When you login, you are shown "X packages can be updated, Y are security updates," Is there a terminal command that will give this message on demand?

The login message is called "motd". It's configured in /etc/motd and /etc/update-motd.d, so you could check there to see what command prints that message. Related: How to change welcome message (motd) on Ubuntu 18.04 server - LinuxConfig.org – wjandrea May 30 '19 at 13:51
@wjandrea thanks, this is 16.04 and it's not where you suggest (neither file exists) any idea where it might be on 16.04? – user1130176 May 30 '19 at 15:58
@user1130176 Oh, you're right, /etc/motd isn't used anymore, but /etc/update-motd.d should still exist. You're aware it's a directory, right? See man update-motd. Maybe it's in /etc/pam.d/login instead? See man motd. – wjandrea May 30 '19 at 16:58
