Batch BAT Determines whether a file has been updated in the last 5 minutes by the code _dos/bat

Problem Background Description:

The test program looks at the time in a X.log text, similar to the format of 2008-11-1 12:00:00, because the log is refreshed every 3 minutes, so the time will change, and now my idea is to use the program to catch the latest is the maximum time and system time to do, more than 5 minutes, It means that the system log has not been regenerated (the system is dead), and then after confirming that it is dead, in a DB connected to Oracle, insert some field data into a table to send alarm mail. I don't know if the bat document will be implemented.

Copy Code code as follows:

@echo off
Set Srcfile=d:/a.txt
for/f "skip=5 tokens=1-2 delims="%%a in (' Dir/tw "%srcfile%" ') Do (
Set "Fileday=%%a%%b"
Goto:compare
)
: Compare
Call:D atetomins%fileday:~0,4%%fileday:~5,2%%fileday:~8,2%%fileday:~11,2%%fileday:~14,3% MFileDay
Call:D atetomins%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
