(This is a HP-UX category and that script is meant to work on a UNIX branded OS.  If you want Linux answers post in a Linux category.  If you want, we can ask this topic to be moved.)

That was a debugging line that I should have left commented.  I've updated that post.

 

>what I need to change if run it at Linux server?

 

Lower that 90 and see if you pick up some PIDs?

Look at your Red Hat manpages for 'ps'; look at the thread Dennis suggested as a "starter"; and TRY to construct your own solution.  Then, if/when you are stuck ask for help.  You cannot expect every Unix variant (e.g. HP-UX, AIX, Solaris, Mac OS X) to have exactly the same semantics and syntax.  The GNU toolsets which comprise the various Linux distributions are generally far richer in features.  Learn to fish and you will never go hungry.
