USERINFO(8)			   BSD System Manager's Manual			      USERINFO(8)

     userinfo -- displays user information

     userinfo [-e] user

     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.

     The userinfo utility exits 0 on success, and >0 if an error occurs.

     passwd(5), group(8), user(8), useradd(8), userdel(8)

     The userinfo utility first appeared in NetBSD 1.5.  It is based on the addnerd package by
     the same author.

     The userinfo utility was written by Alistair G. Crooks <agc@NetBSD.org>.
