Output:
Usage: od [OPTION]... [FILE]...
  or:  od [-abcdfilosx]... [FILE] [[+]OFFSET[.][b]]
  or:  od --traditional [OPTION]... [FILE] [[+]OFFSET[.][b] [+][LABEL][.][b]]

Write an unambiguous representation, octal bytes by default,
of FILE to standard output.  With more than one FILE argument,
concatenate them in the listed order to form the input.

With no FILE, or when FILE is -, read standard input.

If first and second call formats both apply, the second format is assumed
if the last operand begins with + or (if there are 2 operands) a digit.
An OFFSET operand means -j OFFSET.  LABEL is the pseudo-address
at first byte printed, incremented when dump is progressing.
For OFFSET and LABEL, a 0x or 0X prefix indicates hexadecimal;
suffixes may be . for octal and b for multiply by 512.

Mandatory arguments to long options are mandatory for short options too.
  -A, --address-radix=RADIX   output format for file offsets; RADIX is one
                                of [doxn], for Decimal, Octal, Hex or None
      --endian={big|little}   swap input bytes according the specified order
  -j, --skip-bytes=BYTES      skip BYTES input bytes first
  -N, --read-bytes=BYTES      limit dump to BYTES input bytes
  -S BYTES, --strings[=BYTES]  show only NUL terminated strings
                                of at least BYTES (3) printable characters
  -t, --format=TYPE           select output format or formats
  -v, --output-duplicates     do not use * to mark line suppression
  -w[BYTES], --width[=BYTES]  output BYTES bytes per output line;
                                32 is implied when BYTES is not specified
      --traditional           accept arguments in third form above
      --help        display this help and exit
      --version     output version information and exit

Traditional format specifications may be intermixed; they accumulate:
  -a   same as -t a,  select named characters, ignoring high-order bit
  -b   same as -t o1, select octal bytes
  -c   same as -t c,  select printable characters or backslash escapes
  -d   same as -t u2, select unsigned decimal 2-byte units
  -f   same as -t fF, select floats
  -i   same as -t dI, select decimal ints
  -l   same as -t dL, select decimal longs
  -o   same as -t o2, select octal 2-byte units
  -s   same as -t d2, select decimal 2-byte units
  -x   same as -t x2, select hexadecimal 2-byte units

TYPE is made up of one or more of these specifications:
  a          named character, ignoring high-order bit
  c          printable character or backslash escape
  d[SIZE]    signed decimal, SIZE bytes per integer
  f[SIZE]    floating point, SIZE bytes per float
  o[SIZE]    octal, SIZE bytes per integer
  u[SIZE]    unsigned decimal, SIZE bytes per integer
  x[SIZE]    hexadecimal, SIZE bytes per integer

SIZE is a number.  For TYPE in [doux], SIZE may also be C for
sizeof(char), S for sizeof(short), I for sizeof(int) or L for
sizeof(long).  If TYPE is f, SIZE may also be F for sizeof(float), D
for sizeof(double) or L for sizeof(long double).

Adding a z suffix to any type displays printable characters at the end of
each output line.

BYTES is hex with 0x or 0X prefix, and may have a multiplier suffix:
  b    512
  KB   1000
  K    1024
  MB   1000*1000
  M    1024*1024
and so on for G, T, P, E, Z, Y, R, Q.
Binary prefixes can be used, too: KiB=K, MiB=M, and so on.

Usage: ln [OPTION]... [-T] TARGET LINK_NAME
  or:  ln [OPTION]... TARGET
  or:  ln [OPTION]... TARGET... DIRECTORY
  or:  ln [OPTION]... -t DIRECTORY TARGET...
In the 1st form, create a link to TARGET with the name LINK_NAME.
In the 2nd form, create a link to TARGET in the current directory.
In the 3rd and 4th forms, create links to each TARGET in DIRECTORY.
Create hard links by default, symbolic links with --symbolic.
By default, each destination (name of new link) should not already exist.
When creating hard links, each TARGET must exist.  Symbolic links
can hold arbitrary text; if later resolved, a relative link is
interpreted in relation to its parent directory.

