Sorry for such lame question but ..
When i am connected to server using SSH . How can i fetch process to background and close ssh session and not kill that process? And how can i later connect to server and fetch process from background to console?
All years i have been using "screen" for this.
Thanks in advance!

IIUC your question, the bash job control facility should allow what you need. "Man bas:, see JOB CONTROL.
Thanks in advance!

Why not continue with screen on CentOS?
yum install screen

Screen is certainly the best method to do this that I have found ... is there a reason why you DON'T want to use screen.
you can use the '&' to put things in the background and use the command 'fg' to bring it to the foreground ... but screen also redirects stdout and stderr for you, so I would still use it unless there is a specific problem you are trying to address.

Or if you want a more modern approach - use freenx on the server and the NX client from www.nomachine.com. This will give you a complete GUI desktop that you can suspend when you disconnect and you can simply leave each process running it its own window so it is easy to find.
And - you can run the whole session over an ssh connection mananged by the client and it is very efficient even when run remotely.

Ctrl-Z will suspend the process, then run the "bg" command to continue running it on background, then run "disown %1" to make your shell "forget" about the job and not send it a HUP (Hang-Up) signal when you log out from it.
I works, unless your process will try to read from stdin, in that case it might be killed because there is no controlling tty (or something to that effect).
In general, though, running it on a "screen" session is a much better alternative, because you then can detach (Ctrl-A, d) and reattach (screen -xRR) to continue watching the output. The only problem is that you must remember to use "screen" *before* you start running your process...
