如果您使用的是Windows 2003(请注意,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timeit.exe。这是一个例子,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

Version Number:   Windows NT 5.2 (Build 3790)

您可以在Windows 2003 Resource Kit中获取TimeIt。下载它here

我使用名为“GS Timer”的免费软件。

只需制作一个这样的批处理文件:

timer
yourapp.exe
timer /s

如果需要一组时间,只需将timer / s的输出传递到.txt文件中。

我正在使用Windows XP,由于某种原因,timeit.exe对我不起作用。我找到了另一种选择 - PTIME。这非常有效。

http://www.pc-tools.net/win32/ptime/

示例 -

C:\> ptime

ptime 1.0 for Win32, Freeware - http://www.pc-tools.net/
Copyright(C) 2002, Jem Berkes <[email protected]>

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

只要它持续时间不超过24小时......

@echo off

set startcsec=%STARTTIME:~9,2%
set startsecs=%STARTTIME:~6,2%
set startmins=%STARTTIME:~3,2%
set starthour=%STARTTIME:~0,2%

还有TimeMem(2012年3月):

这是一个Windows实用程序,它执行程序并显示其执行时间,内存使用情况和IO统计信息。它的功能类似于Unix时间实用程序。

这是一个单线,避免delayed expansion,这可能会打扰某些命令:

cmd /E /C "prompt $T$$ & echo.%TIME%$ & COMMAND_TO_MEASURE & for %Z in (.) do rem/ "

输出类似于:

14:30:27.58$
...
14:32:43.17$ rem/ 

对于长期测试,用$T替换$D, $T,用%TIME%替换%DATE%, %TIME%以包括日期。

要在批处理文件中使用它,请用%Z替换%%Z


Update

这是一个改进的单线程(也没有delayed expansion):

cmd /E /C "prompt $D, $T$$ & (for %# in (.) do rem/ ) & COMMAND_TO_MEASURE & for %# in (.) do prompt"

输出看起来类似于:

2015/09/01, 14:30:27.58$ rem/ 
...
2015/09/01, 14:32:43.17$ prompt

这种方法不包括在结果中实例化新的cmd的过程,也不包括prompt命令。

这里有一个

用法示例:

Execution took  ~969 milliseconds.

将其复制并粘贴到某些编辑器中,例如Notepad++,并将其另存为TimeIt.cmd:

测量时间的替代方案只是“获取日期”。你没有转发输出等麻烦。

$start = Get-Date
[System.Threading.Thread]::Sleep(1500)
$(Get-Date) - $start

输出:

Days              : 0
Hours             : 0
Minutes           : 0
Seconds           : 1

Ticks             : 15060003

如果有其他人来这里寻找这个问题的答案,那么有一个名为GetProcessTimes()的Windows API函数。编写一个可以启动命令,进行此调用并返回处理时间的小C程序看起来不是太多工作。

这是我的方法,没有转换,没有ms。确定编码持续时间(限制为24小时)非常有用:

set ST=%time%
echo Process started at %ST%

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

或者,Windows PowerShell具有类似于Bash的“time”命令的内置命令。它被称为“测量 - 命令”。您必须确保在运行它的计算机上安装PowerShell。

示例输入:

Measure-Command {echo hi}

示例输出:

Days              : 0
Hours             : 0
Minutes           : 0
Seconds           : 0
Milliseconds      : 0

根据您使用的Windows版本,只需运行bash即可进入Bash模式。这将允许您使用PowerShell上不可用的一组命令(如time命令)。现在,执行命令的时机就像执行一样简单:

# The clause <your-command> (without the angle brackets) denotes the command you want to run.
$ time <your-command>

注意:您可以通过在Bash模式下运行exit轻松退出Bash模式并返回主流shell。

在尝试了其他方法(如Measure-Command)之后,这对我来说非常适合(Windows 10),这些方法有时会产生不需要的统计数据。希望这也适合你。

以下脚本仅使用“cmd.exe”,并输出从创建管道到脚本退出之前的进程的毫秒数。即,键入您的命令,并将其传递给脚本。示例:“timeout 3 | runtime.cmd”应该产生类似“2990”的内容。如果你需要运行时输出和stdin输出,在管道之前重定向stdin - ex:“dir / s 1> temp.txt | runtime.cmd”会将“dir”命令的输出转储到“temp.txt”并将运行时打印到控制台。

  2. 粘贴下面的代码,将YourApp.exe替换为您的程序,然后保存。 @echo off date /t time /t YourApp.exe date /t time /t
  3. 在命令行中键入mytimer.bat,然后按Enter键。

我的代码以毫秒为单位为您提供运行时间,最多24小时,对区域设置不敏感,如果代码在午夜运行,则会出现负值。它使用延迟扩展,并应保存在cmd / bat文件中。

在您的代码之前:

SETLOCAL EnableDelayedExpansion

for /f "tokens=2 delims==" %%I in ('wmic os get localdatetime /format:list') do set t=%%I
set /a t1 = %t:~8,1%*36000 + %t:~9,1%*3600 + %t:~10,1%*600 + %t:~11,1%*60 + %t:~12,1%*10 + %t:~13,1% && set t1=!t1!%t:~15,3%

