User identifier (Unix)
On Unix-like systems, users are represented by a user identifier, often abbreviated UID. The range of values for a UID varies amongst different systems; at the very least, a UID can be between 0 and 32767, with some restrictions:
  • The Superuser must always have a UID of zero (0).
  • The user "nobody" was traditionally assigned the largest possible UID (as the opposite of the Superuser), 32767. More recently, the user is assigned a UID in the system range (1–100, see below) or between 65530–65535.
  • UIDs from 1 to 100 are otherwise reserved for system use by convention; some manuals recommend that UIDs from 101 to 499 or even 511 be reserved as well.
The UID value references users in the /etc/passwd file. Shadow password files and Network Information Service also refer to numeric UIDs. The user identifier is a necessary component of Unix file systems and processes. Some operating systems might have support for 16-bit UIDs, making 65536 unique IDs possible, though a modern system with 32-bit UIDs will potentially make 4,294,967,296 (2 raised to the 32nd power) distinct values available.
