By using duff's solution with the Matching the word boundary \b so that you don't chop off the text in the middle of a word.

update:
A clumsy other way to do this :)
use strict; use warnings; my $txt = "just wondering how i can have perl display part of my long +memo. basically i want the first lets say 255 charachters of the para +graph. im really new to perl so i don't know how i would come about t +his? a regex perhaps? just started reading about that today. so basic +ally something like"; my @a = split("",$txt); my $l = 7; for (my $i=0; $i < $l; $i++) { print $a[$i]; $l++ if ($i ==($l-1) && ($a[$i] ne " " )) ; }
