This morning I installed conky, and the next time I tried to run my script, the oddest thing hapened. Now it will only open the first window. When I close that window, the second one opens. When I close that one, the third, and so on until the end of the script.
So now my script is useless except as a pasteboard for me to copy and paste into the terminal from.
Here is my script:

if [ $1 = "deploy" ]; then

Append an & to the end of each gnome-terminal command to make sure each terminal starts in the background. If you haven't killed them sooner, the terminals will exit when conky exits and kills all child processes.

Trying to create a command that rename terminal title and run a application, I'm adding the commands inside .bash_aliases file. The rename command I'm using is: PS1='\[\e]0;test\a\]${debian_chroot:+($debian_chroot)}\u@\h:\w\$ '
If I use it alone and after run the application it works as expected. But if I use the command like this:
alias rpcs3="PS1='\[\e]0;test\a\]${debian_chroot:+($debian_chroot)}\u@\h:\w\$ ' && ./rpcs3/rpcs3-v0.0.25-14385-b639f3c8_linux64.AppImage"
Using this latter command, the terminal title only change after the application is closed as shown in the example below:
Before closing the app
After closing the app
What should I do?
|
The alias is not working because the shell prompt waits until your program finishes.
A solution to this is by first calling to your command ./rpcs3/rpcs3-v0.0.25-14385-b639f3c8_linux64.AppImage and run it in background:
alias rpcs3="./rpcs3/rpcs3-v0.0.25-14385-b639f3c8_linux64.AppImage & PS1='\[\e]0;test\a\]${debian_chroot:+($debian_chroot)}\u@\h:\w\$ '"
And given that your command will run in background when you press Enter you will get back to shell prompt (the title will be set before, so this has no problem anymore). If you want to get back to foreground the process ./rpcs3/rpcs3-v0.0.25-14385-b639f3c8_linux64.AppImage you should use the command: fg.
For getting which jobs are running in background in your current shell you can use the command/shell builtin jobs. For example:
$> jobs -l
#Output
[1] Running gnome-calculator &
[2]- Running gnome-calculator &
[3]+ Running nautilus &
If I want to get back to foreground the nautilus process I can use:
fg 3
#You can also specify the `command name` instead of the ID.
Probably in your case you only will have one process in background (./rpcs3/rpcs3-v0.0.25-14385-b639f3c8_linux64.AppImage). So you can simply use fg 1.

I saved terminals with:

I started using Sublime Text 3 to compile my FreeFem scripts (interpretator PDEs package solver) under Ubuntu 14.04. To invoke the interpretator I customized the build system as follows
"shell_cmd": " gnome-terminal -x sh -c \"FreeFem++ $file ; exec sh\""
Every time I run compilation I want to create a separate terminal process that launches FreeFem++. But when I press Ctrl+C it kills the terminal. Instead of this I want to terminate process but leave the terminal window open.
|
Ctrl+C kills the shell as well as the FreeFem subprocess, because the SIGINT signal is sent to the whole foreground process group. Since the shell is not interactive, the subprocess runs in the same process group. See Why is SIGINT not propagated to child process when sent to its parent process? and What is the purpose of abstractions, session, session leader and process groups? for some background on process groups.
You can cause the shell not to die when it receives SIGINT by setting a trap for it. (Don't ignore the signal: that would also cause it to be ignored by the subprocess.)

I have hit a few CTRL- in command line and I see the text in the terminal getting smaller with every invocation. What is going on here and is there a way to redo ie magnify the text to bring it back to the original size via a command?
Edit: As per Christopher's suggestion in the comment I can get back to my original font size by hitting CTRL+ but I would still like to understand what is going on behind the scenes here.
|
It's a somewhat standard keyboard shortcut (it works in Konsole, too).
It's simply bound to reduce font size (and simmetrically, Ctrl+ to increase font size).
You can easily disable/modify by going to the shortcuts preferences:

I use Linux terminal in Ubuntu.
When I write seq 100 1 | less & to run it it in the background, it just stops.
I used other ways to run it on background too, like using bg [jobnr] but it just stops.
I find the job number, and write bg 1 (when it's 1), but then I check the process and it's not running.
The same happens with man pi too or other "man pages".
But pi 10000000 can run on background, and when it's finished it just prints the pi-number on terminal.
It was an assignment to see if less can be run on background, and why it can't be run on background. After search online I didn't find much information about why.
Why does some processes can't be run in the background but others can do run despite both printing on terminal?
|
less cannot run in the background because it's trying to interact with the controlling terminal, which cause it to be forcefully stopped. Only a foreground process can read from the terminal or change the terminal settings.
When a background process tries to change the terminal settings, it gets a SIGTTOU signal. When it tries to read from the terminal, it gets a SIGTTIN signal. Both signals cause it to stop. If a process goes on and ignores those signals, the operations which caused them may fail, so this is not a way out of this (e.g. a read from the terminal will fail with an EIO error).
Notes:
less is peculiar by the fact that in order to be able to be used as command | less, it opens the controlling terminal directly via /dev/tty instead of assuming that the controlling terminal is its stdin or stderr, as other interactive programs like most editors or shells do.
You can configure your terminal with stty tostop so that background programs which try to write to the controlling terminal will be stopped too, but that's not the default anywhere, and not very practical.

I want to be able to launch a terminal emulator (preferably gnome-terminal) with interactive zsh running inside using a custom prompt string. I don't want to modify my default prompt string in .zshrc because I use that most often and it is just occasionally I want to launch a terminal with a custom zsh prompt string (more specifically, I want the time to show up in the right hand side prompt).
If I already have a terminal window open, I can solve this by running:
export RPS1=%T zsh
But I can't figure out the syntax for making this work together with launching a new terminal instance. This is what I have tried with the error message below each command:
gnome-terminal -- export RPS1=%T zsh
# Error: Failed to execute child process “export” (No such file or directory)
gnome-terminal -- sh -c export RPS1=%T zsh
# Prints all the options, like with `set`
# and then exits with "The child process
# exited normally with status 0".
gnome-terminal -- sh -c "export RPS1=%T zsh"
# The child process exited normally with status 0.
gnome-terminal -- sh -c "export RPS1=%T; zsh"
# This start the terminal with zsh, but the RSP1 is not changed
I considered reading a custom rc file, like in this answer, but there does not seem to be a way of doing this in zsh without using source, which was giving me similar problems as above.
|
In zshrc, allow for overriding RPS1 by setting it as:
# If rps1 is not set, use a default value
RPS1=${rps1-"Your usual RPROMPT"}
Now you can launch a command with a different RPS1 by setting rps1 in its environment, for example:
rps1=%T gnome-terminal
The parameter expansion form ${param-word} allows RPS1 to be set to null:
rps1= gnome-terminal
Parameters used by the shell (such as RPS1) needn't be exported. They are used to set up the shell, so should be set once in the rc file.
If a program (e.g. gnome-terminal) is launched with rps1 in its environment, any subsequent programs launched from it will see rps1 in their environment. To avoid this, either of the following could be added to zshrc: unset rps1 (after using it to set RPS1) or typeset +x rps1.
BTW, the following will export two shell variables:
export RPS1=%T zsh
The above is export with two arguments, resulting in RPS1=%T & zsh='' being created in the environment
To set RPS1 in the current shell, simply do:
RPS1=%T

