groups - print group membership of user
groups [user...]
The command groups prints on standard output the groups to
which you or the optionally specified user belong. Each user
belongs to a group specified in /etc/passwd and possibly to
other groups as specified in /etc/group. Note that
/etc/passwd specifies the numerical ID (gid) of the group.
The groups command converts gid to the group name in the
output.
The output takes the following form:
example% groups tester01 tester02
tester01 : staff
tester02 : staff
example%
/etc/passwd
/etc/group
