in reply to FILEHANDLE not visible outside subroutine

You should always check the return value of open:
open PS, "$psout |" or die $!;

Update: Also, it seems you are running the sub in a thread. Why do you think a filehandle would be shared?

    Hello choroba ,, I'm sure the open statement returns just fine ,. Although , I was not aware filehandles could not be shared in threads (newbie :/) , thank you so much for pointing that out . I have modified the code to avoid the filehandle statement , and used a shared variable to store the command output , it works great !! .. Thanks again ... :)
