To summarize, if you type scala on the command line without a file argument, the interpreter runs in interactive mode.

总的来说，如果你在命令行输入scala 而不输入文件名参数，解释器会运行在交互模式。

Following the example of the execution of the argument CMD, you could write a shell or interactive environment in Rexx (perhaps running either external utilities or built-in commands, much like bash).

按照参数cmd执行的例子，您可以在Rexx中写一个shell或者交互式的环境(或许会运行外部的实用程序或者内置命令，正如同bash)。

If you provide a filename as an argument, the monkeyrunner command runs the file's contents as a Python program; otherwise, it starts an interactive session.

如果您提供一个文件名作为运行参数，则monkeyrunner将视文件内容为Python程序，并加以运行；否则，它将提供一个交互对话环境。
