What is group ID and ID? Normal user IDs are assigned to individuals who use the system interactively. Each user has a unique user ID used to identify the user on the system. Each user can also be assigned one or more group IDs, Group IDs are shared by users in the same group and are not necessarily unique.
What is used to specify a group ID? -g, –gid GID : This option is used to provide a group id (numeric) to the new group, and it should be non-negative and unique unless explicitly created to be non-unique (using -o option). If this option is not used, the default id is assigned, which is greater than every other group already present.
How do you set a group ID? First, assign a new UID to user using the usermod command. Second, assign a new GID to group using the groupmod command. Finally, use the chown and chgrp commands to change old UID and GID respectively. You can automate this with the help of find command.
