MOTD

The image above is a "Message Of The Day" or MOTD. It's presented as a sort of 'splash screen' when logging into a remote system via SSH. This article is about how to create your own custom MOTD.

The Ubuntu distribution introduced the update-motd framework which basically assembles the motd from the series of scripts in /etc/update-motd.d

You should read the motd manpage (which you can also access in your console via man update-motd Sadly, the motd man page doesn't even refer to update-motd which is where the details are!?)

Essentially, you create a file in /etc/update-motd.d with a numbered prefix and no suffix. The first line of output should be blank, and the last line of the script should be a carriage return.

cat /etc/update-motd.d/99-footer
