我在命令行中通过反复试验发现了这一点：

bundle --help show
  Usage:
    bundle show [GEM]

  Options:
        [--paths=List the paths of all gems that are required by your Gemfile.]
        [--no-color=Disable colorization in output]
    -V, [--verbose=Enable verbose output mode]

  Description:
    Show lists the names and versions of all gems that are required by your Gemfile. Calling show with [GEM] will list the exact location of that gem on your machine.

所以一般来说，输入bundle --help <command or utility name>
