更改Java中的当前目录以实现“cd”命令在linux [英] Changing the current directory in Java to implement "cd" command in linux

问题描述

我试图构建一个命令行解释器，在linux中实现cd命令。我不知道如何的功能，假设做这个工作。

I'm trying to build a command line interpreter that implements "cd" command in linux. I don't know how the function that suppose to do that shoud work.

我知道这个问题已经在这里回答了：
在Java中更改当前工作目录？

I know that this question has already been answered here: Changing the current working directory in Java?

但是我是Java的新手，关于这个，仍然没有得到如何新的文件（父，路径）将帮助我改变我的目录。任何帮助？

But I'm new to Java and I read alot about this and still don't get how new File(parent, path) would help me change my directory. Any help please?

推荐答案

我使用一个全局变量保存我当前方向的路径。 cd 只是更改它，所有其他命令相应地使用/修改它。没有什么简单的猜想。

I used a global variable that holds the path of my current direction. cd would just change it and all other commands use/modify it accordingly. Nothing simpler I guess.