When I try to use write to talk to users logged into an X session results vary depending on which terminal they are using. Gnome terminal can pick up writes, but neither lxterminal nor terminator can. The reason is that lxterminal and terminator don't have associated pts devices:
With lxterminal(s) running:
$ who
tshaw tty7 2013-01-27 21:34
With Gnome terminal running:
$ who

tshaw pts/1 2013-01-27 22:25 (:0)
(the tty7 entry in the above is the X session)
Is there a way to configure other terminals to take pts devices or would that have to be done in source code?
|
Original question
All of the mentioned programs have a pts. The problem is not that your specified terminals don't have a pts device but that the information isn't recorded.
Why doesn't lxterminal or other terminals show up in who
who retrieves it information from a utmp file, typically /var/run/utmp and is written to by programs themselves. In order to write an utmp entry programs have to have access to the file which normal, standard applications like lxterm or urxvt don't have.
Allow access to /var/run/utmp for applications
Typically /var/run/utmp is not write-able for the normal user, i.e. programs can't create new entries as a malicious user could just overwrite the file or write fake entries.
On my system /var/run/utmp has following permissions:
$ ls -l /var/run/utmp
-rw-rw-r-- 1 root utmp 3072 Jan 28 08:26 /var/run/utmp
that means in order to write to the file you have to have at least to be in the group.
The best solution to give permissions to programs for updating /var/run/utmp is changing the permissions of the program so it can update the file. You can do this by setting the group of the executable to utmp and set the setgid flag which means it will set the group id from the file permissions, i.e.:
chgrp utmp /usr/bin/urxvt
chmod g+s /usr/bin/urxvt

This requires a two step process.
you need to start gnome-terminal running a program that waits for commands to be "sent in"
you need to speak to said program to make it execute the things you want it to execute.
The right syntax to start gnome-terminal with a command to execute is
gnome-terminal -- command
not gnome-terminal --command as you did.
Having sorted out how to do 1., we need to find a program that does serves as a daemon that will listen to commands being sent in.
tmux is such a server. You can run
gnome-terminal -- tmux -L 'a unique name for a socket'
to start your gnome-terminal with an empty shell inside.
You can then use tmux' CONTROL MODE to send commands to that tmux server, e.g. to attach to the session currently displayed in the gnome-terminal, then make a new frame in that, running your command of choice in that frame. See man tmux for more detail.
Honestly, though:
gnome-terminal is an interactive terminal emulator. You just seem to want to display some output in a graphical manner; you don't seem to expect gnome-terminal to get input from the user. The right thing to do in that case is simply not use gnome-terminal, but use whatever you're planning to use to send commands to display a window with a constant-width font text field, and print whatever output you want there.

What is the meaning of this code: gnome-terminal --tab -e "sh -c 'ch/home/Desktop'"\
could you tell me the meaning of each part of this code, one by one?
|
I'm afraid that code doesn't mean much, most likely. The breakdown is:
gnome-terminal: this is the default terminal emulator of the Gnome desktop environment. This command will open a terminal, everything that comes after it is options and arguments that modify what gnome-terminal will do. These are:
--tab : this will open a new tab in your currently open terminal.
-e: this tells gnome-terminal to run a command when it launches.
In your case, the command is sh -c 'ch/home/Desktop' which means "use the shell sh to run the shell script found at ch/home/Desktop.
Now, that path is almost certainly wrong, since it expects to find a local directory named ch which has a subdirectory named home which in turn contains a subdirectory named Desktop. While it is possible that you have these directories on your system, it seems unlikely and you probably want /home/<YOUR USERNAME>/Desktop.
Next, this is almost certainly a directory and not a shell script (which is a file). So you can't actually run it with sh. I am guessing you wanted to do something very different, perhaps pass the path to a script you have saved on your desktiop. If so, assuming your user name is skinner and the script is at /home/skinner/Desktop/my_script.sh, you would do:
gnome-terminal --tab -e "sh -c '/home/skinner/Desktop/my_script.sh'"
Finally, the trailing \ at the end is most likely a typo, but it will block execution if you include it since having \ at the end of the line "escapes" the end of the line character (newline, \n) which tells the system the command continues on the next line, so it will only be executed after you hit enter again.

If I quit it and relaunch it, transparency works fine.

About my system information... I am using Kubuntu with KDE plasma v:5.18.5.
Here is what I did.
I installed "gcc" from the terminal window.The "gcc" is a program that translates the C language text code in machine code.
I have have created a text file, called "start-guake.c" and then I written the code in that text document(the extension must be ".c" not ".txt").
After that,in the terminal, I changed the directory to the location of the text file and I COMPILED it with "gcc" (in the command line write gcc followed by the path of the text file that contains the code: "gcc /path/to/file.c"). This action resulted in the creation of a file named "a.out" (you will find it in the same folder where you have your text file that contains the code)and this is the actual program.
I renamed the file from "a.out" to "start-guake" and moved it in the "/bin/" directory.
From there I went to my applications menu and opend "autostart" and in there I added the newly created program.
I restarted the computer after all these steps.
This is the code:
#include <stdlib.h>
#include <stdio.h>
#include <string.h>
void waitTenSeconds();
int main(){
waitTenSeconds();
system("guake");
return 0;
}
void waitTenSeconds(){
system("sleep 10");
}
Hope this helped.
Good luck !

When I press Ctrl + Alt + F1 the desktop environment disappears and a terminal window appears. Pressing Ctrl + Alt + F7 brings me back to DE.
This terminal is useful when the DE hangs for some reason and I need to kill a process or something.
However the keyboard typing speed in this terminal is so fast that its almost unusable.
Attempting to type sudo ps -ef | grep virtualbox often gets me suuudo pss -ef || grep virtuaalbox
I have two questions -
What terminal is this? Is it Xterm?
Could I reduce the keystroke speed to a more usable value, as in gnome-terminal?
|
What you get when you press Ctrl + Alt + F1 is not Xterm, or anything to do with X or your DE. It is called a TTY (a shortening of TeleType, see here for some history). The command you want is kbdrate. The -d option lets you set the delay before it starts repeating keys, and the -r lets you set the rate at which keys repeat after they've started. You need to run kbdrate as root. Also, not all settings are valid, see the man page for details.

