Hi Rob.
I'm trying to help. Really I am. But first of all it looks
like you should be writing a bash script file (Perl isn't
a scripting language).
Please explain:

This will grab the output of the command line into a
Perl array '@ip' of output records.
You seem to be doing this so that you can get the PID '6762'
from the output?

OK, now you're getting the output records of another command
into another array '@script' which you never use again.
You seem to be doing this so that you can get the PID '6762'
from the output in a different way?

You're printing the contents of Perl array @nab (which you
haven't used before) saying that each element has been
'killed'. The array is empty and this will output nothing.

And now you're printing the contents of '@ip' with each
record prefixed with '/opt/script.pl ' and an additional
newline appended.

This part I don't understand at all. Perhaps others do?
What is 'ks.pl'? Is it the name of the Perl script that
you've shown us?

You're writing a Perl program which essentially runs 'ps'
and prints the output slightly reformatted.
Try to explain what it is you want to do.
And I still think you should be writing a bash script!
I hope this helps in some way.
