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.
