NAME
 userinfo — displays user information
DESCRIPTION
 The 
userinfo utility retrieves the user information from the system. The 
userinfo utility is only available if built with 
EXTENSIONS. See 
user(8) for more information.
The following command line option is recognised:
- 
-e
- 
Return 0 if the user exists, and non-zero if the user does not exist, on the system. No information is displayed. This form of the command is useful for scripts which need to check whether a particular user name or uid is already in use on the system.
The user argument may either be a user's name, or a uid.
 
EXIT STATUS
 The userinfo utility exits 0 on success, and >0 if an error occurs.
HISTORY
 The userinfo utility first appeared in NetBSD 1.5. It is based on the addnerd package by the same author.