In Gnome Terminal (Version 3.44.1 for GNOME 42), the shortcut ctrl+L clears the terminal (similar to the clear command). There does not appear to be an entry for this in the shortcut preferences. How can I disable it?
|
You did not tell us what your shell is.
Bash
Bash uses readline. In your Bash bind -p | grep C-l probably prints:
"\C-l": clear-screen
(possibly among other lines). To disable Ctrl+l, you need to remove this binding. In Bash the command is:
bind -r "\C-l"
To disable permanently for Bash, put the above command in your ~/.bashrc. To disable permanently for any tool that uses readline, put the below line in your ~/.inputrc:
"\C-l":
More information: help bind, man bash, man 3 readline.
Zsh
Zsh does not use readline. In your Zsh bindkey | grep '\^L' probably prints:
"^L" clear-screen
(possibly among other lines). To disable Ctrl+l, you need to remove this binding. In Zsh the command is:
bindkey -r "^L"
To disable permanently for Zsh, put the above command in your ~/.zshrc.
More information: man zshzle.

Is there a way I can make the gnome-terminal (Version 3.36.2) copying text I mark? Or do I need to install the xfce4-terminal for that? Or do you have any other pro suggestions for a terminal-emulator?
Thanks.

I found a work-around, which is even better:
Anything you highlight in Linux, regardless of the program, is put
into a special clipboard buffer, which you can paste using your
mouse's middle (wheel) button (which is emulated on many laptops by
pushing both buttons at the same time)

I have an application launcher that executes a command inside gnome-terminal with the -- option, but whenever I go into the terminal and try crtl-z to try to suspend the command and move it to the background nothing happens. My search found a bunch of posts about launching interactive shells in bash, but nothing I've tried there works either. Is there way to launch gnome-terminal and execute a command that gives me the ability to suspend the command and bring up a prompt later?

bash_in_gnome_terminal(){
local IFS
printf -v cmd %q ". ~/.bashrc; set -m; $*"
gnome-terminal -- bash -c "bash --rcfile <(echo $cmd)"
}
bash_in_gnome_terminal tail -f ~/.xsession-errors
bash_in_gnome_terminal 'grep -r pattern dir | less'
This solution is complicated (and crippled!) by the fact that the gnome-terminal command actually calls into a "terminal server" to spawn a terminal instance, and you cannot pass file descriptors to the process running in it.
With other terminals like xterm or mlterm the solution is simpler and more functional:
bash_in_xterm(){
local IFS
xterm -e bash --rcfile <(printf '. ~/.bashrc; set -m; %s\n' "$*")
}
Also, it would be nice if bash had an option to run some commands before an interactive shell (like vi +'cmd'), without a kludge like --rcfile <(...). Maybe it even has -- but I wasn't able to figure it out ;-)
The set -m is needed because bash sources the initialization files with the monitor mode off, ie without job control and the possibility of using ^Z, fg, bg, etc.
If you want the shell to exit and the terminal to close when the started command has exited, the function could be modified like this [assumes a recent version of bash]:
bash_in_gnome_terminal(){
local IFS
set -- 'sigchld(){ local j="\j"; ((${j@P})) || exit; }; trap sigchld CHLD;' "$@"
printf -v cmd %q ". ~/.bashrc; set -m; $*"
gnome-terminal -- bash -c "bash --rcfile <(echo $cmd)"
}
The ${var@P} form expands any prompt escapes in var, and the \j prompt escape expands to the number of jobs. Thence j="\j"; ((${j@P})) || exit as called from the CHLD trap will exit the shell if there are no more jobs.
In older version of bash which do not support the ${var@P} expansion form, a clunkier kludge will have to be used:
set -- 'sigchld(){ trap - CHLD; test "$(jobs -p)" || exit; trap sigchld CHLD; }; trap sigchld CHLD;' "$@"
Here the CHLD trap has to be disabled and then reenabled, otherwise the $(jobs -p) command substitution will trigger it recursively.
This whole thing could be made into a standalone script instead of a function:
#! /bin/bash
# uncomment and edit the following line accordingly
# set -- <fixed command and arguments> "$@"
# this only works in bash >= 4.4
# set -- 'sigchld(){ local j="\j"; ((${j@P})) || exit; }; trap sigchld CHLD;' "$@"
set -- 'sigchld(){ trap - CHLD; test "$(jobs -p)" || exit; trap sigchld CHLD; }; trap sigchld CHLD;' "$@"
printf -v cmd %q ". ~/.bashrc; set -m; $*"
gnome-terminal -- bash -c "bash --rcfile <(echo $cmd)"

Lets say I have top or some ncurses program running in a graphical terminal, and from outside this terminal I'd like to execute a command, that would replace top with another program of my choosing.
I imagine there to be a generic approach to this, something that
finds the PTY for the correct window
kills the program in the terminal, while keeping the PTY
Spawns the replacement command, and
hooks up PTY I/O to read/write to/from the command
My googling for preexisting generic solutions to wrap this has not yielded useful pointers.
The specific use-case I have for this: I want to switch the tmux client running in gnome-terminal from one /tmp/tmux-$UID/Socket (=server) to another one belonging to the same user, without "losing" the window.
I'm looking for the generic solution, because I could not get a connected tmux-client to connect/attach to a new socket at run-time.
|
To my knowledge there is no generic solution to do this. The tmux client is running in a pty which belongs to gnome-terminal, you can't change the pty gnome-terminal is talking to or change the program the pty belongs to (either the master or slave end) without gnome-terminal's participation or without some seriously fiddly code (for example, see reptyr, which does the reverse of what you want - moving a program to a different pty rather than a pty to a different program).
For tmux specifically, if your tmux is new enough (2.4 or later) you can use detach-client -E to replace the running tmux client with a different process - this could be another tmux client, for example:
tmux -Lfirstsocket detach -E 'tmux -Lsecondsocket attach'
If your tmux is not new enough, your options are probably limited to:
open a new tab in gnome-terminal with the new tmux client and close the original tab;
close your gnome-terminal entirely and open another one with the program you want;
open the new tmux inside the old tmux and then hide the status line and unset the prefix in the old tmux, so it is still running but won't get in the way.

compare the following screenshots of terminal
|
Selecting by default swaps the foreground and background color of the affected cells. (An explicit highlight color can be configured in GNOME Terminal's Prefences, or switched to using the OSC 17 / 19 escape sequences. But let's stick to the default behavior for now.)
If a space becomes yellow (orange, brown, whatever that color is :)) when highlighted, it means that its foreground color is this; which, due to the character being a space rather than a letter, is normally not visible.
apt maintains a temporary status bar (progress message) at the bottom of its output, erasing and overwriting it with messages that it intends to remain on the screen. You can notice that the text of that status bar is the same color as the highlight one. This means two things: apt removes the status bar's characters by overwriting them with spaces (as opposed to, let's say, a sequence that clears to the end of the line), and it does so before switching back from yellow to the default color.
You could file a bug request against apt to change to a more "highlighting-friendly" approach, although I assume it would be handled with extremely low priority. Let alone, other terminal emulators might implement different highlighting experience.

