Don't backquotes in Perl do the same thing as in the shell (i.e., run
the quoted command and then replace the backquoted thing in the script
with the output from the command)?  Since

  `octave --help > /tmp/octave2.out`

doesn't produce any output, it is equivalent to running

  system ('')

except with the side effect of writing the Octave help text to the
file /tmp/octave2.out.

Maybe you meant to use single or double quotes instead:

  system ('octave --help > /tmp/octave2.out');
  system ("octave --help > /tmp/octave2.out");

?
