这次注释没写多少，先跳过一些吧

::2.数据库过期备份删除
echo.
echo.
echo 二、正在清除过期的备份文件……

REM wscript.echo是vbs语法，相当于alert
REM >是特殊字符，所以放在 for 命令里面需要使用转义符号^>，包括^&也是转义的&
REM //Nologo屏弊输出：Prevent logo display: No banner will be shown at execution time
for /f "tokens=1,2,3 delims=-" %%a in (‘echo wscript.echo date-!bak_lot! ^>t~.vbs ^& cscript //nologo t~.vbs ^& del t~.vbs‘) do (
    set y=%%a&set m=%%b&set d=%%c
    if %%b lss 10 set m=0%%b
    if %%c lss 10 set d=0%%c
)

REM 此处-为字符串连接符
set DateE=!y!-!m!-!d!
for %%i in (1,2,3,4,5,6,7,8,9) do (

        REM dir /B 只显示文件名与扩展名，即使用空格式(没有标题信息或摘要)

                        del /q "%%a"
                    )
                )
            )
        ) else (
            echo %date:~0,10% %time:~0,8%  [!ora_net!__!ora_usr!]因为今天的备份没有成功，暂时不删除过期文件！
            echo %date:~0,10% %time:~0,8%  [!ora_net!__!ora_usr!]因为今天的备份没有成功，暂时不删除过期文件！>>!cur_dir!\delete.log
