批量标准化文件路径 [英] Normalize file path in batch

问题描述

是否有一种方法可以从绝对文件路径中批量解析.?例如，以下批处理脚本应输出 C:\ Users \ xyz \ other \ abc.txt :

Is there a way to resolve the .. from an absolute file path in batch? For example, the following batch script should output C:\Users\xyz\other\abc.txt:

REM Project dir is an absolute path, for example, C:\Users\xyz\project\
SET projectDir=%~1

REM Target file is a path relative to the project dir, for example, ..\other\abc.txt
SET target=%~2

REM Concatenate paths. This becomes C:\Users\xyz\project\..\other\abc.txt
SET absoluteTarget=%projectDir%%target%
SET absoluteTargetClean=...
echo %absoluteTargetClean%

absoluteTarget 变量引用现有文件.

我需要相同的目录而不是文件.您可以使用相同的方法来实现这一目标吗?

I need the same for a directory instead of the file. Can you use the same way to achieve that?

推荐答案

我想知道，谁能想到一个像 C:\ Users \ xyz \ project \ .. \ other \ abc.txt这样的路径?，但我们开始:

I wonder, how anyone ever could come up with a path like C:\Users\xyz\project\..\other\abc.txt, but here we go:

SET "absPath=C:\Users\xyz\project\..\other\abc.txt"
for %%i in ("%absPath%") do SET "absPathClean=%%~fi"
echo %absPathClean%

适用于文件和文件夹.
