在批处理文件中查找文件的修改日期是否早于N小时，如果不是，则发送电子邮件 [英] Find out if file's modified date is older than N hours in Batch file and send email if not

问题描述

我认为这篇文章正是我所期待的：

然而，它似乎并没有工作。任何人都可以帮忙吗？

我有许多服务器上运行的应用程序，每隔一段时间崩溃。当它崩溃时，它不再写入它自己的日志文件。因此，如果我可以写一个bat文件来检查日志文件是否最近没有被修改，它可以给我发送一个警报。不幸的是，我需要知道这个文件是否在过去的4到5个小时内发生了变化。知道文件是否在最后一天内被修改是不够好的。谢谢！

解决方案

试试这个，解释是在代码中：

  @ECHO OFF& SETLOCAL 
 ::初始化
 CALL：GetInternational 
 
 ::示例
 SETdate1 = Fr 08/30/2013
 SETtime1 = 19：50：52,17
 
：获取秒
调用：GetSecs％date1％％time1 ％sec1 
 call GetSecs％date％％time％sec2 
 
 ::计算分钟
 set / a elapsedMin =（sec2-sec1）/ 60
回声此答案是％elapsedMin％分钟（S）旧（CET）。 
 
 ::计算小时
 ::请注意，cmd不能计算十进制数字，例如： 1.23 
 set / a elapsedHr =（sec2-sec1）/ 3600
回答此答案是％elapsedHr％小时（CET）。 
 
 :: goto文件结尾
 goto：eof 
 
：GetInternational 
 ::通过读取注册表设置
'for / ftokens = 1,2 *%% a in（'reg queryHKCU\Control Panel\International'）do set%% a = %% c
 goto：eof 
 $ b $ GetSecsdateIntimeInsecondsOut 
 :: Output：自1970年1月1日以来的秒数00:00:00 
 setlocal 
 setdateIn = ％〜1
 for / ftokens = 2%% i in（％dateIn％）do setdateIn = %% i
 for / ftokens = 1-3 delims =％sDate％%% a in（％dateIn％）do（
 if％iDate％== 0 set / a mm = 100 %% a %% 100，dd = 100 %% b %% 100，yy = 10000 %% c %% 10000 
 if％iDate％== 1 set / a dd = 100 %% a %% 100，mm = 100 %% b %% 100，yy = 10000 %% c %% 10000 
 if％iDate％== 2 set / a yy = 10000 %% a %% 10000，mm = 100 %% b %% 100，dd = 100 %% c %% 100 
）
 for / ftokens = 1-3 delims =％sTime %% sDecimal％%% in（％〜2）do（
 sethh = %% a
 setnn = %% b
 setss = %% c
）
 if 1％hh％lss 20 set hh = 0％hh％
如果％nn：〜2,1％等于p如果％hh％neq1 2（设置hh = 1％hh％和设置/ hh- = 88）
如果％nn：〜2,1％equaif％hh％equ12 设置hh = 00
如果％nn：〜2,1％geqa设置nn =％nn：〜0.2％
 set / a hh = 100％ hh %%% 100，nn = 100％nn %%% 100，ss = 100％ss %%% 100 
 set / az = 14-mm，z / = 12，y = yy + 4800-z， M =毫米+ 12 * Z-3，J = 153 * M + 2，当J = J / 5 + DD + Y * 365 + Y / 4-γ/ 100 + Y / 400-2472633，当J = J * 86400 + hh * 3600 + nn * 60 + ss 
 endlocal& set％〜3 =％j％
 goto：eof

I thought this post was exactly what I was looking for:

Find out if file is older than 4 hours in Batch file

However, it doesn't seem to work. Can anyone help?

I have an aplication running on many servers that crashes every once and a while. When it crashes, it no longer writes to its own log file. Therefor, if I can write a bat file to check if that log file has not been modified recently, it can email me an alert. Unfortunately, I need to know if this file has been changed within the last 4 to 5 hours. Knowing if the file was modified within the last day is not good enough. Thanks!

解决方案

try this, explanation is in the code:

@ECHO OFF &SETLOCAL
:: Initialisation
CALL :GetInternational

:: Example
SET "date1=Fr 08/30/2013"
SET "time1=19:50:52,17"

:: Get the seconds
call :GetSecs "%date1%" "%time1%" sec1
call :GetSecs "%date%" "%time%" sec2

:: calculate the minutes
set /a elapsedMin="(sec2-sec1)/60"
echo This answer is %elapsedMin% minute(s) old (CET).

:: calculate the hours
:: please note, cmd can't calculate decimal numbers, e.g. 1.23
set /a elapsedHr="(sec2-sec1)/3600"
echo This answer is %elapsedHr% hour(s) old (CET).

:: goto end of file
goto:eof

:GetInternational
:: Sets a bundle of variables by reading the registry settings
for /f "tokens=1,2*" %%a in ('reg query "HKCU\Control Panel\International"') do set "%%a=%%c"
goto :eof

:GetSecs "dateIn" "timeIn" secondsOut
::  Output:  Seconds elapsed since 1th Jan. 1970 00:00:00
setlocal
set "dateIn=%~1"
for /f "tokens=2" %%i in ("%dateIn%") do set "dateIn=%%i"
for /f "tokens=1-3 delims=%sDate%" %%a in ("%dateIn%") do (
  if %iDate%==0 set /a mm=100%%a%%100,dd=100%%b%%100,yy=10000%%c%%10000
  if %iDate%==1 set /a dd=100%%a%%100,mm=100%%b%%100,yy=10000%%c%%10000

)
for /f "tokens=1-3 delims=%sTime%%sDecimal% " %%a in ("%~2") do (
  set "hh=%%a"
  set "nn=%%b"
  set "ss=%%c"
)
if 1%hh% lss 20 set hh=0%hh%
if "%nn:~2,1%" equ "p" if "%hh%" neq "12" (set "hh=1%hh%" &set /a hh-=88)
if "%nn:~2,1%" equ "a" if "%hh%" equ "12" set "hh=00"
if "%nn:~2,1%" geq "a" set "nn=%nn:~0,2%"
set /a hh=100%hh%%%100,nn=100%nn%%%100,ss=100%ss%%%100
set /a z=14-mm,z/=12,y=yy+4800-z,m=mm+12*z-3,j=153*m+2,j=j/5+dd+y*365+y/4-y/100+y/400-2472633,j=j*86400+hh*3600+nn*60+ss
endlocal &set "%~3=%j%"
goto :eof
