Shelly is a small Haskell library to support scripting tasks.

Shelly is a Haskell library to support writing scripts in Haskell that would normally be written in Bash or some other scripting language. It provides functions for basic shell commands such as pwd, cd, mv, etc. as well as environment access.

Shelly commands must be run in the ShIO monad which is sandboxed so that each instance of the monad is thread safe.
