group_file_consistency

This built-in function ensures that each line in /etc/group has a valid format (e.g., three items separated by colon and a list of users). If a line is malformed, it is reported and the check fails.

Having a malformed /etc/group file may break several user-management tools. It may also indicate a break-in or a bug in a custom user-management application. It may also show that someone attempted to add a user with an invalid group name.

Edit the /etc/group file to fix the badly formed lines.

Usage
