userinfo
—
displays user information
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.
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⟩.
