Three things:

1. The $ is just a sample prompt, a convention used to indicate what
   you should typed.

2. The command is for a shell (CMD or COMMAND), not GHCi.

3. The command is wrong!  for Windows it should be "ghc -o hello.exe
   hello.hs".  Assuming you aren't knowledgable yet on the differences
   between Windows and Unix programming environments, it might be a good
   idea to pick another tutorial.
