I'm working on an AIX and cannot install screen but want to use its capabilities. Basically I want to be able to run a session (maybe logout), then the same user but logged in again to be able to get it back to the foreground.

I send a job to the background and login with the same user on the machine and jobs does not show it so I can get it back in fg.

You do not want to install screen then don't, your choices are dtach, tmux and byobu. No magical fairy will let you do what these programs do without installing something.

Other options would be to use the console and some kind of terminal concentrator. Or start up an xvfb and run a terminal inside of it, attaching via vnc. But screen is your best bet, I think.

Login from a workstation which will remain online, and then use the portmir command to attach to that running process. You won't have scrollback, but you can take over the terminal.

You could log the terminal with the "script" command to a file if you need scrollback. Of course, if you nohup that's what nohup.out is for. – Demosthenex Feb 29 '12 at 17:57
