批处理文件删除除最新的10个文件外的所有文件 [英] batch file remove all but the newest 10 files

问题描述

批处理文件中包含以下内容:

I have the following in a batch file:

:REMOLDFILES
ECHO Removing files older than 14 days. >>%LOGFILE%
cd /d %BKUPDIR%
FOR /f "skip=14 delims=" %%A IN ('DIR /a:-d /b /o:-d /t:c %1*.zip ^2^>nul') DO IF EXIST "%%~fA" ECHO "%%~fA" >>%LOGFILE%
FOR /f "skip=14 delims=" %%A IN ('DIR /a:-d /b /o:-d /t:c %1*.zip ^2^>nul') DO IF EXIST "%%~fA" DEL "%%~fA" >>%LOGFILE%
FOR /f "skip=14 delims=" %%A IN ('DIR /a:-d /b /o:-d /t:c %1*.log ^2^>nul') DO IF EXIST "%%~fA" ECHO "%%~fA" >>%LOGFILE%
FOR /f "skip=14 delims=" %%A IN ('DIR /a:-d /b /o:-d /t:c %1*.log ^2^>nul') DO IF EXIST "%%~fA" DEL "%%~fA" >>%LOGFILE%
IF [%3]==[Y] GOTO SECONDBACKUPDIR
IF [%3]==[y] GOTO SECONDBACKUPDIR
GOTO END

我遇到的问题是，备份没有运行两周，最终由于删除了两周以上而删除了所有备份.

The problem I ran in to is that the backup was not running for a couple of weeks and ended up deleting all of my backups since they were over 2 weeks old.

我需要的是保留最近的10个最新备份.

What I need is for it to keep the last 10 latest backups.

有人知道我该怎么做吗?我没有写过一次，因为我对批处理文件不太熟悉.

Anyone have an idea how I would do that? I did not write this once since I'm not that familiar with batch files.

推荐答案

在按最后修改日期排序后，您可以使用FOR /F SKIP忽略最近修改的最后10个条目:

You could use FOR /F SKIP to ignore the last 10 most recently modified entries after sorting by last modified date:

for /f "skip=10 eol=: delims=" %%F in ('dir /b /o-d *.zip') do @del "%%F"
