What is the primary function of the groupmod command in a Linux environment?
To create a new user account on the system
To modify file permissions for a group of files
To add or remove a user from a group
To modify a group's name or GID (Group ID)
The groupmod command is used to modify a group's details, such as its name or Group ID (GID). Knowledge of this command is crucial for system administrators when they need to manage group information and its related security implications. For example, changing a group's name might be necessary when organizational roles change or to correct errors in naming conventions. The incorrect options provided are related to user and file management, not directly to groups, which may lead to confusion, but understanding groupmod pertains specifically to group modifications.
