脚本/ rails与rails

Question

我正在写一个教程，其中我演示了一些rails命令。在我的机器上，rails和script/rails运行得一样好。有没有“首选”的形式？这两种方法中哪一种更通用？

Answer 1

当您在Rails 3应用程序中运行rails可执行文件时，它将查找script/rails文件，如果存在，则使用您传递给rails的参数执行该文件。

您使用rails而不是script/rails的原因通常归结为这样一个事实:它更短。

还有一件事需要注意，在Rails2应用程序中，还有rails c命令，它将在当前目录中生成一个名为c的应用程序文件夹。使用script/rails，这种情况就不会发生；相反，它会抱怨script/rails不存在。

Answer 2

在rails 3中，应该只有Rails。

Answer 3

"rails“将显示所有关于脚本用法的信息：

             new application called MyApp in "./my_app"

In addition to those, there are:
