Sadly, this monad can't stop you from doing dangerous stuff in the first place, like iterating over the output of ls:

Interesting, why not try to build this based on Shelly? (http://hackage.haskell.org/package/shelly)

I wrote this with shelly open in another window; it's intentionally got some similarities. It might be possible to extend shelly's Sh monad so it can generate shell code, rather than its current behavior of running IO actions, but that seems like a stretch to me.

Performance varies on each scripting language I think. I personally have my own preference in scripting.