As I'm using bash on my Desktop, I have a multi-tab Gnome Terminal window with 6 to 10 shells opened in there.
When I log out of my X session, my ~/.bash_history gets updated in some random way... (at least if you ask me, I have not found a clear pattern to it.)
I'm wondering whether all the history from all the shells I had running could be appended. At this time, it feels like only one of the shells will save its history in the file (or rather they all do and the last one wins?)
What I think would be best is a way to save commands as I issue them from any one instance. That would certainly be the cleanest, if it's doable, as the order would be preserved (i.e. I cannot type in more than one shell at a time, so saving the history will be in the order I typed command in each shell.)

I have a folder with symlinks which are pointing to other folders, how can i recursively look into those folders? I would like to do a grep on those results to search for matches.
doing tree will only list the symlink as files.
|
You can use find with the -L option, e.g.,
find -L . -type f -exec grep foo {} \;
That makes find follow symbolic links. Quoting POSIX:
-L
Cause the file information and file type evaluated for each symbolic link encountered as a path operand on the command line or encountered during the traversal of a file hierarchy to be those of the file referenced by the link, and not the link itself. If the referenced file does not exist, the file information and type shall be for the link itself.

This works with xterm (see https://unix.stackexchange.com/a/739977/119816)
xterm -e "echo hello; bash"
but doesn't with gnome-terminal. What is the equivalent way of doing this with gnome-terminal?
gnome-terminal -- "echo hello; bash"
Gives this error:
I've tried various ways of quoting but no success. Some tries are:
gnome-terminal -- "bash -c \"echo hello; bash\""
#
gnome-terminal -- /usr/bin/bash /tmp/echo-hi
Where /tmp/echo-hi is a shell script that echos hi.
And several other variations.
|
bash -c should not be in the quotation.
Try the following:
gnome-terminal -- bash -c "echo hello; bash"
I am using this one for example:
gnome-terminal --window --title "neovim" -- sh -c "nvim"
This just executes the nvim binary with sh in a new gnome-terminal window with the title "neovim". In my case sh is just a link to the bash binary. So you can basically use any shell binary you want here.

I have a script which unexplainably forks a new Terminal instance on some Linux distributions... I'd rather it doesn't do this. Oddly, when I run the script directly (./install.sh) the additional Terminal instance doesn't get created.
curl qz.sh | bash # warning this will install a Linux Desktop App you may not want :)
On MacOS Mojave: Works normally
On Ubuntu 22.04: Works normally in a VM
On Fedora 34: Works normally in a VM
On Ubuntu 20.10: Reportedly spawns a new terminal
On Manjaro XFCE: Works ok until it reaches the sudo ... command in the script and spawns a new Terminal instance
Full source code here.
The code in question is as follows:
# Install using unattended techniques: https://github.com/qzind/tray/wiki/deployment
echo -e "Download successful, beginning the install..."
case $OSTYPE in
"darwin"*)
# Assume .pkg (installer) for MacOS
sudo installer -pkg "$TEMP_FILE" -target /
;;
*)
# Assume .run (makeself) for others
if which sudo >/dev/null 2>&1 ; then
# use "sudo" if available
sudo bash "$TEMP_FILE" -- -y
else
# fallback to "su -c"
su root -c "bash '$TEMP_FILE' -- -y"
fi
;;
esac
Question: Why does this spawn a new Terminal instance in some environments and how can I prevent this from happening?
|
The reason a terminal isn't created when running the installer directly is that makeself uses tty -s to determine whether it's already running in a terminal or not, see the source code on GitHub. When running curl qz.sh | bash you're opening a pipe that's not there when running the script directly, causing the tty -s test to fail.
To prevent the terminal from being opened, you can use makeself's --nox11 flag, citing the README:
--nox11 : Disable the automatic spawning of a new terminal in X11.

When I have a gnome terminal open, is there a command that will allow me to programmatically enquire of this gnome terminal:
How many tabs the gnome terminal has open on it?
What is the pwd of each of these tabs?
I lose my virtual machine in the evening, so I want to write a script to store the above information, and then programmatically reopen all the gnome terminals the next day, upon log in.
|
You can enumerate the open windows and tabs using dbus; going straight for tabs:
dbus-send --session --dest="org.gnome.Terminal" --print-reply /org/gnome/Terminal org.freedesktop.DBus.ObjectManager.GetManagedObjects | grep -c /screen/
will tell you how many are open.
If your shell cooperates with VTE, GNOME Terminal will knows about the last current directory for each running shell in your tab (not the current directory of the leaf process running in each tab, if it’s not the shell); but I don’t think there’s a way to retrieve that over the bus.
What you can do is list the current working directories of all the “leaf” processes whose parent is GNOME Terminal:
pstree -T -p $(pgrep gnome-terminal) |
sed -E 'sX^.*\(([0-9]+)\)$X/proc/\1/cwdX' |
xargs readlink -f
This won’t tell you which tab is where but I’m not sure that’s significant (as far as I can tell, there’s no way to determine what each tab is running). You can use variations of this to find out what is running too, not just the current working directories.

i have a script to launch gnome terminal with multiple tabs. The tabs are opened based on a list of directories listed in .tabs file that are in the same dir as the script.
I create a string with several --tabs --working-directory /some/dir one for each line in the tabs file.
before i run the command i echo it to the console. then i actually run it.
Problem is gnome does open the tabs but it doesn't open each one in it's working directory. However if i copy-paste what i printed to the console it works great. i can't figure out why.
here is the script:
#!/bin/bash
SCRIPT_DIR=$(dirname $(readlink -f $0))
declare -a profiles_list=()
while [[ "$1" != "" ]]
do
profiles_list+=($1)
shift
done
if [[ ${#profiles_list[@]} -eq 0 ]]
then
profiles_list+=("TERM_DEFAULT")
fi
TERM_LIST_PARAM=""
for profile in ${profiles_list[@]}
do
file="${SCRIPT_DIR}/${profile}.tabs"
if [[ ! -f $file ]]
then
echo $file does not exists
fi
while read tab
do
tab_line="--tab --working-directory='${tab}'"
TERM_LIST_PARAM="$tab_line $TERM_LIST_PARAM"
done < $file
done
echo gnome-terminal ${TERM_LIST_PARAM}
gnome-terminal -v ${TERM_LIST_PARAM}
echo $?
exit 0
|
Use arrays for storing separate arguments. Using strings makes the shell confused when it later tries to split them up on whitespaces.
TERM_LIST_PARAM=( )
Followed by,
tab_line=( --tab --working-directory="$tab" )
TERM_LIST_PARAM=( "${tab_line[@]}" "${TERM_LIST_PARAM[@]}" ) # or: TERM_LIST_PARAM+=( "${tab_line[@]}" )
Then,
gnome-terminal -v "${TERM_LIST_PARAM[@]}"
Additionally, you must double quote $0, $1, $file, and ${profiles_list[@]} in your code, or you'll run into issues as soon as any of these values contains spaces and/or globbing characters.

