China DOS Union

I want to use batch processing under DOS to copy c:\log\log.log to d:\logbak\log.log every three minutes. How to achieve it!

Using sleep :

@echo off
:cycle
copy /y c:\log\log.log d:\logbak\log.log
sleep 180
goto cycle

The disadvantage of the program on the 2nd floor is that it cannot achieve background copying, which doesn't seem to meet the LZ's requirements, oh
I think the LZ's goal should be to design such a program: call interrupt handling, reside in memory, monitor in real time, copy in the background, and be able to continue running other programs. This is similar to Windows' Task Scheduler. Batch processing is difficult to do, but C language can.

@echo off
copy c:\log\log.log d:\logbak\log.log

set mytime=%time:~3,2%
set wintime=%time:~0,3%

:t
set /A mytime+=3
if "%mytime%" GTR 60 set /A mytime-=60
if "%mytime%" == "60" set /A mytime=00

:m
set times=%time:~0,5%
set ti=%times:~3%
if "%ti%" == "00" set wintime=%time:~0,3%
if "%wintime%%mytime%" == "%times%" copy c:\log\log.log d:\logbak\log.log && goto t
goto m

I also post one
@echo off :start copy /y c:\log\log.log d:\logbak\log.log choice /T 180 /d y goto start

Such a useful command choice

But the cmd in my XP doesn't have this command.

I don't know why?

It's available in 2003

Just copy it over. Choice seems to have two versions.

For XP, just use ping.
ping 1.1.1.1 -w 3000 -n 1
Set the number of times n to 1, which can make the time as precise as possible.

This method is good!

May I ask how you do the {copy to slip}? I want to learn it

Add code code Example:
[code]
@echo off
:start
copy /y c:\log\log.log d:\logbak\log.log
choice /T 180 /d y
goto start
[/code]

What is the function of ""? ---------------------------------------- Oh, I got it.

那我是菜菜鸟，pengpeng能不能传个C的样本上来我:P好好学学？谢谢阿！

那 I'm a newbie, can pengpeng upload a C sample for me to learn from :P? Thanks ah!

Not bad, bad~ received

They are all experts, let's study!
