[Linux] Bash groupdel Usage: Remove a user group

Overview

The groupdel command is used in Linux to delete a specified user group from the system. This command is typically executed by a superuser or an administrator, as it modifies system group information.

groupdel [options] GROUP_NAME

Where GROUP_NAME is the name of the group you wish to delete.

• -h, --help: Displays help information about the command and its options.
• -V, --version: Shows the version information of the groupdel command.

Common Examples

3. Display help information:

Tips

• Always ensure that the group you are deleting is not currently being used by any users or processes to avoid potential issues.
• Use the getent group command to verify if the group exists before attempting to delete it.
• Consider backing up your system’s group file (/etc/group) before making changes, especially on production systems.
