> one that customarily means "pass the rest of arguments on to a subprocess". It's convenient for passing options and args to a subprocess, but it customarily means "don't interpret anything following this as a short or long option, just as a positional argument". For example: touch -f # error touch -- -f # creates a file named "-f" rm * # oh crap we just passed "rm -f" a bunch of files rm -- * # don't treat that "-f" as an option, just delete the file named "-f"
