Question

如何在批处理文件中的变量中存储目录名？

Answer 1

set dirname=c:/some/folder

echo %dirname%

REM retrieve the last letter of the folder 
REM and save it in another variable

set lastLetter=%dirname:~-1%

echo %lastLetter%

Answer 2

返回存储批处理文件的目录％〜DP0

％0是批处理文件的完整路径

set src= %~dp0
echo %src%

当我希望某些文件相对于我的批处理文件时，我已经使用过这个文件。

Answer 3

没有更多的精确度，很难帮助你......

也许你想要当前的目录？

set name=%CD%
echo %name%

Answer 4

使用设置命令。

示例：

rem Assign the folder "C:\Folder1\Folder2" to the variable "MySavedFolder"
set MySavedFolder=C:\Folder1\Folder2

rem Run the program "MyProgram.exe" that is located in Folder2
 %MySavedFolder%\MyProgram.exe
rem Run the program "My Second Program.exe" that is located in Folder 2 (note spaces in filename)
"%MySavedFolder%\My Second Program.exe"
rem Quotes are required to stop the spaces from being command-line delimiters, but the command interpreter (cmd.exe) will still substitute the value of the variable.

要删除变量，请不要为名称指定任何内容：

set MySavedFolder=

由于您位于批处理文件中，因此建议在文件末尾使用 setlocal 和 endlocal 来包含变量用法;这使您的环境变量成为批处理文件的本地变量，并且不会污染全局环境名称空间。

允许脚本确定其父文件夹目录名称：

@echo off
::setlocal enableextensions,enabledelayedexpansion
SET CDIR=%~p0
SET CDIR=%CDIR:\= %
FOR %%a IN (%CDIR%) DO (
  SET CNAME=%%a
)
echo %CDIR%
echo %CNAME%
pause

或者，更好的是：

@echo off
::setlocal enableextensions,enabledelayedexpansion
SET CDIR=%~p0
SET CDIR=%CDIR:~1,-1%
SET CDIR=%CDIR:\=,%
SET CDIR=%CDIR: =_%
FOR %%a IN (%CDIR%) DO SET "CNAME=%%a"
echo %CDIR%
SET CNAME=%CNAME:_= %
echo %CNAME%
pause
