China DOS Union

I am a temporary network administrator in my unit. Backing up the data of the OA server is one of the daily work contents. Now I am copying all the folders and files that should be backed up on the OA server to a folder named with the current date (such as 2008-08-18) in full, and it is also a batch processing that is automatically executed every day. Since the content of the backup is getting larger and larger (a backup reaches 27.6G), I want to find a batch processing file that can automatically delete the backup directories older than five days before the backup (only keep the backup records of the past five days). Thanks in advance! My system is XP_SP1

```@echo off
>"%temp%\MyDate.vbs" echo dt=date()-5
>>"%temp%\MyDate.vbs" echo s=right(year(dt),4) ^& "-" ^& right("0" ^& month(dt),2) ^& "-" ^& right("0" ^& day(dt),2)
>>"%temp%\MyDate.vbs" echo wscript.echo s
for /f %%a in ('cscript /nologo "%temp%\MyDate.vbs"') do set FiveDay=%%a
for /f %%a in ('dir /b /ad') do (
if "%%a" lss "%FiveDay%" (
echo rd /s /q "%%a"
)
)
```

Thank you very much for the reply from friend HAT! Just now I tested the above batch file in the directory and it didn't work. I created a 000 folder in the root directory of drive D, and backed up the server files (including directories) to the folders from 2008-08-12 to 2008-08-18 generated in this directory. Now I just want to keep those after 2008-08-14. How to operate? I'm sorry, I'm a DOS newbie. Please be specific. Thanks again!

```batch
@echo off
>"%temp%\MyDate.vbs" echo dt=date()-5
>>"%temp%\MyDate.vbs" echo s=right(year(dt),4) ^& "-" ^& right("0" ^& month(dt),2) ^& "-" ^& right("0" ^& day(dt),2)
>>"%temp%\MyDate.vbs" echo wscript.echo s
for /f %%a in ('cscript /nologo "%temp%\MyDate.vbs"') do set FiveDay=%%a
for /f %%a in ('dir /b /ad "D:\000"') do (
if "%%a" lss "%FiveDay%" (
rd /s /q "%%a"
)
)
```

The test is still not successful... Please be more specific, thanks.

Save the code as xxx.bat. Double-click to run it and paste the result here.

>"%temp%\MyDate.vbs" echo dt=date()-5

>>"%temp%\MyDate.vbs" echo s=right(year(dt),4) ^& "-" ^& right("0" ^& month(dt),2) ^& "-" ^& right("0" ^& day(dt),2)

>>"%temp%\MyDate.vbs" echo wscript.echo s

for /f %%a in ('cscript /nologo "%temp%\MyDate.vbs"') do set FiveDay=%%a

for /f %%a in ('dir /b /ad "D:\000"') do (

  if "%%a" lss "%FiveDay%" (

    rd /s /q "D:\000\%%a"

  )

)

Such things already exist in the forum, so don't post or reply.

Can't see the picture. First, upload the picture to the forum, then put the link inside the img tag.

Come to earn some points to view higher-level ones...

Run the code on the 6th floor and post the result for us to see.

Did you see the picture? Please help

The code correction is as follows:

>"%temp%\MyDate.vbs" echo dt=date()-5

>>"%temp%\MyDate.vbs" echo s=right(year(dt),4) ^& "-" ^& right("0" ^& month(dt),2) ^& "-" ^& right("0" ^& day(dt),2)

>>"%temp%\MyDate.vbs" echo wscript.echo s

for /f %%a in ('cscript /nologo "%temp%\MyDate.vbs"') do set FiveDay=%%a

for /f "tokens=*" %%a in ('dir /b /ad "D:\000"') do (

  if "%%a" lss "%FiveDay%" (

    rd /s /q "D:\000\%%a"

  )

)

pause

Still no use, the running result is the same as I posted that day
