Bash Command-Line Options

F.2. Bash Command-Line Options

Bash itself has a number of command-line options. Here are some of the more useful ones.

  • -c

    Read commands from the following string and assign any arguments to the positional parameters.

    bash$ bash -c 'set a b c d; IFS="+-;"; echo "$*"'
    a+b+c+d
    	      

  • -r

    --restricted

    Runs the shell, or a script, in restricted mode.

  • --posix

    Forces Bash to conform to POSIX mode.

  • --version

    Display Bash version information and exit.

  • --

    End of options. Anything further on the command line is an argument, not an option.
