如何在批处理文件中获得等效的dirname（）？ [英] How do I get the equivalent of dirname() in a batch file?

问题描述

我想从 .bat 文件中获取文件的父目录。所以，给定变量设置为C：\MyDir\MyFile.txt，我想得到C：\ MyDir。换句话说，相当于典型UNIX环境中的 dirname（）功能。这是可能吗？

I'd like to get the parent directory of a file from within a .bat file. So, given a variable set to "C:\MyDir\MyFile.txt", I'd like to get "C:\MyDir". In other words, the equivalent of dirname() functionality in a typical UNIX environment. Is this possible?

推荐答案

for %%F in (%filename%) do set dirname=%%~dpF

这将设置％dirname％到存储在％filename％中的文件名的驱动器和目录。

This will set %dirname% to the drive and directory of the file name stored in %filename%.

小心使用文件名包含空格。要么必须使用周围的引号设置：

Careful with filenames containing spaces, though. Either they have to be set with surrounding quotes:

set filename="C:\MyDir\MyFile with space.txt"

或者你必须在 / code> loop：

or you have to put the quotes around the argument in the for loop:

for %%F in ("%filename%") do set dirname=%%~dpF

任一方法都可以工作，但同时不会： - ）

Either method will work, both at the same time won't :-)
