@vr-t8x15 There is no guarantee than a man is installed on a system with GNU coreutils installed, nor the packagers haven't decided to remove the manpages and add them to a -doc version of the package (that may not be installable if you don't have internet right then).

Meanwhile, those kind of packagers can't work out how to strip out gettext files usually.


For every binary on the system, unless there is a legitimate technical reason not to, the license should be printed when --version or --license is passed, preferably optionally in the users preferred native language.

The manpage is really for more detailed information on software usage and GNU has those too.
