Sep 19, 2025, 09:14 by [email protected]:Should I somehow *assume* that "--help" is supported?Actually, yes. If there is only one thing that you would reasonably assume about any command -- then this would be it. :-) When you encounter an unfamiliar command, you don't immediately rush to find its documentation -- No, you first try "--help" -- and that is a reasonable assumption.
Not all the world is Linux. $ /bin/cp --help /bin/cp: illegal option -- - usage: cp [-R [-H | -L | -P]] [-fi | -n] [-aclpSsvXx] source_file target_filecp [-R [-H | -L | -P]] [-fi | -n] [-aclpSsvXx] source_file ... target_directory
$ echo $?
