是否有一种内置的方法来测量Windows命令行上命令的执行时间?

“精益和平均”计时器与区域格式,24小时和混合输入支持 调整Aacini的替换方法体,没有IF,只有一个FOR(我的区域修复)
1:文件timer.bat放置在%PATH%或当前目录的某处
@echo off & rem :AveYo: compact timer function with Regional format, 24-hours and mixed input support
if not defined timer_set (if not "%~1"=="" (call set "timer_set=%~1") else set "timer_set=%TIME: =0%") & goto :eof
(if not "%~1"=="" (call set "timer_end=%~1") else set "timer_end=%TIME: =0%") & setlocal EnableDelayedExpansion
for /f "tokens=1-6 delims=0123456789" %%i in ("%timer_end%%timer_set%") do (set CE=%%i&set DE=%%k&set CS=%%l&set DS=%%n)
set "TE=!timer_end:%DE%=%%100)*100+1!" & set "TS=!timer_set:%DS%=%%100)*100+1!"
set/A "T=((((10!TE:%CE%=%%100)*60+1!%%100)-((((10!TS:%CS%=%%100)*60+1!%%100)" & set/A "T=!T:-=8640000-!"
set/A "cc=T%%100+100,T/=100,ss=T%%60+100,T/=60,mm=T%%60+100,hh=T/60+100"
set "value=!hh:~1!%CE%!mm:~1!%CE%!ss:~1!%DE%!cc:~1!" & if "%~2"=="" echo/!value!
endlocal & set "timer_end=%value%" & set "timer_set=" & goto :eof
用法: Timer & echo start_cmds & timeout /t 3 & echo end_cmds & Timer 计时器&计时器“23:23:23,00” 计时器“23:23:23,00”&计时器 计时器“13.23.23,00”&计时器“03:03:03.00” 定时器&定时器“0:00:00.00”no & CMD /v:on /c echo until midnight=!timer_end! 对于执行过程中不太可能但可能发生的时间格式更改,现在可以混合输入
2:函数:与批处理脚本绑定的定时器(示例用法如下):
@echo off
set "TIMER=call :timer" & rem short macro
echo.
echo EXAMPLE:
call :timer
timeout /t 3 >nul & rem Any process here..
call :timer
echo.
echo SHORT MACRO:
%TIMER% & timeout /t 1 & %TIMER%
echo.
echo TEST INPUT:
set "start=22:04:04.58"
set "end=04.22.44,22"
echo %start% ~ start & echo %end% ~ end
call :timer "%start%"
call :timer "%end%"
echo.
%TIMER% & %TIMER% "00:00:00.00" no
echo UNTIL MIDNIGHT: %timer_end%
echo.
pause
exit /b
::要测试它,复制粘贴上面和下面的代码段
rem :AveYo: compact timer function with Regional format, 24-hours and mixed input support
:timer Usage " call :timer [input - optional] [no - optional]" :i Result printed on second call, saved to timer_end
if not defined timer_set (if not "%~1"=="" (call set "timer_set=%~1") else set "timer_set=%TIME: =0%") & goto :eof
(if not "%~1"=="" (call set "timer_end=%~1") else set "timer_end=%TIME: =0%") & setlocal EnableDelayedExpansion
for /f "tokens=1-6 delims=0123456789" %%i in ("%timer_end%%timer_set%") do (set CE=%%i&set DE=%%k&set CS=%%l&set DS=%%n)
set "TE=!timer_end:%DE%=%%100)*100+1!" & set "TS=!timer_set:%DS%=%%100)*100+1!"
set/A "T=((((10!TE:%CE%=%%100)*60+1!%%100)-((((10!TS:%CS%=%%100)*60+1!%%100)" & set/A "T=!T:-=8640000-!"
set/A "cc=T%%100+100,T/=100,ss=T%%60+100,T/=60,mm=T%%60+100,hh=T/60+100"
set "value=!hh:~1!%CE%!mm:~1!%CE%!ss:~1!%DE%!cc:~1!" & if "%~2"=="" echo/!value!
endlocal & set "timer_end=%value%" & set "timer_set=" & goto :eof
CE,DE和CS,DS代表冒号结束,点结束和冒号集合,点集合-用于混合格式支持

