userinfo —
displays user
information
SYNOPSIS
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.
