从USB驱动器运行批处理文件时盘符发生变化 [英] Running batch file from USB drive when drive letter changes

问题描述

所以，我做了一个批处理脚本，并执行多个可移植程序（例如，prog1.exe，prog2.exe等）。问题是，每当我将USB硬盘连接到另一台计算机，驱动器盘符更改，运行我.bat文件时，给我的错误。请大家帮我想想办法。谢谢你。

So, I have made a batch script and it executes multiple portable programs (e.g., prog1.exe, prog2.exe, etc). The problem is whenever I connect the USB drive to another computer, the drive letters change, giving me errors when running my .bat file. Please help me find a solution. Thank you.

推荐答案

％〜D0 为您提供了当前驱动器盘符（包括冒号）。如果批处理文件中所包含的USB驱动器上，就可以使用它。

%~d0 gives you the current drive letter (including the colon). If the batch file's contained on the USB drive, you can use that.

所以，举例来说，而不是

So, for instance, instead of

E:\PortablePrograms\ProgramName.exe

您会写

%~d0\PortablePrograms\ProgramName.exe

...或者你可以做这样的事情。

... or you could do something like this

::change directory to the script's directory's drive
pushd %~d0
::navigate from the drive to the relevant path(s)
cd PortablePrograms
::execute any programs
ProgramName.exe
SecondProgramName.exe
::just because I like to pair my pushes with pops; not required
popd
