NAME
       nologin - politely refuse a login

SYNOPSIS
       nologin [-V] [-h]

DESCRIPTION
       nologin	displays  a message that an account is not available and exits
       non-zero.  It is intended as a replacement shell field  to  deny	 login
       access to account.

       If  the	file /etc/nologin.txt exists, nologin displays its contents to
       the user instead of the default message.

       The exit code returned by nologin is always 1.

OPTIONS
       -h, --help
	      Display help text and exit.

       -V, --version
	      Display version information and exit.

NOTES
       nologin is per-account way to disable login (usually  used  for	system
       accounts	 like  http  or	 ftp).	 nologin(8)  uses  /etc/nologin.txt as
       optional source for non-default message, the  login  access  is	always
       refused independently on the file.

       pam_nologin(8) PAM module usually prevents all non-root users from log‐
       ging into the system.  pam_nologin(8) functionality  is	controlled  by
       /var/run/nologin or /etc/nologin file.
