命令提示符 - 如何添加一组路径仅用于执行批处理文件？ [英] Command Prompt - How to add a set path only for that batch file executing?

问题描述

基本上，我知道我可以通过我的控制面板和修改路径变量。但是，我想知道如果有就是要通过批处理编程的方式包括临时道路？这样，它的那批文件执行过程中仅使用。我不想让人们去和修改他们的路径变量只是用我的批处理文件。

Basically, I know I can go through my control panel and modify the path variable. But, I'm wondering if there is a way to through batch programming have a temporary path included? That way it is only used during that batch file execution. I don't want to have people go in and modify their path variables just to use my batch file.

推荐答案

就像任何其他的环境变量，以 SET ：

Just like any other environment variable, with SET:

SET PATH=%PATH%;c:\whatever\else

如果你想拥有内置的第一个一点点的安全检查，检查是否新路径存在第一：

If you want to have a little safety check built in first, check to see if the new path exists first:

IF EXIST c:\whatever\else SET PATH=%PATH%;c:\whatever\else

如果你想，要成为本地该批处理文件，使用 SETLOCAL ：

If you want that to be local to that batch file, use setlocal:

setlocal
set PATH=...
set OTHERTHING=...

@REM Rest of your script

仔细 SETLOCAL / ENDLOCAL 读取文档，并看看在该网站上的其他参考 - 功能是pretty有趣也和语法是棘手的。

Read the docs carefully for setlocal/endlocal , and have a look at the other references on that site - Functions is pretty interesting too and the syntax is tricky.

借助语法页面应该让你开始的基本知识。

The Syntax page should get you started with the basics.
