Shell Scripting in Haskell (from http://www.yesodweb.com/blog/2012/03/shelly-for-shell-scripts)

gistfile1.hs

import Shelly
import Prelude hiding (FilePath)

sudo_ com args = run_ "sudo" (com:args)

main = shelly $ verbosely $ do
apt_get "update" []
apt_get "install" ["haskell-platform"]
where
apt_get mode more = sudo_ "apt-get" (["-y", "-q", mode] ++ more)

Uncanny: Bash's extension is "sh" and Haskell's is "hs"
