groups(1) BSD General Commands Manual groups(1)
groups -- show group memberships
The groups utility has been obsoleted by the id(1) utility, and is equiv- alent to ``id -Gn [user]''. The command ``id -p'' is suggested for nor- mal interactive use. The groups utility displays the groups to which you (or the optionally specified user) belong.
The groups utility exits 0 on success, and >0 if an error occurs.
