Bundle vs Bundle Install

What is the difference between bundle and bundle install?

I have been using bundle install blindly, without understanding the difference with bundle.

@emacadie replies:

According to bundle –help, here are the options for bundle:

bundle COMMAND [--no-color] [--verbose] [ARGS]

The commands are install, update, package, exec and config. My guess is that “install” may be the default command.

bundle, bundle install
