How to find all programms installed on Ubuntu 18.04

Question

I know this an FAQ, but this is a little different. My primary disk fails to boot, so I have reinstalled Ubuntu 18.04 LTS on a new disk.

The old disk is still readable, so can I find a list of all ot the programs that were installed on it, so I can install them on the new disk?

Welcome to AskUbuntu! This answer in the called duplicate should work. Just change the path to include the mount point of the old disk. — Elder Geek, Dec 18 '19 at 21:41
I don't quite see how this question is substantially different from the dupe. — user535733, Dec 18 '19 at 21:59

I'm not sure if it will give you exactly what you want but you can try it and see:

apt list --installed > file_of_installed_prog

'apt list --installed' gives me a list of the programs installed on my 'new' machine. However the suggestion in the 'Welcome' message regarding /var/log/apt/history.log may help. Probably a lot of faff, but I should get there. NOTE TO SELF - run 'apt list --installed' on a regular basis and keep the resulting list. This isn't the first time this has happened to me! – Tony Dec 19 '19 at 18:55
