windows - 使用另一个批处理编辑批处理文件中的变量值

Question

现有的 A.bat ：

rem set variable pathVariable to appropriate value

set pathVariable=../Doc/English/MyDoc.htm

rem asd

从 B.bat 中，我需要使用包含空格的路径更新 pathVariable 的值，但是在用 %20 替换空格之后，运行 B.bat 后，A.bat 应该如下所示：

rem set variable pathVariable to appropriate value 

set pathVariable=C:/Program%20Files/XXX%20YYY/MyDoc.htm 

rem asd 

我试着玩这个并且可以写

@echo off
setlocal enabledelayedexpansion
set inputFile=A.bat
set outputFile=A_New.bat
set pathVar=../Doc/English/MyDoc.htm
set newPathVarSpace=C:/Program Files/XXX YYY/MyDoc.htm

set space=%%20
set newPathVarNoSpace=%newPathVarSpace: =!space!%
echo %newPathVarNoSpace%

for /f "tokens=1,* delims=" %%A in ( '"type %inputFile%"') do (
SET line=%%A
rem SET modified=!string:%pathVar%=%newPathVarSpace%!
SET modifiedLine=!line:%pathVar%=%newPathVarNoSpace%!

echo !modifiedLine! >> %outputFile%
)

该脚本有效，但它吃掉了我想保留的所有空白行。谢谢你的帮助。

试试下面的代码 -

一只蝙蝠

rem set variable pathVariable to appropriate value.
pathVariable=C:\Test

BAT

@echo off
    setlocal enableextensions disabledelayedexpansion

    set "config=.\A.bat"
    set "path=C:\Batch projects\Batch tests\bin\Debug App"

    for /f "tokens=*" %%l in ('type "%config%"^&cd.^>"%config%"'
    ) do for /f "tokens=1 delims== " %%a in ("%%~l"
    ) do if /i "%%~a"=="pathVariable" (
        >>"%config%" echo(pathVariable=%path%
    ) else (
        >>"%config%" echo(%%l
    )

    type "%config%"

    endlocal

现在转到A.BAT，用记事本打开它并检查 pathVariable 值，如下所示 -

C:\Batch projects\Batch tests\bin\Debug App
