This time it is not a question but a solution to a problem which was 
quite boring.

Using the TProcess component to launch antother task, I ran in trouble 
when dealing with piped commands like 'ps -s | grep something'
Got the solution:

   with TProcess.Create(nil) do try
     CommandLine := CmdLine.Text;
     Options := Options + [poWaitOnExit, poUsePipes, poStderrToOutPut];
     Execute;
     Memo1.Lines.LoadFromStream(Output);
   Finally
     Free
   End

CmdLine.Text := '/bin/sh -c ''ps -s | grep something'' '
THis works fine whatever the sh could be (I use bash)

Antonio.
