What is it doing?

Anonymous Monk has asked for the wisdom of the Perl Monks concerning the following question:

Hi Monks,
I am reviewing a script and I found a line of code which I could not understand. Can anyone explain the following line of code?.

$errn = $out >> 8;
[download]

thanks.

See Shift Operators.	[reply]

Errrm, shifting `$out` right by 8 bits - probably removing any signal number from the result of a call to `system()`...see system...or, more pertinently Shift Operators Update What use is a link to the call, the OP asked about the op, so added link to that as well. A user level that continues to overstate my experience :-))	[reply] [d/l] [select]
