Since nobody has said yet, I use screen pretty heavily. Want to run a long running task, starting it from your phone? Run screen to create a detachable session then the long running command. You can then safely close out of your terminal or detach with ctrl a, d and continue in your terminal doing something else. screen -r to get back to it.
How does screen / tmux work when detached from a session, how does it keep the session alive (both when running locally, and while ssh:ing to a server)? Is there a daemon involved?
You can find out by running screen and executing pstree, that way you can see how the screen process is run.
