Hurrah!! I would like to answer my question since i have got the solution.

For example, I'm running a script newscript.sh I want to run this in background and continue someother job in the terminal or i can close the terminal.

[yourname @ username ~]$ sh newscript.sh &

and hit enter. You will get a PID and your job will be attached to the background.

To kill the same process, use the PID

For eg., kill 1205212

Thank you.

Actually, no. First of, you don't need sh:

$ ./newscript.sh &

This is enough. This will start a background process. But your terminal is still controlling it. To achieve the behavior you want, do this:

$ disown %1

This will disown the job with the jobspec 1 (which is like an id), which was the one you started beforehand. Now you can close the terminal.