I currently work in hardware development, at present frequently connecting/disconnecting/rebooting device(s) connected to the serial ports. (Usually just /dev/ttyUSB0)
I have a basic script to monitor the serial port, which runs in its own small gnome-terminal window in one corner of my screen, so I can "at-a-glance" easily see if a device is connected, or has finished rebooting etc. This window is visble all the time. for monitoring purposes.
The script (monitorSerialPorts) is basic but functional:
while [ true ]
do
clear
printf "\n Serial Devices: "
ls /dev/ttyUSB* 2> /dev/null || (clear ; printf "\n No Devices Detected")
sleep 2
done
And I call this script from a second script (monitorSerialPortsLauncher), that runs upon login, the contents is just one line, which creates a small window nicely where I need it:
gnome-terminal --window-with-profile=RedonYellow --command=$HOME/scripts/monitorSerialPorts --geometry=26x3-20
Question: is there a clean way to combine this functionality in to a single script?
(Also, any overall suggestions for improvements to this process or script are welcomed)

You can put in this script in your monitorSerialPortsLauncher
#!/usr/bin/env bash
script=/tmp/monitorSerialPorts
cat << 'EOF' > $script
#!/usr/bin/env bash

do

I'm using Gnome 3.30 and beyond org.gnome.Terminal.desktop, I have two additional .desktop files with Exec=gnome-terminal --window-with-profile=XXX, where profile XXX uses custom command ssh kalle@XXX, so I can easily open terminals to work on my other machines.
What I don't like, especially when working with multiple terminal windows for each of the local and the other machines, is the fact that all windows are associated with the icon of org.gnome.Terminal.desktop.
Is there a way to get each window associated with the icon it belongs to?
BTW: I had the same issue when I started using an Eclipse version that was still under development. To be safe, I kept the previous, stable version and created another .desktop file for the new one. When I started both to copy and paste the software sites from the old to the new one, both windows were associated with the icon of the old one, although, as opposed to the gnome-terminal issue, these were different applications. Even renaming one of the two executables didn't change anything.
|
I found a solution. Since 'org.gnome.Terminal' sounds like a D-Bus service name, I took a look at the syslog after opening a terminal. The important part is:
dbus-daemon: Activating via systemd: service name='org.gnome.Terminal' unit='gnome-terminal-server.service'
I speculated that creating a new service with name 'org.gnome.Terminal.XXX' and renaming the .desktop file for machine XXX to 'org.gnome.Terminal.XXX.desktop' would do the trick, but in fact, the name of the .desktop file doesn't matter. The steps are as follows:
Create new D-Bus service
sudo cp /usr/share/dbus-1/services/org.gnome.Terminal{,.XXX}.service
Modify entries
Name=org.gnome.Terminal.XXX
SystemdService=gnome-terminal-server-XXX.service
Exec=/usr/lib/gnome-terminal/gnome-terminal-server --app-id org.gnome.Terminal.XXX
Create new Systemd unit
sudo cp /usr/lib/systemd/user/gnome-terminal-server{,-XXX}.service
Modify entries
Description=GNOME Terminal Server XXX
BusName=org.gnome.Terminal.XXX
ExecStart=/usr/lib/gnome-terminal/gnome-terminal-server --app-id org.gnome.Terminal.XXX
Update .desktop file
Exec=gnome-terminal --window-with-profile=XXX --app-id org.gnome.Terminal.XXX
The --app-id option is crucial for our service name to be used instead of the built-in one.

Backstory: I'm working with a piece of software that uses CMake for several build options. On my desktop build system when I execute a 'Processor Reset' command the program exits cleanly, but needs restarted with a different set of parameters. (The functionality works correctly on hardware, so I do not wish to modify the underlying source whatsoever.)
Question: My question is, how can I monitor the terminal output from the program, and upon seeing "Processor Reset Received", trigger a new instance of the program?
Caveats
My preferred answer would perform this in a shell script, but I'm open to other ideas.
I do not wish for there to be any recursion.
General Flow
Start the program with a Power-On Reset
./program -PO
(Program runs and prints output to terminal)
Send a Processor Reset Command
Program receives Processor Reset Command, prints relevant information, and terminates
Monitor program reads that the original program has terminates with a Processor Reset, and runs the program again with different flags.
./program -PR
Things I've tried
I have a partially working solution that... is interesting. It appears that there is some weird buffering going on which I've tried to disable, albeit unsuccessfully. But - it does successfully parse the program's terminal output and execute the Processor Reset flags when necessary (albeit once, as it is not in a loop.)
stdbuf -o0 -i0 -e0 sudo ./program -PO | tee /dev/tty | (grep "Processor Reset.") | (read && sudo ./program -PR)
To recap
I need the code to not buffer large chunks of data (i.e. write smoothly as it produces output)
It should be wrapped in a loop to allow multiple Processor Resets. (Any other reset should terminate the loop.)
|
Thanks to slm for pointing me in the right direction!
# Start the program with Power-On Reset
# Use tee to print output to terminal and pipe to grep
# grep returns 0 if the string is found
sudo ./program -PO | tee /dev/tty | grep -q "Processor Reset."
# Store the grep exit code in a variable
result="$?"
# If result is 0, grep found the Processor Reset string
if [ "$result" == "0" ]; then
while : ; do
sudo ./program -PR | tee /dev/tty | grep -q "Processor Reset."
result="$?"
# This loop will continue as long as the Processor Reset string is found
# once the program terminates
[ "$result" == "0" ] || break

Eve though in dconf the profiles i installed are shown
> dconf list /org/gnome/terminal/legacy/profiles:/

default
list
In my terminal preferences they are not shown so that i can change the profile
How can i resolve this issue, also i must say that i changed the curent value of profile in the dconf editor as another profile but still nothing in effect.
Also i must say that after i manually add profiles with the '+' button in the terminal preferences, if i add a new profile with "gogh" all the profiles i created manually are deleted, just the default profile left.
|
Okay i found a solution. The problem was with the wrong uuid format like @egmont said. The solution was to export the profiles with dconf dump from another working machine and get the right uuid, than importing those profiles with dconf load. After that i just added those uuids in the /profiles:/list. Ant there was the profiles in the preferences. Thanks for all the replies

I just checked my timings: it takes about 0.41-0.45 seconds to open a new gnome-terminal window and about 0.55-0.65 seconds to open kitty. And it does bother me a bit that it takes so much time to open (I want it to be close to instant, like UI elements are responding to mouse/keyboard events). I want some suggestions for either speeding up window open process or some terminal alternatives that open faster (I use kitty for several years now). Maybe someone can share their timings, so I can compare mine to something (I didn't find anything about this issue on the Internet).
Here's a MWE:
terminal=kitty # gnome-terminal
date +%s.%N > .start; $terminal -- sh -c 'echo "$(date +%s.%N)-$(cat .start)" | bc | cut -c 2- > .diff; rm -f .start'; cat .diff; rm -f .diff
My config: Laptop with i7-8550U, SSD, Ubuntu 20.04.
P.S. I'm hoping soon to hop to Pop!_OS 22.04. After that, I'll check my timings again (perhaps they'll improve).
Update:
Tried with zero config using root:
kitty: 0.38-0.43 seconds
gnome-terminal: 0.41-0.46 seconds
Update 2:
Run ranger using kitty with root (0 conf.) and alacritty (cargo crate is user-wide; 0 conf.):
kitty: 0.50-0.57 seconds
alacritty: 0.37-0.43 seconds
alacritty without ranger: 0.22-0.28 seconds (now we're talking)
kitty:
date +%s.%N > .start; kitty ranger --cmd 'shell echo "$(date +%%s.%N)-$(cat .start)" | bc | cut -c 2- > .diff; rm -f .start; kill $PPID'; cat .diff; rm -f .diff
alacritty:
date +%s.%N > .start; alacritty -e ranger --cmd 'shell echo "$(date +%%s.%N)-$(cat .start)" | bc | cut -c 2- > .diff; rm -f .start; kill $PPID'; cat .diff; rm -f .diff
P.S. I use ranger a lot (want to switch to lf) and 99% I open it with a shortcut bound to kitty ranger command.

