如何顯示捆綁器命令和實用程序的幫助？

Question

bundle --help顯示列出命令（即安裝）和實用程序（即顯示）的幫助文件。如何查看有關如何使用特定命令或實用程序的詳細信息？

Answer 1

我發現這個通過在命令行中的試錯：

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. 

所以一般來說，類型bundle --help <command or utility name>
