How do I edit a group in Linux? To modify an existing group in Linux, the groupmod command is used. Using this command you can change the GID of a group, set the group password and change the name of a group. Interestingly enough, you can’t use the groupmod command to add a user to a group. Instead, the usermod command with the -G option is used.
