You must remove the user before you remove the group.You should manually check all file systems to ensure that no files remain owned by this group.CONFIGURATIONThe following configuration variables in /etc/login.defs change the behavior of this tool:MAX_MEMBERS_PER_GROUP (number)Maximum members per group entry. When the maximum is reached, a new group entry (line) is started in /etc/group (with the samename, same password, and same GID).The default value is 0, meaning that there are no limits in the number of members in a group.This feature (split group) permits to limit the length of lines in the group file. This is useful to make sure that lines for NISgroups are not larger than 1024 characters.If you need to enforce such limit, you can use 25.Note: split groups may not be supported by all tools (even in the Shadow toolsuite). You should not use this variable unless youreally need it.FILES/etc/groupGroup account information./etc/gshadowSecure group account information.EXIT VALUESThe groupdel command exits with the following values:0success2invalid command syntax6specified group doesn't exist8can't remove user's primary group10can't update group file
