Question

我必须使用Windows命令/批处理脚本替换文本文件（InputFile.txt）中的字符串。我找到了以下脚本（replace.cmd），但它没有给我准确的结果。

InputFile.txt：

1111 aaaa
2222 bbbb
$cc = 3333

我用来将replace.cmd替换为$cc = 3333的批处理脚本（cc = 4444）是：

@echo OFF 
setlocal enabledelayedexpansion

set "search=$cc = 3333"
set "replace=cc = 4444"
set "textfile=InputFile.txt"
set "newfile=OutputFile.txt"
(for /f "delims=" %%i in (%textfile%) do (
    set "line=%%i"
    setlocal enabledelayedexpansion
    set "line=!line:%search%=%replace%!"
    echo(!line!
    endlocal
))>"%newfile%"

运行代码后我得到的输出是：

1111 aaaa
2222 bbbb
3333=cc = 4444= 3333

应该是这样的：

1111 aaaa
2222 bbbb
cc = 4444

如果你想要一个像这样的vbscript的小技巧：

ng-class="{'blackout': $index==$rowIndex}"

@echo off
set "Data=some data .... $cc = 3333"
echo The data before replacing is "%Data%" & pause
set "String1=$cc = 3333"
set "String2=cc = 4444" 
Call :ReplaceString "%Data%" "%String1%" "%String2%"
echo The data after replacing is "%Data%" & pause & exit
::*************************************************************************************
:ReplaceString <Data> <String1> <String2>
(
    echo Wscript.echo Replace("%~1","%~2","%~3"^)
)>"%tmp%\%~n0.vbs"
for /f "delims=" %%a in ('Cscript /nologo "%tmp%\%~n0.vbs"') do ( set "Data=%%a" )
If Exist "%tmp%\%~n0.vbs" Del "%tmp%\%~n0.vbs"
exit /b

我们需要一位专家！当然，他/她知道如何做到这一点。

替换包含=符号的字符串很棘手。据我所知，你必须分成两个并测试这两个术语，或者如果要修复的字符串是固定的，请尝试

@echo off

set "search=$cc = 3333"
set "replace=cc = 4444"
set "textfile=InputFile.txt"
set "newfile=OutputFile.txt"

>"%newfile%" (
  for /f "delims=" %%i in (%textfile%) do (
    if "%%i" equ "%search%" (
      echo(%replace%
    ) else (
      echo(%%i
    )       
  )
)
exit/B

只需更改你的for循环：

@echo off

set "search=$cc = 3333"
set "replace=cc = 4444"
set "textfile=InputFile.txt"
set "newfile=OutputFile.txt"

>"%newfile%" (for /f "delims=" %%i in (%textfile%) do (
        If /I "%%i" Equ "%search%" (Echo=%replace%) Else (Echo=%%i)))
exit/B
