Code:
# grep username /etc/passwd | sed 's/\/bin\/bash/\/sbin\/nologin/'
username:x:32008:32011::/home/user:/sbin/nologin

NOLOGIN(5)						      BSD File Formats Manual							NOLOGIN(5)

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. EXAMPLES
NO LOGINS: System going down at 18:22 SEE ALSO
login(1), ftpd(8), nologin(8), rshd(8), shutdown(8), sshd(8) BSD
