Yes, and I can remove three additional chars by using bareword a and f rather than strings:

@ARGV="/usr/share/dict/words";while(<>){$a='a';$a++while/$a/i;push@{$_
+[length]},$_ if$a gt'f'}@_=map{$_?@$_:()}@_
@ARGV="/usr/share/dict/words";while(<>){$a=a;$a++while/$a/i;push@{$_[y
+///c]},$_ if$a gt f}@_=map$_?@$_:(),@_

And who needs a path when perl can just guess? :P. @ARGV=</*/*/*/words>;while(<>){$a=a;$a++while/$a/i;push@{$_[y///c]},$_ if$a gt f}@_=map$_?@$_:(),@_ Which brings the count to 100 chars (including the \n)

I'm not accustomed to needing to specify the argument within the code. It's not like it's a command-line flag. I count yours at 78.

while(<>){$a=a;$a++while/$a/i;push@{$_[y///c]},$_ if$a gt f}@_=map$_?@
+$_:(),@_

If you're to actually print out the shortest, make it 89. Still quite a bit shorter than mine.

while(<>){$a=a;$a++while/$a/i;push@{$_[y///c]},$_ if$a gt f}@_=map$_?@
+$_:(),@_;print$_[0]

Of course, looking closely only one of your loops needs to be of the 'while' variety. 87 (or 76 unconcerned about output).

for(<>){$a=a;$a++while/$a/i;push@{$_[y///c]},$_ if$a gt f}@_=map$_?@$_
+:(),@_;print$_[0]

for(<>){$a=a;$a++while/$a/i;push@{$_[y///c]},$_ if$a gt f}@_=map$_?@$_

Since the discussion started as a comparison against python, I wanted to play fair-ish and have code that actually does the same thing (technically, the same thing as the perl version in the OP). That's why I didn't include the glob version in the first place, or didn't print the result

Nice catch! I'm far too used to using while for files to have seen this one :-).

Two chars off if you put the constant first in the commaprison (good practice anyways :) and get rid of the 'if' statement modifier using '&&':

for(<>){$a=a;$a++while/$a/i;f lt$a&&push@{$_[y///c]},$_}@_=map$_?@$_:(
+),@_;print$_[0]

Five chars of if you get rid of transforming @_ and grab directly what you want:

for(<>){$a=a;$a++while/$a/i;f lt$a&&push@{$_[y///c]},$_}print+(map$_?@
+$_:(),@_)[0]

82. I'm sure tybalt89 can do better, though.

update: I wonder why biface isn't a verb proper, meaning treat someone with a biface. The shortest word would then be bifaced which seems fitting to me, huffman-coding anglo-saxonian history.
