  • this is what screen(1) was invented for. First thing you do when you log in to the remote box, run screen, then run all your other stuff within screen. They'll keep going even when your connection dies, and you'll be able to re-connect to them.
    • I have lived such the life of privilege up to now that these things are foreign to me.

      Still, how often do you get to sit at a computer, a public one no less, with a loaded pistol? I did unholster it and threaten the computer, and everyone laughed. I was really going to put a bullet through the screen though. I mean, I have enough money to replace it, and I have not shot a computer since Camp Camel.
      • Even though I'm in the Land Of Copious Bandwidth And Sane Client Machines, I still use screen. It means I can leave my IRC client connected all the time and just ssh in to see what rude things people have been saying about me.

        There are six key-strokes you need at minimum to drive screen. For all of them press C-a, then ...

        a - type a literal C-a (so that's C-a, a)

        c - create a new screen

        d - disconnect

        n - go to the next screen

        p - go to the previous screen

        ? - help! help! i'm being repressed!

        • Hey, thanks for the info. My usual development cycle has been---download, go away, read docs, plan my half hour of time, try something, fail, repeat.

          Shortcuts and wisdom cut down on that. :)
          • I'm too used to using control A to mean start of line to cope with screen usurping it, so I make screen use control O. I also like more scrollback lines than the default, so I tend to invoke screen as screen -e^Oo -h 5000

            I'm not a big vi user, so the lack of control O doesn't bother me.

            (Actually, I've got nested screens on different machines, sometimes 3 deep, with O, J and _ as the command keys. I thinK I identified control ^ as a viable 4th level screen)