Mandatory arguments to long options are mandatory for short options too.
      --backup[=CONTROL]      make a backup of each existing destination file
  -b                          like --backup but does not accept an argument
  -d, -F, --directory         allow the superuser to attempt to hard link
                                directories (note: will probably fail due to
                                system restrictions, even for the superuser)
  -f, --force                 remove existing destination files
  -i, --interactive           prompt whether to remove destinations
  -L, --logical               dereference TARGETs that are symbolic links
  -n, --no-dereference        treat LINK_NAME as a normal file if
                                it is a symbolic link to a directory
  -P, --physical              make hard links directly to symbolic links
  -r, --relative              with -s, create links relative to link location
  -s, --symbolic              make symbolic links instead of hard links
  -S, --suffix=SUFFIX         override the usual backup suffix
  -t, --target-directory=DIRECTORY  specify the DIRECTORY in which to create
                                the links
  -T, --no-target-directory   treat LINK_NAME as a normal file always
  -v, --verbose               print name of each linked file
      --help        display this help and exit
      --version     output version information and exit

The backup suffix is '~', unless set with --suffix or SIMPLE_BACKUP_SUFFIX.
The version control method may be selected via the --backup option or through
the VERSION_CONTROL environment variable.  Here are the values:

  none, off       never make backups (even if --backup is given)
  numbered, t     make numbered backups
  existing, nil   numbered if numbered backups exist, simple otherwise
  simple, never   always make simple backups

Using -s ignores -L and -P.  Otherwise, the last option specified controls
behavior when a TARGET is a symbolic link, defaulting to -P.

Input: chown --help root:sudo .bash_logout

Output:
Usage: chown [OPTION]... [OWNER][:[GROUP]] FILE...
  or:  chown [OPTION]... --reference=RFILE FILE...
Change the owner and/or group of each FILE to OWNER and/or GROUP.
With --reference, change the owner and group of each FILE to those of RFILE.

  -c, --changes          like verbose but report only when a change is made
  -f, --silent, --quiet  suppress most error messages
  -v, --verbose          output a diagnostic for every file processed
      --dereference      affect the referent of each symbolic link (this is
                         the default), rather than the symbolic link itself
  -h, --no-dereference   affect symbolic links instead of any referenced file
                         (useful only on systems that can change the
                         ownership of a symlink)
      --from=CURRENT_OWNER:CURRENT_GROUP
                         change the owner and/or group of each file only if
                         its current owner and/or group match those specified
                         here.  Either may be omitted, in which case a match
                         is not required for the omitted attribute
      --no-preserve-root  do not treat '/' specially (the default)
      --preserve-root    fail to operate recursively on '/'
      --reference=RFILE  use RFILE's owner and group rather than specifying
                         OWNER:GROUP values.  RFILE is always dereferenced.
  -R, --recursive        operate on files and directories recursively

The following options modify how a hierarchy is traversed when the -R
option is also specified.  If more than one is specified, only the final
one takes effect.

  -H                     if a command line argument is a symbolic link
                         to a directory, traverse it
  -L                     traverse every symbolic link to a directory
                         encountered
  -P                     do not traverse any symbolic links (default)

      --help        display this help and exit
      --version     output version information and exit

Owner is unchanged if missing.  Group is unchanged if missing, but changed
to login group if implied by a ':' following a symbolic OWNER.
OWNER and GROUP may be numeric as well as symbolic.

Examples:
  chown root /u        Change the owner of /u to "root".
  chown root:staff /u  Likewise, but also change its group to "staff".
  chown -hR root /u    Change the owner of /u and subfiles to "root".

Output:
cd: cd [-L|[-P [-e]] [-@]] [dir]
    Change the shell working directory.

    Change the current directory to DIR.  The default DIR is the value of the
    HOME shell variable. If DIR is "-", it is converted to $OLDPWD.

    The variable CDPATH defines the search path for the directory containing
    DIR.  Alternative directory names in CDPATH are separated by a colon (:).
    A null directory name is the same as the current directory.  If DIR begins
    with a slash (/), then CDPATH is not used.

    If the directory is not found, and the shell option `cdable_vars' is set,
    the word is assumed to be  a variable name.  If that variable has a value,
    its value is used for DIR.

