New to Rails have simple error.

I am following the guide here:

http://guides.rubyonrails.org/getting_started.html

I am on part 4.1 but when typing into the command line what it says to type I get that bin is not recognized as an internal or external command?

Rather than starting with the guides (which do not always include all
the necessary details) I suggest working through a good tutorial such
as railstutorial.org (which is free to use online). That should get
you going ok.

If you want an answer you would be better to tell us what operating
system you are running on exactly what you typed. Preferably
copy/paste from the terminal your command and the result, into a reply
here so that we know you have not introduced a typo here.
