Can I start a program and log back in later to interact with it? This with SSH on command line, no desktop. I always seem to get a new session. I know the program is still running but I can't talk to it.
I believe the program you are looking for is "screen".
Note: I know many people these days recommend "tmux" over "screen". I am a long time user of "screen" and a recent uptaker of "tmux". I have to say that while "tmux" has some really nifty new features, it is far from "done". I've noticed a lot of weird quirks and cannot recommend it to the new user. "screen", OTOH, has been around a very long time, and is a really mature, stable product.
Therefore, I recommend "screen", unless you have a really good reason for wanting "tmux" and are willing to deal with its eccentricities.
Anyway, back to topic, OP should install screen
and start playing around with it.
