How do I resume a suspended process in a *different* shell?

Often I have the problem of starting a large emerge and get halfway through and want to log out of X, or I have run the emerge in the console and I want to see the status in X. But I can't because I didn't think ahead and start the thing in a screen session. Is there a way that I can suspend (Ctrl-Z) and then resume (fg %1) from a screen session? I have wanted to know how to do something like this for a long time, so if someone know's fill me in on the secret!

not that I know, but you can still stop it with 'CTRL+C' then when you're ready again, run 'emerge --resume'

just be aware, that you should avoid stopping emerge process when it's copying/deleting files to the filsystem

fRIOUX: But just to be sure not to break anything, you should do the same I did in the past: I changed by personal habits.

Nowadays ALWAYS when I touch emerge -- even if just emerge --sync, I start it in screen session. Just in case.

1) Create a script that starts a screen session, then runs the emerge within it, then alias that script to emerge....

2) set your shell to the screen executable...

3) set your bash.rc to start screen last....

Any of those sound reasonable?

Yeah, that's what I generally do really. I have been using one computer all summer and when a term opens it automatically runs 'screen -x main' on start, but I was just working on a different computer and I hadn't started in a screen session. Thanks for the help anyway. I was just really wondering if there was a UNIXy, configless way to fix this issue if I didn't do things right in the beginning.

I wonder if retty could help you in those cases.

I always just use screen. It's easier, and if it's a big emerge, I can ssh in and monitor it from work, capture a log file, etc. It's your best option.

Screen will spoil ya.

I've started a job outside screen, but have found out that it's going to take a while to finish
and want to move inside a screen shell.

Does anyone know how I can achieve that?

Do you have to have to move it to screen?

If you just didn't want to leave the xterm open, you could probably suspend the emerge process, background it and then disown it.

How do I resume a suspended process in a different shell?
