thanks, it worked, but could you explain how qx does it?

    The 'qx' keyword is just another way to write the back quote (`). The code -
    $n = qx/ $got /;

    [download]
    is equivalent to
    $n = `$got`;

    [download]
    What it does is to execute the $got command, and capture its output to a scalar.

    You should have a look on CPAN perlop under the section "Quote and Quote-like Operators".

    Update: Thanks to ysth to point out my typo.