下面是我的方法,没有转换和没有ms。它有助于确定编码持续时间(限制在24小时内):
@echo off
:start
REM Start time storage
set ST=%time%
echo Process started at %ST%
echo.
echo.
REM Your commands
REM Your commands
REM Your commands
:end
REM Start Time Definition
for /f "tokens=1-3 delims=:" %%a in ("%ST%") do set /a h1=%%a & set /a m1=%%b & set /a s1=%%c
REM End Time Definition
for /f "tokens=1-3 delims=:" %%a in ("%TIME%") do set /a h2=%%a & set /a m2=%%b & set /a s2=%%c
REM Difference
set /a h3=%h2%-%h1% & set /a m3=%m2%-%m1% & set /a s3=%s2%-%s1%
REM Time Adjustment
if %h3% LSS 0 set /a h3=%h3%+24
if %m3% LSS 0 set /a m3=%m3%+60 & set /a h3=%h3%-1
if %s3% LSS 0 set /a s3=%s3%+60 & set /a m3=%m3%-1
echo Start : %ST%
echo End : %time%
echo.
echo Total : %h3%:%m3%:%s3%
echo.
pause
powershell的另一种方法:
@echo off
for /f %%t in ('powershell "(get-date).tofiletime()"') do set mst=%%t
rem some commands
powershell ((get-date).tofiletime() - %mst%)
这将以毫秒为单位打印执行时间。
如果你安装了CMake,你可以运行下面的命令。
cmake -E time <the_command_to_measure_run_time>
这是一个
后置计时器版本:
使用的例子:
timeout 1 | TimeIt.cmd
Execution took ~969 milliseconds.
复制并粘贴到一些编辑器,如notepad++,并保存为TimeIt.cmd:
:: --- TimeIt.cmd ----
@echo off
setlocal enabledelayedexpansion
call :ShowHelp
:: Set pipeline initialization time
set t1=%time%
:: Wait for stdin
more
:: Set time at which stdin was ready
set t2=!time!
:: Calculate difference
Call :GetMSeconds Tms1 t1
Call :GetMSeconds Tms2 t2
set /a deltaMSecs=%Tms2%-%Tms1%
echo Execution took ~ %deltaMSecs% milliseconds.
endlocal
goto :eof
:GetMSeconds
Call :Parse TimeAsArgs %2
Call :CalcMSeconds %1 %TimeAsArgs%
goto :eof
:CalcMSeconds
set /a %1= (%2 * 3600*1000) + (%3 * 60*1000) + (%4 * 1000) + (%5)
goto :eof
:Parse
:: Mask time like " 0:23:29,12"
set %1=!%2: 0=0!
:: Replace time separators with " "
set %1=!%1::= !
set %1=!%1:.= !
set %1=!%1:,= !
:: Delete leading zero - so it'll not parsed as octal later
set %1=!%1: 0= !
goto :eof
:ShowHelp
echo %~n0 V1.0 [Dez 2015]

echo Usage: ^<Command^> ^| %~nx0

echo Wait for pipe getting ready... :)
echo (Press Ctrl+Z ^<Enter^> to Cancel)
goto :eof

我使用的是Windows XP,由于某些原因,time .exe不适合我。我找到了另一种选择——PTIME。这工作得很好。
http://www.pc-tools.net/win32/ptime/
的例子,
C:\> ptime
ptime 1.0 for Win32, Freeware - http://www.pc-tools.net/
Copyright(C) 2002, Jem Berkes <jberkes@pc-tools.net>
Syntax: ptime command [arguments ...]
ptime will run the specified command and measure the execution time
(run time) in seconds, accurate to 5 millisecond or better. It is an
automatic process timer, or program timer.
C:\> ptime cd

Execution time: 0.015 s
