[Acronym] for User ID.

The numerical id that corresponds to a user.  For example 0 is usually [root].  ''bob''s UID might be 500.  UID to name mappings are stored in /etc/passwd (see passwd(5))

; Set UID ([SUID]) : A program is said to be "[SUID]" when the file has the "+s" user permission bit set, so the program will run as the permissions of the user that owned the file, not the user that ran the file.

; Actual UID : The uid listed in your auth mechanism against the username you logged in as. Alternatively, the uid a process was launched by, as opposed to the uid it runs as (the EUID)

; Effective UID (EUID) : The user that a programs permission checks are done against.  This is often root if you run a [SUID] program.  The Actual UID is your normal UID, but the effective UID is that of root.
