Thanks for all the replys.
My only concern now is if I open a pipe to another program if the other program automatically opens.

Senario:

I open Program 1 - Daddy -> open(SEND,"|Kiddy.pl");

Program pipes its output to Program 2 - Kiddy

Does Kiddy automatically open?


Next where does Kiddy.pl get the data from Daddy.pl
    

  1. Is it in STDIN as in -> read(STDIN, $from_Daddy, $ENV{CONTENT_LENGTH});
    

  2. Is it in -> $from_Daddy = $ENV{QUERY_STRING}; #\ This seems unlikely but you never know /#
    

  3. or do i get it like open(GET,"Daddy.pl|");
