This article mainly introduces "how to implement the code of batch bat to judge whether a file has been updated in the last 5 minutes". In daily operation, it is believed that many people have doubts about how to implement batch bat to judge whether a file has been updated in the last 5 minutes. The editor consulted all kinds of materials and sorted out simple and useful methods of operation. I hope it will be helpful to answer the question of "how to implement batch bat to determine whether a file has been updated in the last 5 minutes"! Next, please follow the editor to study!

Background description of the problem:

The test program checks the time in a X.log text, such as 2008-11-1 12:00:00, because the log will be refreshed every 3 minutes, so the time will change. Now my idea is to compare the latest time caught by the program with the system time. If it takes more than 5 minutes, it means that the log of the system has not been generated (the system is dead), and then confirmed that it is dead. In a DB connected to Oracle, insert into the data of some fields into a table that is used to send alarm mail. I wonder if the bat document can be implemented.

The code is as follows:

@ echo off

Set SrcFile=D:/a.txt

For / f "skip=5 tokens=1-2 delims=" an in ('dir / tw "SrcFile%"') do (

Set "FileDay=%%a" b "

Goto: compare

)

: compare

Call: DateToMins% FileDay:~0,4%% FileDay:~5,2%% FileDay:~8,2%% FileDay:~11,2%% FileDay:~14,3% mFileDay

Call: DateToMins% date:~4,4%% date:~9,2%% date:~12,2%% time:~0,2%% time:~3,2% mToday

Set / a mMinus=mToday-mFileDay

If% mMinus% gtr 5 (

Echo "The system is down"

) else (

Echo "The system is running"

)

Pause

Goto: eof

DateToMins% yy%% mm%% dd%% hh%% mm% result

Setlocal ENABLEEXTENSIONS

Set yy=%1&set mm=%2&set dd=%3&set hh=%4&set nn=%5

If 1% y% LSS 200 if 1% y% LSS 170 (set yy=20%yy%) else (set yy=19%yy%)

Set / a dd=100%dd%%0,mm=100%mm%%0
