How to attach to a nohup process?

Question

If I start a process with nohup:

nohup WHATEVER &

then how can I see it again? I mean how to attach my terminal to it again under Linux, e.g.: Ubuntu 11.04 - just like with the screen package.

Answer 1

What do you want to do with it?

As other poster has said, screen is better, you can attach/reattach.

nohup does not disconnect from terminal, it makes your app ignore SIGHUP, and (usually) redirects stdout/stderr. Run jobs in your terminal. It may just be a background job, and you can bring it back with fg. I don't know how to get stderr/stdout once you redirect it.

Answer 2

You should have used screen in the first place as it is a lot more flexible than nohup.

But if you want to attach to the process in the same way as screen, this link provides more info : http://serverfault.com/questions/24425/can-i-nohup-screen-an-already-started-process

Basically you can either use reptyr as described in the link, or you can use an old script called screenify. I found the script here : http://isteve.bofh.cz/~isteve/knowledgebase/articles/screenify.html
