How do I find out group membership for each user? How do I find out which users are in a group called sales?
The groups command display the groups a user is in. In this example, find out the group membership for user vivek, enter:
groups userName groups vivek
vivek : vivek adm dialout cdrom plugdev lpadmin netdev admin sambashare libvirtd
User vivek is member all of the above groups. Find out all users belongs to the group called adm:
grep -w groupName /etc/group grep -w adm /etc/group
grep -w groupName /etc/group
grep -w adm /etc/group
- /etc/group file.
