Hi all,

Okay, so I am making a program in Haskell that needs to change certain words based on two command line arguments. I have made the replace function and everything works great, but I am stumped getting it to work with command line arguments.

Here is the main code: (replace function not included)

main = do 

text <- getContents

(command1:command2:_) <- getArgs
putStrLn (replace (read command1) (read command2) text)

So for intstance in the terminal I want to be able to type something like: "---> cat textfile.txt | ./replace oldword newword"

I know this code is close since I have seen others do it this way. O_o

Thanks for any help
