Perl will interpolate @list here and replace it with "", since @list is
empty.
(Which is just as well, since the shell has no idea what a perl array is.)

Get your system command to write its output to stdout and capture the output
with backticks:
$output = `$command`
Or, open the file created by your command and read it.
Also, consider using the LWP::Simple or LWP::UserAgent modules, which let
you make HTTP and other requests directly from Perl.
