I just discovered Turtle yesterday, a library for Haskell. Obviously I haven't used it much in that time, but superficially it looks amazing. See http://hackage.haskell.org/package/turtle-1.0.0/docs/Turtle-Tutorial.html http://hackage.haskell.org/package/turtle-1.0.0/docs/Turtle-... and http://www.haskellforall.com/2015/01/use-haskell-for-shell-scripting.html http://www.haskellforall.com/2015/01/use-haskell-for-shell-s... Here's an example: #!/usr/bin/env runhaskell {-# LANGUAGE OverloadedStrings #-} import Turtle main = do cd "/tmp" mkdir "test" output "test/foo" "Hello, world!" -- Write "Hello, world!" to "test/foo" stdout (input "test/foo") -- Stream "test/foo" to stdout rm "test/foo" rmdir "test" sleep 1 die "Urk!" Haskell is strongly typed: the first argument of `output` is a `FilePath`; the second is a `Text`. In some respects, strongly typed is the opposite of power tho, because there's all these things you can do, like accidentally (or deliberately) pass a Text to a function expected a FilePath without translating it first.
