executing script even when we close connection via ssh

sanaz · 02-18-2013, 10:14 AM

Hi all,

I need to run a shell script on e remote machine, my connection is now strong, or I want to shut down my machine. But problem is when I close my connection(or lost it), execution of script is terminated. I googled a lot, I saw using of nohup or screen, but none of them worked for me. I really need to do that.

Any help is appreciated a lot.

What did you try?

nohup:

Code:

nohup ./script > script.out 2>&1 &

screen:

Code:

$ screen -S thisismyscreen bash
$ ./script

Then you can use Ctrl+a d to detach from the screen, and "screen -r thisismyscreen" to reattach.

Thanks a lot for your answer, but is this after I ssh to remote machine?
Could you please explain it more?

and here it is what I am doing

which does not work at all)

Code:

ssh root@remoteserver screen -d -m ./script

Better use nohup instead of screen cmd. (See manual here)

Code:

~$ nohup ./script.sh > /path/to/output

Both of my examples are intended to be run after you log in and are sitting at an interactive command prompt on the remote server. Once you run them, you can then log out of SSH and close the terminal without the background process aborting.
