How to list users groups

[Michael Campbell]

Quick question for someone

Does anyone know of a quick and easy way to list a user's primary and secondary groups (equivalent to the lsuser command on AIX)

Any Help Appreciated

Hi Michael,

id -gn

will list the primary group belongs to (brackets shall indicate required argument, not to be typed)

wheras

id -Gn

will list all the groups that account belongs to

You may easily put these commands in a small script that parses each entry from your passwd
