I don't think the below is the correct way to run some_process as user

Code:

		echo "some_process not running.. Starting.."
        	echo "passwd" | su - user
        	nohup ./some_process &
		echo "PS : $(ps ax | grep some process)"
                echo "passwd_of_original_user" | su - original_user
		echo "PS : $(ps ax | grep some process)" #some_process is already not running at this line

Instead try something like this:

Code:

		echo "some_process not running.. Starting.."
        	echo "passwd" | su - user -c "nohup ./some_process &"
		echo "PS : $(ps ax | grep some process)" #some_process is already not running at this line

However su on many systems will also refuse to accept passwords from a pipe issuing an error like standard in must be a tty.

sudo is usually a better choice in this situation, as the requiretty constraint can be relaxed for some_process or user.
If as I suspect you have little admin control over host you may be forced to run another expect script to get some_process running as user
