The Linux and Unix operating systems use the UID -- user ID -- to identify a particular user. The GID, or group ID, is used to identify a group. Each user will have a single, unique UID and a primary GID. The user can belong to several secondary groups and each secondary group will have a unique GID. The "id" command can be used to show the UID and GIDs for a particular user. The root (super) user can view the UID and GID for any user. If you do not have root privileges, you can only view your own UID and GID.
