One Day One GNU/Linux Command
=============================
chgrp -- CHange the GRouP ownership.
Summary :
`chgrp' changes the group ownership of each given file(s) to the
specified group (group name or a numeric group id).
Examples :
$ chgrp grp1 file1 -- Change the group ownership to grp1. No change in
the user ownership.
$ chgrp grp1 f1 f2 f3 -- Same as above, but for files f1, f2 and f3.
$ chgrp 400 file1 -- Change the group ownership to a group, GID:400.
$ chgrp -R grp1 dir1 -- Recursively change group ownership of Dir and
their contents.
$ chgrp -c grp1 f1 f2 f3 -- Show verbose output only when a change is
made.
$ chgrp -v grp1 f1 f2 f3 -- Show verbose output for every file
processed.
$ chgrp -f grp1 f1 f2 f3 -- Force/Silent/Quiet. Do not print error
messages.
$ chgrp -d grp1 f1 -- If f1 is symbolic link, then do not act on it.
But act on what they point to.
$ chgrp --reference=that this -- Set the 'that' file's group to 'this'.
Note: Instead of Group name, Group ID can be used.
$ echo $GROUPS -- Show Group ID.
Read : man chgrp
