i need a script to check my startup for start restart stop linux centos
 

I have startup scripts
I want to test them
I need a script to do the following
start restart stop for 100 times (or i can set how many cycle)

hmmmm ... let me see if I think you have thought about this .... start restart and stop all startup scripts 100 times ... so when we stop maybe the X server
(even once) where do we see ourselves?? maybe we could try it on the mountall script (or equivalent) so now we remove the root mounting whilst perhaps performing other tasks ??? can't see any problems .... can you?

I think you should take this one back to the drawing board as to what you are actually trying to achieve here?
