When you login to either a tty or a remote machine by ssh there's normally a banner which looks like this:
Welcome to Ubuntu 12.04 LTS (GNU/Linux 3.2.0-25-generic x86_64) * Documentation: https://help.ubuntu.com/ 0 packages can be updated. 0 updates are security updates.
where is the script/group of scripts that produce this message located? I'd like to customise it.
I assume that it's part of the login process and not bash since you don't see it every time a terminal is opened.
