Question

我正在尝试编写Windows批处理脚本，该脚本可以用递增的计数器替换文本。

我有一个带有电视频道的播放列表，我想在整个播放列表中替换每个频道编号。

我的播放列表具有以下结构：

#EXTM3U

#EXTINF:-1,ACS NETWORK TV
http://127.0.0.1:6878/ace/getstream?id=***&.mp4
#EXTINF:-1,Ani
http://127.0.0.1:6878/ace/getstream?id=***&.mp4
#EXTINF:-1,Boomerang HD (France)
http://127.0.0.1:6878/ace/getstream?id=***&.mp4
#EXTINF:-1,Boomerаng TV
http://127.0.0.1:6878/ace/getstream?id=***&.mp4

我要将#EXTINF:-1,替换为：

#EXTINF:-1, 1 
#EXTINF:-1, 2 
#EXTINF:-1, 3 
#EXTINF:-1, 4 
etc.

我的脚本具有以下结构：

findstr /c:"EXTINF" "C:\Users\home\Links\Desktop\TV-Playlist.m3u" | find /c /v "GarbageStringDefNotInYourResults" > C:\Users\home\Links\Desktop\1111.count
set /p VAR=< C:\Users\home\Links\Desktop\1111.count

for /L %%n in (1,1,%VAR%) do (

setlocal enableextensions disabledelayedexpansion
set "search=#EXTINF:-1,"
set "replace=#EXTINF:-1,!%%n! "
set "textFile=C:\Users\home\Links\Desktop\TV-Playlist.m3u"
for /f "delims=" %%i in ('type "%textFile%" ^& break ^> "%textFile%" ') do (
    set "line=%%i"
    setlocal enabledelayedexpansion
    >>"%textFile%" echo(!line:%search%=%replace%!
    endlocal
)
)

这是一种基于您的代码的解决方案：

@echo off
setlocal EnableExtensions DisableDelayedExpansion
set "PlayListFile=C:\Users\home\Links\Desktop\TV-Playlist.m3u"
if not exist "%PlayListFile%" goto EndBatch
set "Counter=1"
for /F "delims= eol=" %%I in ('type "%PlayListFile%" ^& break ^> "%PlayListFile%" ') do (
    set "Line=%%I"
    setlocal EnableDelayedExpansion
    if "!Line:#EXTINF:-1,=!" == "!Line!" (
        >>"%PlayListFile%" echo(!Line!
        endlocal
    ) else (
        >>"%PlayListFile%" call echo !Line:#EXTINF:-1,=#EXTINF:-1,%%Counter%% !
        endlocal
        set /A Counter+=1
    )
)
:EndBatch
endlocal

但是它会从文件中删除空行，因为 FOR 始终会忽略空行。

此代码还保留空行：

@echo off
setlocal EnableExtensions DisableDelayedExpansion
set "PlayListFile=C:\Users\home\Links\Desktop\TV-Playlist.m3u"
if not exist "%PlayListFile%" goto EndBatch

set "Counter=1"
set "TempFile=%TEMP%\%~n0.tmp"

(for /F "delims= eol=" %%I in ('%SystemRoot%\System32\findstr.exe /N /R "^" "%PlayListFile%"') do (
    set "Line=%%I"
    setlocal EnableDelayedExpansion
    set "Line=!Line:*:=!"
    if not defined Line (
        echo(
        endlocal
    ) else if "!Line:#EXTINF:-1,=!" == "!Line!" (
        echo(!Line!
        endlocal
    ) else (
        call echo !Line:#EXTINF:-1,=#EXTINF:-1,%%Counter%% !
        endlocal
        set /A Counter+=1
    )
))>"%TempFile%"

if not %Counter% == 1 move /Y "%TempFile%" "%PlayListFile%"
if exist "%TempFile%" del "%TempFile%"

:EndBatch
endlocal

有关此解决方案的详细信息，请参见How to read and print contents of text file line by line?

要了解所使用的命令及其工作方式，请打开命令提示符窗口，在其中执行以下命令，并非常仔细地阅读每个命令显示的所有帮助页面。

del /?
echo /?
endlocal /?
findstr /?
for /?
goto /?
if /?
move /?
set /?
setlocal /?

因此，如果我理解您的问题，并且我可以提出一个建议：

放置1用于处理计数器并重命名字符串，毕竟替换文件：

@echo off && setlocal enableextensions enabledelayedexpansion

set _m3u_file_in="%userprofile%\Links\Desktop\TV-Playlist.m3u"
set _m3u_file_out="%userprofile%\Links\Desktop\TV-Playlist_New.m3u"

set _cnt=0&& type nul >!_m3u_file_out!

for /f "tokens=* delims= " %%i in ('type !_m3u_file_in! ^|findstr /lbc:"#EXTINF:-" ^|findstr /r "[0-9][\,]" ') do (

    set "_old_=%%i"&& call set /a _cnt=!_cnt! + 1
    set "_new_=#EXTINF:-1,!_cnt!!_new:~10!"

)
echo/ Total lines replace: !_cnt!
move /y !_m3u_file_out! !_m3u_file_in!