    Options:
      -L	force symbolic links to be followed: resolve symbolic
    		links in DIR after processing instances of `..'
      -P	use the physical directory structure without following
    		symbolic links: resolve symbolic links in DIR before
    		processing instances of `..'
      -e	if the -P option is supplied, and the current working
    		directory cannot be determined successfully, exit with
    		a non-zero status
      -@	on systems that support it, present a file with extended
    		attributes as a directory containing the file attributes

    The default is to follow symbolic links, as if `-L' were specified.
    `..' is processed by removing the immediately previous pathname component
    back to a slash or the beginning of DIR.

    Exit Status:
    Returns 0 if the directory is changed, and if $PWD is set successfully when
    -P is used; non-zero otherwise.

Usage: od [OPTION]... [FILE]...
  or:  od [-abcdfilosx]... [FILE] [[+]OFFSET[.][b]]
  or:  od --traditional [OPTION]... [FILE] [[+]OFFSET[.][b] [+][LABEL][.][b]]

Write an unambiguous representation, octal bytes by default,
of FILE to standard output.  With more than one FILE argument,
concatenate them in the listed order to form the input.

With no FILE, or when FILE is -, read standard input.

If first and second call formats both apply, the second format is assumed
if the last operand begins with + or (if there are 2 operands) a digit.
An OFFSET operand means -j OFFSET.  LABEL is the pseudo-address
at first byte printed, incremented when dump is progressing.
For OFFSET and LABEL, a 0x or 0X prefix indicates hexadecimal;
suffixes may be . for octal and b for multiply by 512.

Mandatory arguments to long options are mandatory for short options too.
  -A, --address-radix=RADIX   output format for file offsets; RADIX is one
                                of [doxn], for Decimal, Octal, Hex or None
      --endian={big|little}   swap input bytes according the specified order
  -j, --skip-bytes=BYTES      skip BYTES input bytes first
  -N, --read-bytes=BYTES      limit dump to BYTES input bytes
  -S BYTES, --strings[=BYTES]  show only NUL terminated strings
                                of at least BYTES (3) printable characters
  -t, --format=TYPE           select output format or formats
  -v, --output-duplicates     do not use * to mark line suppression
  -w[BYTES], --width[=BYTES]  output BYTES bytes per output line;
                                32 is implied when BYTES is not specified
      --traditional           accept arguments in third form above
      --help        display this help and exit
      --version     output version information and exit

Traditional format specifications may be intermixed; they accumulate:
  -a   same as -t a,  select named characters, ignoring high-order bit
  -b   same as -t o1, select octal bytes
  -c   same as -t c,  select printable characters or backslash escapes
  -d   same as -t u2, select unsigned decimal 2-byte units
  -f   same as -t fF, select floats
  -i   same as -t dI, select decimal ints
  -l   same as -t dL, select decimal longs
  -o   same as -t o2, select octal 2-byte units
  -s   same as -t d2, select decimal 2-byte units
  -x   same as -t x2, select hexadecimal 2-byte units

TYPE is made up of one or more of these specifications:
  a          named character, ignoring high-order bit
  c          printable character or backslash escape
  d[SIZE]    signed decimal, SIZE bytes per integer
  f[SIZE]    floating point, SIZE bytes per float
  o[SIZE]    octal, SIZE bytes per integer
  u[SIZE]    unsigned decimal, SIZE bytes per integer
  x[SIZE]    hexadecimal, SIZE bytes per integer

SIZE is a number.  For TYPE in [doux], SIZE may also be C for
sizeof(char), S for sizeof(short), I for sizeof(int) or L for
sizeof(long).  If TYPE is f, SIZE may also be F for sizeof(float), D
for sizeof(double) or L for sizeof(long double).

Adding a z suffix to any type displays printable characters at the end of
each output line.

BYTES is hex with 0x or 0X prefix, and may have a multiplier suffix:
  b    512
  KB   1000
  K    1024
  MB   1000*1000
  M    1024*1024
and so on for G, T, P, E, Z, Y, R, Q.
Binary prefixes can be used, too: KiB=K, MiB=M, and so on.

