hi

here is my problem :
  i started a process A through my ruby script using system() on my unix
os .The process A then started a process B. I want to capture the output
of the process B provided I cannot modify the source code of process A
and process B

I tried using named pipes and `` to capture the output but its not
working


thanks in advance  .
