userinfo -- displays user information
userinfo [-ev] 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 options are 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.
-v Perform any actions in a verbose manner.
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), usermgmt.conf(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>.
