Pointer re choroba's answer: perlre, perlretut, etc. As you've written the regex, it's effectively a noop because you haven't assigned a value to $dir.

Beyond that, it may be that your intent and the regex's behavior don't agree. The \n is the wrong way to tackle the end of a line -- if, in fact, you need to anchor to an EOL... but you haven't offered any information to suggest it's needed at all.

So, perhaps you want something like this (after assigning a value to $dir):

$dir =~ m/([a-z:]+).*?/; $dir = $1; print $dir;

The parens capture to $1 the content matching a-z & colon more than one time... for ex, "C:"