I found out that only kitty (among those who I tested) can support ligatures. And looking at how it improves, I don't think anything can substitute it for me. And after some research, I found that (probably on a lot more speedy PC) some people manage to open kitty in 0.2s (0.1s to load OpenGL and 0.1s for the rest). Also, I fortunately found that kitty does support "server-client" architecture. You can create any number of groups in which terminals share some stuff (I don't have any specifics). And to create "the main" (the easiest) group, I only had to add 3 more chars: kitty -1:
--single-instance, -1
If specified only a single instance of kitty will run. New invocations
will instead create a new top-level window in the existing kitty
instance. This allows kitty to share a single sprite cache on the GPU
and also reduces startup time. You can also have separate groups of
kitty instances by using the --instance-group option.
Now the terminal (fully customized) opens in less than 0.2s (0.16-0.18)! That's 0.4s or 3.3 times faster than my first timings. It's about as fast as other server terminals (gnome-terminal, xfce4-terminal). There are only 2 downsides:
I don't think there's a way to run server in background, therefore 1st terminal opens with regular speed (0.57s);
If you kill one terminal (maybe something did freeze) — the other ones all go with it.
But currently I think these things aren't an issue for me and I probably can live with them. I installed Pop!_OS 22.04 and the UI is super responsive (I really think it will decrease the time even further).

I am trying to create a bash script that will set up my all development stuff in an instant.
What I want the script to do: open 5 different tabs in one window.
clear terminal and start firefox-esr.
clear terminal and run top command.
clear terminal and start development server by using npm live-server.
edit a file by using vim.
for testing purpose only.
Here is what I have so far:
#!/bin/sh
qterminal --tab
#clear && top
When I try to open new tab using command I got this error:

I just end up by installing gnome-terminal and remove qterminal.

gnome-terminal --tab --hide-menubar --title="Side Js" --working-directory ~/workshop/methodTwo/reference/reactMainConcepts/ -- vim
clear && top
And i added this in ~/.bashrc
# function to set terminal title
function setTitle() {
if [[ -z "$ORIG" ]]; then
ORIG=$PS1
fi
TITLE="\[\e]2;$*\a\]"
PS1=${ORIG}${TITLE}
#askUser
}
setTitle Testing
function askUser(){
~/workshop/devSetup.sh
}
setTitle function is not my own created function.
I copied it from this ask ubuntu answer.
Now i can use my development setup by using this command askUser.
If something is wrong in this answer please tell me it will fix it as soon as possible.

Is there any way to change Gnome-terminal settings, such as transparency, globally, so that I won't have to set it again and again after restarting i3-wm?

If anyone is interested, I've figured it out. Only thing you need to do is insert these two lines into your Xresources file:

I'm trying to change the color of "[shark@Archshark ~]$" to blue in the terminal but It seems that I can't change it, please help.
|
The prompt colour is governed by your shell configuration files. Assuming you use Bash, you can change the propmt colours in .bashrc or .bash_profile files in your home directory. I believe, judging by your prompt, you use Arch Linux, so you may find some information on prompt colours here.
For other common shells, look here.

I am on several machines running Linux Mint 20.1 "Ulyssa" - Cinnamon (64-bit), link to web, with Bash 5.0.17 as my default shell.
Today, I decided I customize my prompt and window title of my terminal emulator, which is GNOME Terminal.
I've known from the past this can be done for example per user in their .bashrc file.
As every computer has only one user + root, I went this way, I carefully read every line, to be honest, changed comments mostly.
I managed to identify and change colors to my liking. Also, the spacing where I wanted.
Relevant PS1 lines:
# Prompt:
# user @ host : full_path
if [ "$color_prompt" = yes ]; then
PS1='${debian_chroot:+($debian_chroot)}\[\033[01;32m\]\u \[\033[00m\]@ \[\033[01;34m\]\h\[\033[00m\] : ${PWD} \$ '
else
PS1='${debian_chroot:+($debian_chroot)}\u @ \h : ${PWD} \$ '
fi
# Set the window title to the same as prompt
case "$TERM" in
xterm*|rxvt*) PS1="\[\e]0;${debian_chroot:+($debian_chroot)}\u @ \h : ${PWD} \a\]$PS1" ;;
*) ;;
esac
So, the only thing remaining, which I fail on for hours, is setting the Terminal window title caption, it seemingly works upon launch, but does not change if changing directory. My apologies if it is messed up. I just want it to show a full path (no tilde) wherever I am. Thank you.
Picture for the words (terminal title-bar caption not updating):
|
For a reason unknown to me, it was only necessary to escape the $ (dollar sign) in front of PWD in the window title definition on this one line:
xterm*|rxvt*) PS1="\[\e]0;${debian_chroot:+($debian_chroot)}\u @ \h : \$PWD \a\]$PS1" ;;
I tested it somewhat and now preparing to deploy it on all machines.

Looks like your profile is busted. Login under root and create a new user account. Copy/move your old data from the old user to the new one.
If you don't remember root password reboot and add init=/bin/bash as a kernel command line argument, issue passwd, set a new root password, run sync and then reboot.
Alternatively, do this in a terminal (granted you're in your user directory - check using pwd - you should see something like /home/username):
/bin/mkdir BACKUP
/bin/mv * .* BACKUP
/bin/cp -a /etc/skel/* .
Now you must be able to login into your graphical DEs.

I am unable to determine the cause of this, but the day prior when using su to enter my password for installing an application through the terminal, the authentication has been successful. So far, I am uncertain on how to resolve this issue. I use a Fedora 29 GNOME OS.

Password:
su: Authentication failure
|
The su command does not accept your password. You must use the target user's password, which in your example shown is the root password.
Are you perhaps muddling su with sudo, which does take your own password for authentication?

