Is there any command which can list me all the Group ID's (Primary, Secondary ) assocaited with a single user.

Thanks
Sanjay

Have you try the id command ?

id [-gnruG] [--group] [--name] [--real] [--user] [--groups] [--help] [--version] [username]

By default, it prints the real user ID, real group ID, effective user ID if different from the real user ID, effective group ID if dif ferent from the real group ID, and supplemental group IDs. It prints each of these values preceded by a string identifying it and followed by the corresponding user or group name in parentheses. Post back if this doesnt help..

Thanks !
I always looked in the default id command and I did not look in the options.
This will work for me.
