batch-file - 通过批处理脚本拆分txt文件时，感叹号正在省略

Question

我是批处理脚本的新手，在这里我尝试将我的文本文件分成每 100 万行的块。块文件按我的预期生成，但在输出文件内容中我缺少感叹号（！），甚至在感叹号之后跳过了立即列。请帮助我将原始文件中的数据分成块！

@ECHO OFF
setLocal DisableDelayedExpansion

set limit=1000000
set feed_name=test.txt
set file=%Tgt_Dir%\%feed_name%
set lineCounter=1
set filenameCounter=1
set name=
set extension=


for %%a in (%file%) do (
    set "name=%%~na"
    set "extension=%%~xa"
)

setlocal enabledelayedexpansion
for /f "tokens=*" %%a in (%file%) do (
    set splitFile=!name!%date:~12,2%%date:~4,2%%date:~7,2%!filenameCounter!!extension!
    if !lineCounter! gtr !limit! (
        set /a filenameCounter=!filenameCounter! + 1
        set lineCounter=1
        echo Created !splitFile!.
    )
    echo %%a>> %Tgt_Dir%\!splitFile!

    set /a lineCounter=!lineCounter! + 1
)
endlocal

它是一个制表符分隔符文件。

您需要切换延迟扩展。

setlocal DisableDelayedExpansion 
for /f "tokens=*" %%a in (%file%) do (
    Set "line=%%a"
    setlocal  EnableDelayedExpansion 

        set splitFile=!name!%date:~12,2%%date:~4,2%%date:~7,2%!filenameCounter!!extension!

        echo(!line!>> %Tgt_Dir%\!splitFile!

    if !lineCounter! gtr !limit! (
        ENDLOCAL
        set /a filenameCounter+=1
        set lineCounter=1
        echo Created file
    ) ELSE ENDLOCAL
    set /a lineCounter=lineCounter + 1
)
