No these are not the LIMIT. These are array indices. You could write
the code like this:
my @items = split;
my ($country, $bytes) = @items[-2,-1];
The
my @items = split;
line splits the contents of $_ on whitespace and stores the results
in the @items array, the
my ($country, $bytes) = @items[-2,-1];
copies the last-but-one element of @items to $country and the last
one to $bytes.
You can use the
(function_call( parameters))[indices]
shortcut with any function that returns several values (eg.
localtime()), but you have to make sure you enclose the function call
in braces.
