Bash - Update terminal title by running a second command

Question

On my terminal in Ubuntu, I often run programs which keep running for a long time. And since there are a lot of these programs, I keep forgetting which terminal is for which

Answer 1

You can set up bash such that it sends a certain escape sequence to the terminal every time it starts an external program. If you use the escape sequence that terminals use to update their titles, your problem should be solved.

I have used that before, so I know it is possible. but I cannot remember it off the top of my head and do not have time to research the details right now, though.
