Hi,

you may want to take a look at tr// (`translate'), especially the `s' modifier. This will replace multiple duplicated characters with one instance of the required character.

For example, in your line

$_=~s/ +/\t/s;,

(the $_ isn't really necessary here) you could have

tr/ /\t/s;. I understand it's quite a bit more efficient.
