Looking at some troubleshooting logs, I saw really cool logs of terminal sessions. When they were short, I figured that they’d been recreated (i.e. typed in again), but with longer logs, I guessed there had to be a logger. That got me started. Yes, indeed there is! And it’s one of the most basic things in linux, esp as a new user!
Just type "script <filename>" into a terminal you’re on and the recording starts to your <filename>. If you leave out filename, it’ll create a file called typescript and log all the output from the terminal screen there.
