I found these two methods googling:

Method 1:
- start the process from console
- send it to background CTRL + Z
- then disown -a

Method 2:
nohup command

I have the situation…
I did ssh to the remote server. Run the yum -y update command without nohup!
The updating run for a while and I want to log out off the remote server…and I want yum still run even I log out..
How can I use ‘nohup’ without canceling my update !
thanks for any suggestions !!

Hi and thanks for the reply. I am seeing error messages that files cannot be found that I know are present in a different folder (where it should be looking). That is what concerned me that I might have forced the process to look only in it’s current directory with “./”. When I get the prompt back I can ps and see the job running.

What kind of error you get in log files? When you get prompt back what do you see with ps and jobs command?

I just checked with my Unix admin who thinks that it does not matter whether you include the ./ in the nohup string. Also, If I hit return during the process I get my prompt back and can run a monitoring script.

Thanks for the reply. Yes command is in current directory but nohup log lists several complaints about not being able to find various files. Also, when executing, I was expecting to be returned to the command prompt which I was not.

./ means run command from current directory. Do you have command in current dir?

I used nohup as follows… nohup ./command &. Did I make a mistake in putting the “./” in front of the command when executing it?

Screen is definitely the best way to do this.

You can run commands and then detach the screen, Ctrl+a+d and leave the command running

Thank you. I’ve been searching for this. I knew this kind a functionality should exist. Often i had this issue when ever I’m connecting from home to my office-server.

Brock, seems good choice, thanks

Screen is good, but there’s also “disown” in bash, which leaves jobs running even if you log out.

Heh, my bad.

Stoyan thanks for reminding us about screen manager :) I will update post tomorrow (it is late night now) with screen utility.

I have screen installed on all servers. Not only detaching (nohup), but also opening new consoles etc.

You forget the other easy way to do the same: the ‘at’ command!

> echo “pullftp.sh” | at now + 1 minute

Then logout. After the job completes, you’ll even get an email message with the contents of stdout/stderr.
