44. Managing Groups: Creating, Deleting, and Modifying

Linux Basics: From Zero to CLI Hero

Group Administration

Group commands follow a similar naming convention to user commands.

Creating a New Group (groupadd)

bash $ sudo groupadd marketing

Deleting a Group (groupdel)

bash $ sudo groupdel temp_group

Modifying a Group (groupmod)

This is primarily used to change the Group Name (-n).

bash

Rename the 'marketing' group to 'sales'

$ sudo groupmod -n sales marketing

Viewing Group Membership

  • groups: Shows the groups the current user belongs to. bash $ groups user_name sudo web_ops

  • groups username: Shows the groups for a specific user.

  • id: Shows the UID, GID, and all group memberships for a user.
