USERINFO(8) System Manager's Manual USERINFO(8) NAME userinfo - displays user information SYNOPSIS userinfo [-e] user 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. SEE ALSO passwd(5), group(8), user(8), useradd(8), userdel(8) HISTORY The userinfo utility first appeared in NetBSD 1.5. It is based on the addnerd package by the same author. AUTHORS The userinfo utility was written by Alistair G. Crooks <agc@NetBSD.org>. NetBSD 8.0 November 16, 2005 NetBSD 8.0
