2-days old in Haskell

[TOPE KAREM]

I am very new to Haskell, and I am using this webpage as a learning source:
http://www.haskell.org/haskellwiki/Haskell_in_5_steps#Install_Haskell

I downloaded and instal GHC and it works as was said.

I tried to write my first Haskell program:

prelude> "Hello World!"
"Hello World, World!"

it works as said.

Then: (This is the problem)

I would like to create a source code and compile it using GHC compiler. I
opened a notepad and type this program:

main = putStrLn "Hello, Word!"

I saved this file as hello.hs in the same directory GHCi 6.6.1 was
installed.

When I tried to compile it as instucted on the webpage ( $ ghc  -o hello
hello.hs), I got this error message.

<interactive>: 1:0: parse error on input '$'

please what am I doing wrong.

Thank you and sorry for your time.
