AWS に登録し、cloud9のIDEを用いて、ruby on rails tutorials を一から取り掛かっています。
gem failを用意し、チュートリアル の1.3.2のrails serverの所まで進みました。
ここで、
$ cd ~/environment/hello_app/
$ rails server
をうち、serverを起動しました。その後、アドバイス的な何かで、rails serverコマンドの実行は別のターミナルタブで行うことをオススメします。とチュートリアル に書いてあり、一旦最初のタブのserverをコントロールcで終了し、新しいタブで、チュートリアルに書いてある指示どうりに進めたら、新たなタブに
ec2-user:/environment $ cd first_app/environment $ rails server
bash: cd: first_app: No such file or directory

Description:
The 'rails new' command creates a new Rails application with a default
directory structure and configuration at the path you specify.
You can specify extra command-line arguments to be used every time 'rails new' runs in the .railsrc configuration file in your home directory. Note that the arguments specified in the .railsrc file don't affect the defaults values shown above in this help message.
Example:
rails new ~/Code/Ruby/weblog
This generates a skeletal Rails installation in ~/Code/Ruby/weblog.
ec2-user:~/environment $
このように表示され、初心者のため次に進んでいいのかよくわからなくなってしまいました。
今、どういった状況で何が起きてしまったのかどなたか教えていただけると嬉しいです。
また、この状況を解決し、次に進むにはどんな処理をすれば良いのか、どんなコマンドを打てばよいのか、教えてください。
