Linux Idea userid

Both Linux and Unix have the idea of a userid. This is a short name, associated with files and processes, that identifies the user who owns them. The userid is stored in a file named /etc/passwd, which has more information about the user, such as their full name and office location.

Within VistA, this idea is expressed as the value of the local variable DUZ. The DUZ is a numeric value used to index the VA FileMan NEW PERSON File. This file keeps track of many details about a person, including their full name and office location.
