User groups in Linux

While performing particular task in Linux based distro one might need to verify if that user belongs to a group with right permissions.

You can verify this using two simple commands.Open your terminal and run groups,

udara@thinkPad:~$ groups
udara adm cdrom sudo dip plugdev lpadmin sambashare

This will show the groups which logged-in user belong to.

If you wish to find the groups of any other user just run, groups {user_name},

udara@thinkPad:~$ groups udara
udara : udara adm cdrom sudo dip plugdev lpadmin sambashare

udara@thinkPad:~$ groups root
root : root
