in reply to Merging two pipes

Your pseudo-code and your words tell me two different stories. First your pseudo-code (and without the die's):

open INPUT from some_script; read input if some_condition open >&INPUT from some_other_script do_something

While you say that you want INPUT from one script, and output from two scripts to one pipe. That means:

open INPUT, "some_script |"; open OUTPUT, "| some_other_other_script "; while (<INPUT>){ if ($some_condition){ open INPUT2, "some_other_script |"; print OUTPUT $_ while <INPUT2>; } print OUTPUT $_; }

Whatever the case, think of the two forms of pipe (input/output) and realize that ">&INPUT" is just an illegal name for a GLOB.
