How do I detach a process from Terminal, entirely?
I've a program running in a Unix console on a remote Unix computer. I (stupidly) didn't run it using nohup &, and now I need to close the local console.
Is there any way to have it keep running remotely after closing the local console?

If your shell is bash, they you can use disown. Ctrl-Z to suspend the process, then disown -h to make it not receive SIGHUP.

On Solaris 9, you can use nohup -p <pid> to nohup a running process. Here's an interesting explanation of the implementation. I don't know if this has been implemented on any other Unices.

nohup: invalid option -- p Doesn't work on gentoo, ubuntu or fedora (the unixes I tried this on), but thanks nevertheless :-) Good to know Solaris has it. – Thrawn – 2010-03-26T18:37:11.393

Ctrl-Z to suspend the process, then bg to cause the program to go into the background and keep running until it completes.

Problem is that if I close the console, also the background processes will stop. I need something that detaches the process from the console, like nohup does, but after the process has started :-) – Thrawn – 2010-03-26T12:58:56.337
And I don't think 'nohup bg &' will work either :-( – Thrawn – 2010-03-26T13:19:20.780
1I tried it on one of my systems and it kept running fine when I logged out (just used du / >> temp as the test progrm) but I understand being hesitant if you don't want to lose the program or it's results. – Matrix Mole – 2010-03-26T23:17:38.720

If you can afford to stop the program and restart it before logging out, then stop it and restart it through screen, which is a must for anybody using remote connections to unix hosts.

1I think the main problem here is precisely that he would like to not stop the program. – Gnoupi – 2010-03-26T15:34:06.873
1Yeah, I would like the program not to be stopped :-) – Thrawn – 2010-03-26T18:32:42.123
I would highly suggest screen for future use of such a situation (I pretty much always have a screen session running on any system i have a sehll o). – Matrix Mole – 2010-03-26T23:16:09.910
1Several years later, I realized I was a fool not to be using screen :-) – Thrawn – 2012-08-27T12:48:57.897
Brilliant solution. It worked :-) – Thrawn – 2010-03-29T09:22:33.927
3Just curious: as the process is suspended, shouldn't this eventually be followed with
bgor something like that? Or doesdisown -hresume it as well? – Arjan – 2010-04-25T15:13:19.783Will this work if the process is running inside
screen? I would like to continue running the process in my regularxterminstead. – voices – 2016-03-19T04:22:16.280IIRC once disowned it won't be connected to any terminal – Douglas Leeder – 2016-03-20T16:31:07.343
