使用变量在批处理文件中更改目录 [英] change directory in batch file using variable

问题描述

这是问题:

set Pathname = C:\Program Files
cd %Pathname%
pause

以上内容并未更改目录，正如我期望的那样.有人可以告诉我为什么吗?

The above doesn't change the directory, as I would expect. Can anybody please tell me why?

推荐答案

set语句不会按照您期望的方式处理空格；您的变量的名称实际上是Pathname[space]，等于[space]C:\Program Files.

The set statement doesn't treat spaces the way you expect; your variable is really named Pathname[space] and is equal to [space]C:\Program Files.

删除=符号两边的空格，并将值放在双引号中:

Remove the spaces from both sides of the = sign, and put the value in double quotes:

set Pathname="C:\Program Files"

此外，如果您的命令提示符未对C:\打开，则仅使用cd不能更改驱动器.

Also, if your command prompt is not open to C:\, then using cd alone can't change drives.

使用

cd /d %Pathname%

或

pushd %Pathname%

相反.
