更新后在行尾创建空格

Question

我正在尝试替换属性文件中的占位符。因此，替换有效，但它总是在每行后面添加一个空格：

@echo off

REM Loop through all files in both specified directories (non-recursively)
for %%D in ("%propertiesDir1%" "%propertiesDir2%") do (
    for %%F in ("%%D\CTL*.properties" "%%D\h*.properties") do (
        if exist "%%F" (
            echo Processing: %%F

            REM Read each line of the file and update it in place
            for /f "usebackq delims=" %%L in ("%%F") do (
                set "line=%%L"

                REM Check if the line contains the target string and replace it if found
                echo !line! | findstr /c:"%targetString%" >nul
                if not errorlevel 1 (
                    REM Replace the target string with the new value directly in the file
                    set "line=!line:%targetString%=%myValue%!"
                )

                echo !line! >> "%%F.new"
            )

            REM Replace the original file with the new content
            move /y "%%F.new" "%%F" >nul
            echo Update completed for: %%F

        ) else (
            echo File not found: %%F, skipping...
        )
    )
)

例如：

替换前的test.properties：

myCode=代码

替换后的test.properties：

myCode=代码（空格）

为什么会出现这种情况？我该如何解决它？

斯蒂芬的解决方案对我有用：

(echo !line!) >>"%%F.new"
