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.

Thanks but I tried your method, It throws a permission denied exception. therefore I cannot use disown too.

what to do if we dont have a job but a process , i can run it in bg by & but when i close terminal, it also stops, how can i disown that
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.
