I'm trying to write an anagram finder that searches through /usr/dict/words. I know there were some other posts on this, but I tried to write my own. Basically, I wanted it to do this:
% anagram_finder.pl elloh hello %
I have some code that does it using a for loop, but I wanted to get it to work using "grep". I thought it would be cleaner and nicer. This doesn't work, though I have been trying very hard to find my mistake but I have been unlucky so far:
open DICT, "</usr/dict/words" or die "no more words: $!"; $a = join "", sort split "", lc shift; print join "\n", grep {$a eq join "", sort split "", lc} <DICT>;
Any help would be greatly appreciated.
