Hello Monks,

I've figured out what most of this does. I'm wondering what the last line is doing and where I can read more about it. Its a snippit from a perl script used to run a command in windows. 
my $result = qx($CommandGoesHere);
$rc = $?;
$rc = $rc >> 8 unless ($rc == -1);

[download]
in particular the $rc >> 8 And why it is the number 8.

I tried searching here and google but havent had much success due to it being code. Any links to where I can do some further reading would be greatly appreciated.

Thank you,

Jason