    Modify shell resource limits.

    Provides control over the resources available to the shell and processes
    it creates, on systems that allow such control.

    Options:
      -S	use the `soft' resource limit
      -H	use the `hard' resource limit
      -a	all current limits are reported
      -b	the socket buffer size
      -c	the maximum size of core files created
      -d	the maximum size of a process's data segment
      -e	the maximum scheduling priority (`nice')
      -f	the maximum size of files written by the shell and its children
      -i	the maximum number of pending signals
      -k	the maximum number of kqueues allocated for this process
      -l	the maximum size a process may lock into memory
      -m	the maximum resident set size
      -n	the maximum number of open file descriptors
      -p	the pipe buffer size
      -q	the maximum number of bytes in POSIX message queues
      -r	the maximum real-time scheduling priority
      -s	the maximum stack size
      -t	the maximum amount of cpu time in seconds
      -u	the maximum number of user processes
      -v	the size of virtual memory
      -x	the maximum number of file locks
      -P	the maximum number of pseudoterminals
      -R	the maximum time a real-time process can run before blocking
      -T	the maximum number of threads

    Not all options are available on all platforms.

    If LIMIT is given, it is the new value of the specified resource; the
    special LIMIT values `soft', `hard', and `unlimited' stand for the
    current soft limit, the current hard limit, and no limit, respectively.
    Otherwise, the current value of the specified resource is printed.  If
    no option is given, then -f is assumed.

    Values are in 1024-byte increments, except for -t, which is in seconds,
    -p, which is in increments of 512 bytes, and -u, which is an unscaled
    number of processes.

    Exit Status:
    Returns success unless an invalid option is supplied or an error occurs.

Input: nl --help -n ln -p --body-numbering=pBRE -pp -p /home/ubuntu/scripts/auto.tar.gz system_info.txt

Output:
Usage: nl [OPTION]... [FILE]...
Write each FILE to standard output, with line numbers added.

With no FILE, or when FILE is -, read standard input.

Mandatory arguments to long options are mandatory for short options too.
  -b, --body-numbering=STYLE      use STYLE for numbering body lines
  -d, --section-delimiter=CC      use CC for logical page delimiters
  -f, --footer-numbering=STYLE    use STYLE for numbering footer lines
  -h, --header-numbering=STYLE    use STYLE for numbering header lines
  -i, --line-increment=NUMBER     line number increment at each line
  -l, --join-blank-lines=NUMBER   group of NUMBER empty lines counted as one
  -n, --number-format=FORMAT      insert line numbers according to FORMAT
  -p, --no-renumber               do not reset line numbers for each section
  -s, --number-separator=STRING   add STRING after (possible) line number
  -v, --starting-line-number=NUMBER  first line number for each section
  -w, --number-width=NUMBER       use NUMBER columns for line numbers
      --help        display this help and exit
      --version     output version information and exit

Default options are: -bt -d'\:' -fn -hn -i1 -l1 -n'rn' -s<TAB> -v1 -w6

CC are two delimiter characters used to construct logical page delimiters;
a missing second character implies ':'.  As a GNU extension one can specify
more than two characters, and also specifying the empty string (-d '')
disables section matching.

STYLE is one of:

  a      number all lines
  t      number only nonempty lines
  n      number no lines
  pBRE   number only lines that contain a match for the basic regular
         expression, BRE

FORMAT is one of:

  ln     left justified, no leading zeros
  rn     right justified, no leading zeros
  rz     right justified, leading zeros

Output:
Usage: touch [OPTION]... FILE...
Update the access and modification times of each FILE to the current time.

A FILE argument that does not exist is created empty, unless -c or -h

A FILE argument string of - is handled specially and causes touch to
change the times of the file associated with standard output.

Mandatory arguments to long options are mandatory for short options too.

                         file (useful only on systems that can change the
                         timestamps of a symlink)

  -r, --reference=FILE   use this file's times instead of current time
  -t STAMP               use [[CC]YY]MMDDhhmm[.ss] instead of current time
      --time=WORD        change the specified time:
                           WORD is access, atime, or use: equivalent to -a
