nologin - politely refuse a login

nologin [*-V*] [*-h*]

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 an account.

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

The exit status returned by nologin is always 1.
