Message Of the Day File
===================
The /etc/motd is a file on Unix-like systems that contains a “message of the day”, used to send a common message to all users, in a more efficient manner than sending them all an e-mail message.
The contents of the file /etc/motd are displayed by the Unix login command after a successful login, and just before it executes the login shell
