Making this for all the different languages would be awesome. I'm thinking PHP, jquery etc. one liners.

  Do any other languages really lend themselves to the one line command tools like perl does? The only one off the top of my head would be ruby but I don't have that much ruby knowledge to judge. This kind of thing however is perl's bread and butter.

    Benoit Hamelin did ruby one liners - http://benoithamelin.tumblr.com/ruby1line http://benoithamelin.tumblr.com/ruby1line

    Agreed - one reason why I still love Perl so much, despite its obvious warts.

    Compared to Ruby, one liners are more efficient in Perl because the normally infuriating cryptic variables and defaults save space. For example in Perl you can run a foreach without naming the current iteration value and it defaults to $_. $_ in turn is the default target for many commands, like print. So Perl's `print foreach @a` becomes Ruby's `a.each{|a| print a}`. Not so bad but it adds up.

      Ruby: print a.join Perl: print foreach @a Ruby wins!

        I think you mean: print @a;

  Here's a page for Haskell: http://www.haskell.org/haskellwiki/Blow_your_mind http://www.haskell.org/haskellwiki/Blow_your_mind It isn't exactly the same--some examples are two or three lines and it's more about coolness than practicality--but it's in a similar spirit, and, more importantly, also interesting.

    The first example: -- split at whitespace -- "hello world" -> ["hello","world"] words unfoldr (\b -> fmap (const . (second $ drop 1) . break (==' ') $ b) . listToMaybe $ b) takeWhile (not . null) . evalState (repeatM $ modify (drop 1) >> State (break (== ' '))) . (' ' :) where repeatM = sequence . repeat fix (\f l -> if null l then [] else let (s,e) = break (==' ') l in s:f (drop 1 e)) Not really in the same spirit at all.

      That blows my mind, but certainly not in a good way. Ruby: $ echo 'hello world' | ruby -e 'p STDIN.read.split'

        Be aware that those are four separate examples made to showcase features of the language, the simplest of which being just `words`. split.hs: main = interact (show . words) $ echo hello world | runhaskell split.hs

          OK, thats not really clear from the layout. Your example is clearer, but if you have to put it in a script and pipe stuff to it, its not really a 1-liner.
