Expanding from Andriy M，是的你可以从一个文件中做到这一点，即使是多行的

Expanding from Andriy M, and yes you can do this from a file, even one with multiple lines

@echo off
setlocal EnableExtensions EnableDelayedExpansion
set "INTEXTFILE=test.txt"
set "OUTTEXTFILE=test_out.txt"
set "SEARCHTEXT=bath"
set "REPLACETEXT=hello"

for /f "delims=" %%A in ('type "%INTEXTFILE%"') do (
    set "string=%%A"
    set "modified=!string:%SEARCHTEXT%=%REPLACETEXT%!"
    echo !modified!>>"%OUTTEXTFILE%"
)

del "%INTEXTFILE%"
rename "%OUTTEXTFILE%" "%INTEXTFILE%"
endlocal

感谢 David Nelson，我已经更新了脚本，因此它不再具有硬编码值.

Thanks David Nelson, I have updated the script so it doesn't have the hard coded values anymore.