Whenever I open the (Gnome) terminal from my Fedora 26 system this line is being displayed first before the command prompt:
-bash: /home/kiran/AIPS/LOGIN.SH: No such file or directory
I understand that on each start up the terminal is trying to read the above mentioned file. I find this irritating. Why is this happening?
(PS: AIPS was a software I had installed previously. After installing it I was not being able to open the system settings. The installation was incorrectly overriding the system libraries and hence I removed it. This warning that I am getting seems to be an artifact from that AIPS installation)
|
Based on one person's installation guide I suspect you have an AIPS-related line in your ~/.bashrc file; edit that file and remove the line that reads something like:
. ~/AIPS/LOGIN.SH
It could use variations such as:
source ~/AIPS/LOGIN.SH
or
source $HOME/AIPS/LOGIN.SH
Search for the text AIPS/LOGIN.SH and you should find the right spot.

i want to open a new terminal and execute a script immediately to it (to set a title in the new tab) and i cannot configure this. I try:
gnome-terminal --tab-with-profile=$varname -x ./test.sh -c "script -a -c 'ping $varname' $PATH_REPORT/$varname.log"
Any help how can i execute the test.sh script which contains:
PROMPT_COMMAND='echo -ne "\033]0;${varname}\007"'
with the others in command i wrote?
|
You can simplify your solution so that you only need to specify the hostname once. The test.sh script can set the prompt directly with the echo command and then run the ping you want.
$ cat test.sh
#!/bin/bash
echo -ne "\033]0;$1\007"
script -a -c "ping $1" $PATH_REPORT/$1.log
Now you can call this with
gnome-terminal -x ./test.sh $varname
(make sure PATH_REPORT is set in the script before hand,or exported from the current shell)
If you want more complicated executions then you can adjust the test.sh script as you need.

I'm new to scripting, but somewhat familiar with Linux. I am actually using this on a Fedora16 build, with Gnome3 and gnome-terminal... fyi.
I flip through all sorts of ssh terminals all day long and I thought it would be nice to create a ssh script called lambda that contains information that is sent to a terminal_wrapper script that accepts all sorts of variables and creates a new gnome-terminal based on those given variables. The information I would like would be to rename the title, change bg and fg colors, and start an ssh in a new gnome-terminal window.
I feel like I'm close to getting the ssh to work, but I'm missing something. Here is what I've got for my ssh script for lambda:
terminal_wrapper user lambda.company.com
And here is my terminal_wrapper:
gnome-terminal --title=$2 -e ssh $1 $2
It opens a new window for me, renames it to the lambda.company.com, and then sits there and closes after a second.
Any help? Thanks.

I would like to capture the stdout (as sent to a terminal), and perform some processing after it is output on the terminal (for the user).
I want to know how to grab the output, process and make changes accordingly.
(If possible) I want this to happen for every command I type on the terminal.
Edit: After a dialogue in a temporary chat forum it was clear that
we should
both look for which commands are issued
and what output there is from the commands and
do something, if a particular command or output is detected.
|
Well, maybe it is not a good idea to grab the output, process and display the output of every command you type on the terminal.
But you can do it for some particular command via tee
your-command | tee saved-output | processing-tool
When you have seen the result from the processing-tool, you can look at the saved-output for example with cat (if short output) or less (if long output).
Example:
$ LANG=C sudo lshw | tee saved-output | grep -i -A2 disk
*-disk
description: ATA Disk
product: KINGSTON SKC300S
physical id: 0.0.0
--
*-disk
description: ATA Disk
product: WDC WD4002FYYZ-0
vendor: Western Digital
$ less saved-output
After a dialogue in a temporary chat forum , I suggest to
try vialog or viafifo according to the following links
maybe modify one of them to do what is expected in this case,
both look for which commands are issued
and what output there is from the commands and
do something, if a particular command or output is detected.
Send a notification or alert when bash asks for input from user
This link to AskUbuntu
It works directly to use vialog like the following example.
vialog 2>&1 | tee saved-output | grep 'docker container ls' && echo 'it was mentioned'
In the real case, I think you would like to start something more advanced than echo 'it was mentioned', but this is only a demo example. And things can be more efficient, if you build the specific checks into vialog and disable the alerts, that are probably not necessary in your case.
Screenshot during the dialogue:
Screenshot after the dialogue:
This way you can easily check if a command that is called is not found:
$ LANGUAGE=C vialog 2>&1 | tee saved-output | grep -i 'Command.*not found' && echo 'it was mentioned'
Command 'docker' not found, but can be installed with:
it was mentioned
$ cat saved-output
----- start vialog at 2019-01-12 18:57:33 ----------------------------
$ docker container ls

$ exit

I have written a shell script named startup.sh which does a lot of things (basically start a lot of things for me after turning on my local machine) - here is an excerpt:
#!/bin/bash

veracrypt --auto-mount favorites &
thunderbird &
~/Application/IDEA/bin/./idea.sh &
/usr/bin/slack &
echo myuser mypass | skypeforlinux --pipelogin &
sh bsync-project-folder.sh &
exit
Open a console window and do:
. startup.sh
The shell script is executed and the window is closed afterwards.
Also working:
sh startup.sh
OR
./startup.sh
The shell script is executed and the terminal window stays open - however it does not return to the console and have to stop script execution with CTRL + C (no matter if I execute with the command line interpreter or with ./).
However I want a clean exit of my script and then return to the same console with a success message. What am I missing?
|
When you start a script with '< dot> < space> < script_name>' and you have in your script "exit", your window will be closed. The dot notation means you run it within the window and then the "exit" means to exit the window, not the script itself.
Try to add >/dev/null 2>&1 to each of the line (before final &) to find out which of the commands still holds stdout, eg.:
gnome-terminal --tab >/dev/null 2>&1 &
...
you may but need not to leave the exit at the end but it does not have any sense here.
Run the script: ./startup.sh

When I open gnome-terminal, instead of presenting me with my default Bash shell, it shows:
sh-4.4$
This began happening since I added DISPLAY=:0 to my crontab -e file which now looks as follows:
DISPLAY=:0
0 0,6,12,18 * * * /usr/bin/gnome-terminal -e /home/orschiro/bin/updates.sh
0 0,6,12,18 * * * /usr/bin/gnome-terminal -e /home/orschiro/bin/rclone.sh
And also of interest:
sh-4.4$ ls -l /bin/sh
lrwxrwxrwx. 1 root root 4 18. Jun 10:30 /bin/sh -> bash
|
I'm assuming this is the gnome-terminal started from your cronjob.
There is absolutely no need to run the cronjob scripts inside gnome-terminal. Doing so would mean that the jobs would fail if gnome-terminal could not be opened (which would probably happen if you weren't using the desktop at the time).
Just use
0 0,6,12,18 * * * "$HOME"/bin/updates.sh
0 0,6,12,18 * * * "$HOME"/bin/rclone.sh
Any output from the scripts will be emailed to you, assuming local email delivery was enabled. To save the output to a log file, use a redirection:
0 0,6,12,18 * * * "$HOME"/bin/updates.sh >>"$HOME"/updates.log"
0 0,6,12,18 * * * "$HOME"/bin/rclone.sh >>"$HOME"/rclone.log"
The environment that the cronjobs are running in is different from the one you usually have when logged in through a graphical desktop environment. For one thing, your default shell may not be set in the SHELL environment variable, which is why gnome-terminal starts /bin/sh instead of bash (sh is bash on your system, but runs in POSIX compatibility mode when invoked as sh).
When logged in on the graphical desktop environment, opening gnome-terminal as usual would give you your default shell. If it doesn't, it's because there's a gnome-terminal-server process running which was started by the cron jobs. Terminate this process by either rebooting or by using pkill -f gnome-terminal-server.

