I just gave the OP a command that works. I hadn't expected it to
kick off a discussion, nor to have to justify it. But:
axis!david 08:55:22 ~ $ grep -e '^adm' -e '^unlock' /etc/group
adm:x:4:david
unlock:x:1010:
axis!david 08:55:47 ~ $ grep -e '^adm' -e '^unlock' /etc/group
adm:x:4:david,unlock
unlock:x:1010:
axis!david 08:56:40 ~ $
axis 08:51:11 ~# addgroup unlock adm
Adding user `unlock' to group `adm' ...
Adding user unlock to group adm
Done.
axis 08:56:28 ~#
Or, if you prefer it in a time sequence:
axis!david 08:55:22 ~ $ grep -e '^adm' -e '^unlock' /etc/group
adm:x:4:david
unlock:x:1010:
axis!david 08:55:47 ~ $ grep -e '^adm' -e '^unlock' /etc/group
axis 08:51:11 ~# addgroup unlock adm
Adding user `unlock' to group `adm' ...
Adding user unlock to group adm
Done.
axis 08:56:28 ~#
axis!david 08:55:47 ~ $ grep -e '^adm' -e '^unlock' /etc/group
adm:x:4:david,unlock
unlock:x:1010:
axis!david 08:56:40 ~ $
Buried in there is "addgroup unlock adm", where adm is the well-known
group, and unlock is the user whose sole function is to lock and
unlock /home partitions on my systems.
Cheers,
David.
