No. This prints the fields you want when you call system(), and returns
the error code (0) to $Last. system() is documented thus -- it executes
what you tell it to execute, and returns the return value.
If you want to capture the output, use backticks instead:
$output = `$command`;
or
$output = qx!$command!;
The qx// operator, as well as backticks (``), are documented in perlop.
