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?
当前回答
如果您使用的是Windows 2003(注意不支持Windows server 2008及更高版本),您可以使用Windows server 2003资源工具包,其中包含显示详细执行统计信息的time .exe。这里有一个例子,计时命令“timeit -?”:
C:\>timeit timeit -?
Invalid switch -?
Usage: TIMEIT [-f filename] [-a] [-c] [-i] [-d] [-s] [-t] [-k keyname | -r keyname] [-m mask] [commandline...]
where: -f specifies the name of the database file where TIMEIT
keeps a history of previous timings. Default is .\timeit.dat
-k specifies the keyname to use for this timing run
-r specifies the keyname to remove from the database. If
keyname is followed by a comma and a number then it will
remove the slowest (positive number) or fastest (negative)
times for that keyname.
-a specifies that timeit should display average of all timings
for the specified key.
-i specifies to ignore non-zero return codes from program
-d specifies to show detail for average
-s specifies to suppress system wide counters
-t specifies to tabular output
-c specifies to force a resort of the data base
-m specifies the processor affinity mask

您可以在Windows 2003资源工具包中获得TimeIt。它不能从微软下载中心直接下载,但仍然可以从archive.org - Windows Server 2003资源工具包工具中获得。

因为其他人建议安装像免费软件和PowerShell这样的东西,你也可以安装Cygwin,它可以让你访问许多基本的Unix命令,比如time:
abe@abe-PC:~$ time sleep 5
real 0m5.012s
user 0m0.000s
sys 0m0.000s
不知道Cygwin增加了多少开销。

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:

The following script uses only "cmd.exe" and outputs the number of milliseconds from the time a pipeline is created to the time that the process preceding the script exits. i.e., Type your command, and pipe the to the script. Example: "timeout 3 | runtime.cmd" should yield something like "2990." If you need both the runtime output and the stdin output, redirect stdin before the pipe - ex: "dir /s 1>temp.txt | runtime.cmd" would dump the output of the "dir" command to "temp.txt" and would print the runtime to the console.

“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
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。
