如何使用 .bat 获得系统启动时间？ [关闭]

Question

我需要使用批处理脚本从我网络中的所有计算机获取系统正常运行时间信息。

Answer 1

这是在独立机器上获得正常运行时间的一种方法。

您可以使用psexec 在远程机器上运行它，或者可能更改 wmic 以从远程机器中提取信息。

@echo off
for /f "delims=" %%a in ('wmic OS Get LastBootUpTime ^| find "."') do set up=%%a
for /f "delims=" %%a in ('wmic OS Get localdatetime  ^| find "."') do set dt=%%a

set beg=%up:~0,4%-%up:~4,2%-%up:~6,2%T%up:~8,2%-%up:~10,2%-%up:~12,2%-%up:~15,3%
set end=%dt:~0,4%-%dt:~4,2%-%dt:~6,2%T%dt:~8,2%-%dt:~10,2%-%dt:~12,2%-%dt:~15,3%


call :TimeDifference uptime %end% %beg% 

echo %beg%
echo %end%
echo Uptime is: %uptime%


pause
goto :eof

:TimeDifference Return_Variable Start_Date_Time Stop_Date_Time
:: Version -0 2009-12-25 Frank P. Westlake
:: Calculate the difference in time between parameter 2 and parameter 3
:: and return the values in the variable named by parameter 1.
::
:: Parameters 2 and 3 are ISO8601 DATE/TIMEs of the format
::
::     YYYY-MM-DDThh-mm-ss
::
:: where '-' may be any of '/:-., '.
::
:: RETURN:
:: The variable named by %1 will be set with a string containing each of

::
::   DAYS HOURS MINUTES SECONDS MILLISECONDS
::
:: EXAMPLE: Call :TimeDifference diff "2009-12-01T 1:00:00.00" "2009-11-30T13:00:00.01"
::          Sets variable "DIFF=0 12 0 0 10"
