どのrailsコマンドを打ってもUsageが表示されてしまいます

題名の通りなのですがどのどのrailsコマンドを打ってもUsageが表示されてしまいます。（rails, rails s, rails tなど）
現在Rails Tutorialを勉強しているのですが、10章をgit pushした後にこの症状に陥りました。考えられる原因としてはrails t をしないままpushしてしまった可能性があることですが関係あるのでしょうか？どなたかご教授願います。

sample_app (acount-activation) $ rails t
Usage:
  rails new APP_PATH [options]

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.
