Simplest: System.Environment:getArgs
import System.Environment
main = do
args <- getArgs
print args
http://haskell.org/ghc/docs/latest/html/libraries/base/System-Environment.html
Complex: System.Console.GetOpt
Example here: http://cgi.cse.unsw.edu.au/~dons/blog/2006/12/18#ph-3
http://haskell.org/ghc/docs/latest/html/libraries/base/System-Console-GetOpt.html
You can find these functions yourself with hoogle:
http://haskell.org/hoogle/
Searching for 'args' returns:
System. getArgs :: IO [String]
