SYNOPSIS

       nologin

DESCRIPTION

       The nologin command displays a message that an account is not available and exits non-zero. It is intended as a replacement shell field for
       accounts that have been disabled.

       To disable all logins, investigate nologin(5).

SEE ALSO

NAME

     nologin -- file disallowing and containing reason for disallowing logins

DESCRIPTION

     The file /etc/nologin, if it exists, causes the login procedure, used by programs such as login(1), to terminate.	The program may display
     the contents of /etc/nologin to the user before exiting.

     This file is a simple mechanism to temporarily prevent incoming logins.  As such, the file /etc/nologin is created by shutdown(8) five min-
     utes before system shutdown, or immediately if shutdown is in less than five minutes.  The file /etc/nologin is removed just before
     shutdown(8) exits.

     To disable logins on a per-account basis, see nologin(8).

     The file /etc/nologin has no affect on the login procedure for the root user.

FILES

     /etc/nologin  The nologin file resides in /etc.
