haskell getArgs

Question

How does getArgs work, I am trying to read in a text file from the terminal which then sends the contents to one of my defined functions. Can someone post an example code to give me an idea of how it works. Thanks.

Accepted Answer

`getArgs` is an `IO` action which produces a list of `String` ``` fmap someFunction $ readFile =<< fmap head getArgs ``` or in Applicative style: ``` someFunction <$> readFile =<< head <$> getArgs ```
