I started a process yesterday that I believe will take a few more days to complete. I'm logged into my Gnome desktop, and have ssh'd into another host where I'm running the job. I'm a little nervous now that my SSH connection may drop/system will crash/other catastrophes could happen, so I would like to know if its possible to use something like `nohup` now that the job has already started, so that if anything happens to my connection, the job will continue until complete. It's currently running in the background at this point, but now that it's started can I modify it?
I know this isn't what you asked, but for all those processes I try to make sure I start them in a screen (http://www.gnu.org/software/screen/screen.html) session. It lets you detach from where you are at and reattach at a later time. You can also attach from another terminal without detaching from your main terminal to see what's going on. It can be a real life saver for the drop outs, as well as a long install. This way I can detach, go home, and re attach and still have a long running process going, and not have to sit at my desk until its done.
Peace.
john
