The user’ quotas on the server were reduced from 200MB to 100MB. Besides sending emails to all
users, it was requested that a message should communicate the change every time a user access the
server. Which of the following is the correct method to configure this?

A.
Put the message text in the /etc/login-message file

B.
Put the message text in the /etc/motd file

C.
Put the message text in the /etc/default/login file.

D.
Put the message text in the /etc/passwd file, after all users entries.

E.
There is no way to do this because the administrator has no permission to change the
.bash_profile file for each user.

From the man pages
The contents of /etc/motd are displayed by login(1) after a successful login but just before it
executes the login shell.
