Hi all, Can someone pls help me on how to make this bash script? I want to monitor a process, and then when the process (for some reason) dies, the script will start the process again. Thank you,

This is not the appropriate place for that kind of question. You should look for help on a bash mailing-list, website or IRC channel.
What you want to do sounds amazingly similar to what the mysqld_safe script does, so you might consider looking at ohter examples like that to do what you want.

One possible approach is to look at an offering from qmail's author, D. J. Bernstein http://cr.yp.to/djb.html. DBJ publishes a very useful set of tools known as daemontools http://cr.yp.to/daemontools.html. Supervise http://cr.yp.to/daemontools/supervise.html switches to the directory named s and starts ./run. It restarts ./run if ./run exits. It pauses for a second after starting ./run, so that it does not loop too quickly if ./run exits immediately.
Monit http://www.tildeslash.com/monit/ is a utility for managing and monitoring, processes, files, directories and devices on a UNIX system. Monit conducts automatic maintenance and repair and can execute meaningful causal actions in error situations.
restartWrapper (comes with Radiator) is something that has never failed our operation in a decade, but I'm not sure what the license looks like.

If you want it to happen at the system level, look at a 'respawn' entry in /etc/inittab. In a shell script, you can use ':' to mean forever in a while target:
while : do yourprogram done
You don't need create a script for this. Use one that already exists. Monit can solve your problems. http://www.tildeslash.com/monit/ There is also a rpm package for rhel4/centos4 into Dag's repository at http://dag.wieers.com/packages/monit/