I use screen for my command-line tasks while managing the servers where I work. I usually run small commands (mostly file-system tasks) but sometimes I run more extensive tasks (like DBA).
The output of those tasks is important to me. Since I use Ubuntu and OS X (both Terminal Windows) for my tasks, yet I need to use screen, the scrolling is not available, so any long output (think a 500-row table from a select) is invisible for me. Mouse-wheel is out of the question.
When I say "scroll is invisible for me, I mean this:
I was thinking about two options:
Pause (think paginate) the output of a certain command. When the output begins, it would let me read what's happening, then I press "Enter", then the output continues until there's nothing more to show.
Scroll inside screen. But I don't know if this is possible.
Of course, I don't know if those options are actually possible. If they are, how can achieve them? Other alternatives will be well received.
|
Screen has its own scroll buffer, as it is a terminal multiplexer and has to deal with several buffers.
Maybe there's a better way, but I'm used to scrolling using the "copy mode" (which you can use to copy text using screen itself, although that requires the paste command too):
Hit your screen prefix combination (C-a / control+A by default), then hit Escape or [.
Move up and down with the arrow keys (↑ and ↓).
When you're done, hit any key except arrow keys, numbers, and certain letters to get back to the end of the scroll buffer. Most people use q or Escape
(If instead of exiting you press Enter or Space and then move the cursor, you will start selecting text to copy, and pressing Enter or Space a second time will copy it. Then you can paste with C-a followed by ].)
Of course, you can always use more and less, two commonly used pagers, which may be enough for some commands.

From vi, if you issue the command :sp, the screen splits into two "views", allowing you to edit more than one file from the same terminal.
Along those same lines, is there a way to have multiple shells open in the same terminal?
|
You can do it in screen the terminal multiplexer.
To split vertically: ctrla then |.
To split horizontally: ctrla then S (uppercase 's').
To unsplit: ctrla then Q (uppercase 'q').
To switch from one to the other: ctrla then tab
Note: After splitting, you need to go into the new region and start a new session via ctrla then c before you can use that area.
EDIT, basic screen usage:
New terminal: ctrla then c.
Next terminal: ctrla then space.
Previous terminal: ctrla then backspace.
N'th terminal ctrla then [n]. (works for n∈{0,1…9})
Switch between terminals using list: ctrla then " (useful when more than 10 terminals)
Send ctrla to the underlying terminal ctrla then a.

The session is still attached on another terminal. The server hasn't detected the network outage on that connection: it only detects the outage when it tries to send a packet and gets an error back or no response after a timeout, but this hasn't happened yet. You're in a common situation where the client detected the outage because it tried to send some input and failed, but the server is just sitting there waiting for input. Eventually the server will send a keepalive packet and detect that the connection is dead.
In the meantime, use the -d option to detach the screen session from the terminal where it's in.
screen -r -d 30608
screen -rd is pretty much the standard way to attach to an existing screen session.

Browsing through questions I found about tmux (I normally used GNU Screen). My question is what are pros and cons of each of them. Especially I couldn't find much about tmux.
|
From their website:
How is tmux different from GNU screen? What else does it offer?
tmux offers several advantages over screen:
a clearly-defined client-server model: windows are independent entities which
may be attached simultaneously to multiple sessions and viewed from multiple
clients (terminals), as well as moved freely between sessions within the same
tmux server;
a consistent, well-documented command interface, with the same syntax
whether used interactively, as a key binding, or from the shell;
easily scriptable from the shell;
multiple paste buffers;
choice of vi or emacs key layouts;
an option to limit the window size;
a more usable status line syntax, with the ability to display the first line
of output of a specific command;
a cleaner, modern, easily extended, BSD-licensed codebase.
There are still a few features screen includes that tmux omits:
builtin serial and telnet support; this is bloat and is unlikely to be added
to tmux;
wider platform support, for example IRIX and HP-UX, and for odd terminals.

I have a running program on a SSH shell. I want to pause it and be able to unpause its execution when I come back.
One way I thought of doing that was to transfer its ownership to a screen shell, thus keeping it running in there.
Is there a different way to proceed?

You can revoke “ownership” of the program from the shell with the disown built-in:
# press Ctrl+Z to suspend the program
bg
disown
However this only tells the shell not to send a SIGHUP signal to the program when the shell exits. The program will retain any connection it has with the terminal, usually as standard input, output and error streams. There is no way to reattach those to another terminal. (Screen works by emulating a terminal for each window, so the programs are attached to the screen window.)
It is possible to reattach the filedescriptors to a different file by attaching the program in a debugger (i.e. using ptrace) and making it call open, dup and close. There are a few tools that do this; this is a tricky process, and sometimes they will crash the process instead. The possibilities include (links collected from answers to How can I disown a running process and associate it to a new screen shell? and Can I nohup/screen an already-started process?):
grab (and the more ambitious cryopid)
neercs
reredirect
reptyr

I accidentally created over 1000 screens. How do I kill them all with one command? (Or a few)
|
You can use :
pkill screen
Or
killall screen
In OSX the process is called SCREEN in all caps. So, use:
pkill SCREEN
Or
killall SCREEN

I've accidentally attached to a 2nd GNU screen session from within an existing screen session and cannot detach or issue commands to the inner screen. I remember figuring out how to do that before but completely forgot and would like to keep it as reference.
One way is to detach the inner screen by doing screen -dr from shell, but what is the key combination to do that from within screen itself?

ctrl-a a d

When I type screen -r I expect to either see: A list of screens to resume, or a message "There is no screen to be resumed."
Today, I see there is one screen, but I still get the message that there is no screen to be resumed:
[root@server chiliNUT]# screen -r
There is a screen on:
27863.pts-1.server (Attached)
There is no screen to be resumed.
[root@server chiliNUT]# screen -rx 27863
[detached]
[root@server chiliNUT]# screen -r
There is a screen on:
27863.pts-1.server (Attached)
There is no screen to be resumed.
Why is it reporting that the screen is attached? I just detached it on the line above ([detached])
|
As screen -r says, there is one screen, but it is attached. To resume it on your current terminal, you have to detach it from the other one first: screen -d -r 27863, see manpage -d.
Edit: use -d instead of -x.
Edit2: @alex78191: When using -x, screen attaches to the currently running session, resulting in a "multi-display mode": you see the session on both terminals simultaneously, i.e., when entering a command on one terminal, it also appears on the second. However, detaching from a multi-display mode just detaches the current terminal. You hence get the message that it is still attached (on the other terminal).
