Try it. It is "technically" the same as:
if ($2 eq '-') { $2 }
Used in the context of:
>s/(.{1,100})( |-)/$1 . ($2 eq '-' && $2) . "\n"/eg;
Here is an example:
$x = "foo";
$y = $x e
What exactly does this ($2 eq '-' && $2) do? Must it be in parenthesis?

Hello
I was wondering if someone could point me in the right
direction for the following regex.
s/(.{1,100}(?: |(\-))/$1$2\n/g;
Please help on the second (?: |\-)
I am trying to match either a single space ' '
or a - after 100 other characters and I want to save
the - but not the ' '
thereby $2
