in reply to checking for piped input data

In script.pl -y goodbye | script.pl -x, the effect of the "|" in the shell command is to provide the STDOUT of the first script as the STDIN of the second script, just as if you'd written:

script.pl -y goodbye >tempfile
script.pl -x <tempfile

So for this case you don't need to know anything about pipes and IPC, just read from STDIN.

    Thank you hv! This is super helpful and resolved my confusion. I was able to write a small test script to do what I need.
