How To Execute Native Commands In Java?

Question

I know very well how to execute commands via Runtime.getRuntime().exec(command) and handle the output, but this is VERY limited.

Take Windows for example (Vista specifically but that shouldn't matter).

How can I execute commands like 'echo', 'cd', 'md', 'rd', and any other command rooted inside of the cmd.exe through ProcessBuilder (or whatever class) in Java?

Answer 1

您只需调用cmd /c dir而不是Runtime.exec或ProcessBuilder中的dir或以其他方式在JAVA中运行外部应用程序。

Answer 2

Another trick is to leverage the Ant libraries and put together a programmed version of <exec ...> ( Ant Exec Task ). This also gives you access to all kinds of Ant-supported input/output processing and filtering.

This is not writing an Ant XML script here, but calling Ant from your code .
