Ask. What is the file name you generated? 20080812? Like that?

The top floor has a description
2008-08-18

Now suppose all the files in your folder are generated by date. (I don't care what the file names are)

Don't mess with creating your own folders randomly. : ) Hehe.

Then here's a simple code. But it's not very safe, you need to ensure that the files are not messed up.

Here's a one - sentence code.

"skip" means skip the first 5.

for /f "skip=5 tokens=* " %%i in ('dir /b /o-d /ad-h-s') do echo The file name to delete is: , syntax format: 

This code can be tested. If it meets your conditions, then you can take out the things after rd...

Remember, the above conditions need to be met under the condition that you said a backup folder is created every day. Moreover, there should be no other folders in this backup folder. Only backup files can exist.

Translate an old post for you. I don't know if the time format matches yours

@echo off

set TT=5&set "ph=d:\000"

for /f "tokens=1-3 delims=-/\:. " %%i in ("%date%") do set /a p1=%%i,p2=100%%j%%100,p3=100%%k%%100

    if %p3% gtr %TT%  goto ppp

:nxt

set/a p2-=1

   if %p2% equ 0 set/a p1-=1,p2=12

   for /f "tokens=%p2%" %%i in ("31 %pN2% 31 30 31 30 31 31 30 31 30 31") do set/a p3+=%%i

Are VBS files runnable under Windows 98, XP, 2000, 2003 systems?

HAT's automatic delete files N days ago VBS is somewhat incomprehensible

--------------------------------------------------------------------------------
I want to automatically delete files older than 15 days in the directory rardata under win2000. How to modify it? Forfile is more convenient under win2003.




@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"
)
)

```
@echo off
setlocal enabledelayedexpansion
set SrcDir=D:\rardata
>"%tmp%\MyDel.vbs" echo dt=date()-15
>>"%tmp%\MyDel.vbs" echo s=right(year(dt),4) ^& right("0" ^& month(dt),2) ^& right("0" ^& day(dt),2)
>>"%tmp%\MyDel.vbs" echo wscript.echo s
for /f %%a in ('cscript /nologo "%tmp%\MyDel.vbs"') do set DateFlag=%%a
for /f "tokens=*" %%a in ('dir /s /b /a-d "%SrcDir%"') do (
set FileDate=%%~ta
set FileDate=!FileDate:-=!
set FileDate=!FileDate:~0,8!
if !FileDate! lss %DateFlag% (
del /f /q "%%a"
)
)
```

The format of %data% in win2000 is: Sunday 2008-08-24

Still don't know how to modify this? You can take a look at the help of set.

@echo off

setlocal enabledelayedexpansion

set SrcDir=D:\rardata

>"%tmp%\MyDel.vbs" echo dt=date()-15

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

>>"%tmp%\MyDel.vbs" echo wscript.echo s

for /f %%a in ('cscript /nologo "%tmp%\MyDel.vbs"') do set DateFlag=%%a

for /f "tokens=*" %%a in ('dir /s /b /a-d "%SrcDir%"') do (

  set FileDate=%%~ta

  set FileDate=!FileDate:-=!

  set FileDate=!FileDate:~4,10!

  if !FileDate! lss %DateFlag% (

    del /f /q "%%a"

  )

)

Thanks for HAT's patient guidance!

Now I'm looking at the content of the delay variable, and there's really a lot of batch processing content.

If the batch processing to be executed is not stored in the D:\rardata directory, the dir after for /f "tokens=*" %%a in ('dir /s /b /a-d "%SrcDir%"' should specify the directory path of the file to be deleted, right?

What do these two sentences do?
s=right(year(dt),4) ^& right("0" ^& month(dt),2) ^& right("0" ^& day(dt),2)

wscript.echo s

Batch scripts can be placed anywhere because the data directory is specified here:
set SrcDir=D:\rardata

s=right(year(dt),4) ^& right("0" ^& month(dt),2) ^& right("0" ^& day(dt),2)
wscript.echo s
Call VBS to get the formatted system date:

I've finished this. The method used is relatively old-fashioned

set usbdisk=E:

set befor2days=

set nowdate=



echo wscript.echo dateadd("d",-2,date) >%tmp%\tmp.vbs

for /f "tokens=1,2,3* delims=-" %%i in ('cscript /nologo %tmp%\tmp.vbs') do set y=%%i

for /f "tokens=1,2,3* delims=-" %%i in ('cscript /nologo %tmp%\tmp.vbs') do set m=%%j

for /f "tokens=1,2,3* delims=-" %%i in ('cscript /nologo %tmp%\tmp.vbs') do set d=%%k

if %m% LSS 9 set m=0%m%

if %d% LSS 9 set d=0%d%

set/a befor2days=%y%%m%%d%



echo wscript.echo dateadd("d",-0,date) >%tmp%\tmp.vbs

for /f "tokens=1,2,3* delims=-" %%i in ('cscript /nologo %tmp%\tmp.vbs') do set y=%%i

for /f "tokens=1,2,3* delims=-" %%i in ('cscript /nologo %tmp%\tmp.vbs') do set m=%%j

for /f "tokens=1,2,3* delims=-" %%i in ('cscript /nologo %tmp%\tmp.vbs') do set d=%%k

if %m% LSS 9 set m=0%m%

if %d% LSS 9 set d=0%d%

set/a nowdate = %y%%m%%d%



........Omit in the middle, the date is sorted into the format of 20080825 and used as the directory.



dir %usbdisk%\ /ad/on/b>%tmp%\usbdir.tmp

for /f "delims=" %%i in (%tmp%\usbdir.tmp) do (

			if %%i lss %befor2days% (

															rd /s/q %usbdisk%\%%i

															)

下面 is to judge whether it is 2 days ago. If it is, delete it; if not, skip.

Hope the experts don't laugh at me. The solution I came up with is a bit clumsy.

We often need to search for files in daily work. When it comes to the most powerful file search tool under Linux, find is definitely the one. find can filter files from file names, reading and modification times, sizes, types, etc., and can complete almost all daily search needs.

Let's take a simple example:

find /tmp/ -name 'galeki*'

This means finding files starting with "galeki" in the /tmp directory. -name indicates that it is filtering by file name. Isn't it very simple and clear? In addition to file names, find has more powerful filtering conditions:

1. Time:

Parameter Meaning
-atime n Files whose last access time was within n*24 hours Using Linux's find is simple
-ctime n Files whose last status change was within n*24 hours
-mtime n Files whose last modification time was within n*24 hours
-newer file Files that are newer than the file referred to by file

None of the tests succeeded..

The time format of 2000 is:

Current date: 2008-10-20 Monday

Hope some expert can give a complete one
