NAME
     userinfo — displays user information

     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.
