What is "motd"

MOTD may refer to either one of these things:

• Match of the Day, the BBC's main football television programme
• motd (Unix), "Message of the Day" (or "Motto of the Day"), a regularly updated message often forming part of a computer program
• More on the door, abbreviation used on concert listings where advance tickets are sold cheaper
• " Mothers of the Disappeared", a song on U2's 1987 album The Joshua Tree

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.
