I have a fresh Debian 8.1 installation and am trying to make its usability feel like OSX.
I run
xelatex document.tex && evince document.pdf &
but it only successfully runs xelatex and does not update the PDF document in the viewer which is already open.
How can I make evince fetch the updated document from the disk... |
Evince is updating the pdf automatically. No need to restart it. At least mine does on Debian 8.1.
When it's not reloading automatically anymore, maybe you ran out of inotify watches. Increase it with:

I've been having trouble researching this topic so I'm hoping someone can point me in the right direction. Are there any Kernel configurations required to be enabled in the OS for Inotify to work? What options do I need to enable in the .config file of Linux kernel?

Yes, CONFIG_INOTIFY_USER. Here's the help text associated with that kernel option:

There are many ways to go about this.
Method #1 - ps
You can use the ps command to find the process ID for this process and then use the PID to kill the process.

You can revoke “ownership” of the program from the shell with the disown built-in:

I think you may be confused about the job control notation.
