+; 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.
