in reply to output of one program doesn't show in another on server

First, try adding the interpreter you need to run the program - depending on your OS, you may need to add:
at the start of your "".

The second thing is that you should check the return value after running the command in backticks. Try this:

my @ret = `\usr\bin\perl ./`; if ($?) { die "Error running \[] : $!"; }
Getting errors back to the user's web page when running under CGI is non-trivial.
Look at the CGI::Carp module, and the "fatalsToBrowser" option.

Update:Fixed a few typos.
