Now we need to process log files. The naming rule of the file name is as follows:

.log
Example)
D:\tabiplaza\yado\debug\20080522000200.log

Batch processing requirements:
1. Delete files that are six months ago.
2. Classify files that are five months ago. Put each file into the corresponding folder according to the month, and name the folder with the month.
For example: D:\tabiplaza\yado\debug\20080522000200.log -> folder: 200805

Since I am initially exposed to batch processing and basically at the entry-level state, I ask the moderator and all the experts to help come up with ideas! Thank you very much!
(In addition, I didn't find any results when searching, and it may also be that the search keywords are incorrect. I hope to get some guidance!)

Assuming that the logs from 5 months ago have been classified, do we need to check if the files in the judgment classification folder exceed 6 months when processing next month?

Needed, my idea is:
If we execute the batch processing next month, first, judge according to the file name. If it is a folder from six months ago, directly delete the entire folder.
For example: Now it is May 2008, then the folder 200712 I will directly delete it

Run in the D:\tabiplaza\yado\debug folder,
Not tested...


@echo off&setlocal enabledelayedexpansion

for /f "tokens=1,2 delims=:-\/. " %%a in ("%date%") do (

   set /a yy=%%a,mm=100%%b%%100-5

)

if %mm% leq 0 set /a nn=1

set /a m=(12+mm)%%12,y=yy-nn

if %m% equ 0 set m=12

set m=0%m%

set yy=%y%%m:~-2%

for /f "delims=" %%a in ('dir/b/ad') do if %%a leq %yy% rd/q/s "%%a"

for /f "delims=" %%a in ('dir/b/a-d *.log') do (

   set "str=%%~nxa"

   set "str=!str:~0,6!"

   if !str! leq %yy% (del/q "%%a") else (

      if not exist !str!\ md !str!

      move "%%a" "!str!"

    )

)

pause

Thanks a lot. I'm testing it, but I encountered some problems. I'll continue to ask for advice.

1. I saved it in D:\tabiplaza\yado\debug and named it debug.bat.
2. I want it to output some prompt information, but the black screen of cmd always flashes and disappears. Why is that?

Hehe, I feel really stupid, but there's no way. Learning is always such a process. Please give me more advice. I'm very grateful!

It flashed and then disappeared. There was an error in the code. Sorry, I carelessly wrote %yy% as %yy%%. Now it has been corrected, let's try again.

When running to the line "for /f "delims=" %%a in ('dir/b/ad') do if %%a leq %yy%% rd/q/s "%%a"", an error occurs:
The syntax of the command is incorrect.
The reason is under investigation

The error when running after adding the two operation variables %yy% later is:
6! was unexpected at this time.
It seems there is still an error in the last if sentence. Hehe, take some time to look again, thank you

Hehe, yes! Now it can be classified, thanks!

Boss, but the function to delete files that have exceeded the time has not been implemented, hehe

I can test it!
if !str! leq %yy% (del/q "%%a")
Is this sentence for deleting files?

Ah? No way, when I tested, I always created the corresponding folder and put the files in it (including those from six months ago). I think it might be a difference in directory structure?

The directory structure here is:
Files and folders are placed under D:\tabiplaza\yado\debug\
Is that so?

I created the following log files in the abcd folder.
Then I ran the code from floor 4.
In the abcd folder, only the 200801-----2008-05 folder remains, and the corresponding files are inside.
There are no longer any files starting with 2007. Is that incorrect?
:


200701dfjg.log

200702dfgs.log

200703fhhhgh.log

200710sfysh.log

200711sdfhsh.log

Fainted, it turns out the directory structure is different. Hehe, it's my fault for not being able to understand the code well. I'm a newbie, newbie.

Boss, two questions:
1. The bat files are placed in D:\tabiplaza\yado\debug, which should be correct!
2. What's the directory path of your abcd folder?

Hey, if I weren't in a hurry to get it done, I would definitely wait until I can fully understand the code before asking you carefully!
