Bat脚本学习-6：Oracle自动备份还原脚本

::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!

        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)