在您的代码之后:

for /f "tokens=2 delims==" %%I in ('wmic os get localdatetime /format:list') do set t=%%I
set /a t2 = %t:~8,1%*36000 + %t:~9,1%*3600 + %t:~10,1%*600 + %t:~11,1%*60 + %t:~12,1%*10 + %t:~13,1% && set t2=!t2!%t:~15,3%
set /a t2-=t1 && if !t2! lss 0 set /a t2+=24*3600000

如果您想以HH:mm:ss.000格式运行时间,请添加:

set /a "h=t2/3600000,t2%%=3600000,m=t2/60000,t2%%=60000" && set t2=00000!t2!&& set t2=!t2:~-5!
if %h% leq 9 (set h=0%h%) && if %m% leq 9 (set m=0%m%)
set t2=%h%:%m%:%t2:~0,2%.%t2:~2,3%

ENDLOCAL

变量t2保持你的运行时间,你可以echo %t2%显示它。

以下脚本模拟* nix纪元时间,但它是本地和区域的。它应该处理包括闰年在内的压延边缘情况。如果Cygwin可用,则可以通过指定Cygwin选项来比较纪元值。

让Perl安装可用的雇佣解决方案,运行:

C:\BATCH>time.pl "echo Fine result"
0.01063
Fine result

STDERR在测量秒之前出现

#!/usr/bin/perl -w

use Time::HiRes qw();
my $T0 = [ Time::HiRes::gettimeofday ];

my $stdout = `@ARGV`;

my $time_elapsed = Time::HiRes::tv_interval( $T0 );

print $time_elapsed, "\n";
print $stdout;

如果你想

  1. 以(hh:mm:ss.ff格式)测量执行时间到百分之一秒
  2. 无需下载和安装资源包
  3. 看起来像一个巨大的DOS书呆子(谁没有)

尝试将以下脚本复制到新的批处理文件中(例如timecmd.bat):

@echo off
@setlocal

set start=%time%

:: Runs your command
cmd /c %*

set end=%time%
set options="tokens=1-4 delims=:.,"
for /f %options% %%a in ("%start%") do set start_h=%%a&set /a start_m=100%%b %% 100&set /a start_s=100%%c %% 100&set /a start_ms=100%%d %% 100
for /f %options% %%a in ("%end%") do set end_h=%%a&set /a end_m=100%%b %% 100&set /a end_s=100%%c %% 100&set /a end_ms=100%%d %% 100

set /a hours=%end_h%-%start_h%
set /a mins=%end_m%-%start_m%
set /a secs=%end_s%-%start_s%
set /a ms=%end_ms%-%start_ms%
if %ms% lss 0 set /a secs = %secs% - 1 & set /a ms = 100%ms%
if %secs% lss 0 set /a mins = %mins% - 1 & set /a secs = 60%secs%
if %mins% lss 0 set /a hours = %hours% - 1 & set /a mins = 60%mins%
if %hours% lss 0 set /a hours = 24%hours%
if 1%ms% lss 100 set ms=0%ms%

:: Mission accomplished
set /a totalsecs = %hours%*3600 + %mins%*60 + %secs%
echo command took %hours%:%mins%:%secs%.%ms% (%totalsecs%.%ms%s total)

用法

如果将timecmd.bat放在路径中的目录中,可以从以下任何位置调用它:

timecmd [your command]

EG

C:\>timecmd pause
Press any key to continue . . .
command took 0:0:1.18

如果要进行输出重定向,可以像这样引用命令:

timecmd "dir c:\windows /s > nul"

这应该处理从午前到午夜之间运行的命令,但如果命令运行24小时或更长时间,输出将是错误的。

呵呵,最简单的解决方案可能就是:

echo %time%
YourApp.exe
echo %time%

这适用于每个开箱即用的Windows。


如果应用程序使用控制台输出,则可以方便地将开始时间存储在临时变量中:

set startTime=%time%
YourApp.exe
echo Start Time: %startTime%
echo Finish Time: %time%

关于使用来自the answer from Casey.KMeasure-CommandPowerShell的一点扩展:

  1. 您可以从标准命令提示符调用PowerShell,如下所示: powershell -Command "Measure-Command {echo hi}"
  2. 这将使用标准输出,但您可以通过从PowerShell添加这样的| Out-Default来防止这种情况: Measure-Command {echo hi | Out-Default} 或者从命令提示符: powershell -Command "Measure-Command {echo hi | Out-Default}"

当然,你可以自由地将它包装在脚本文件*.ps1*.bat中。

我在Windows Server 2008 R2中使用的单行程序是:

cmd /v:on /c "echo !TIME! & *mycommand* & echo !TIME!"

只要mycommand不需要引号(使用cmd的引用处理)。 /v:on允许独立评估两个不同的TIME值,而不是在执行命令时评估一次。

如果打开命令窗口并手动调用命令,则可以在每个提示上显示时间戳,例如:

prompt $d $t $_$P$G

它给你的东西:

23.03.2009 15:45:50,77

C:\>

如果您有一个执行命令的小批处理脚本,则在每个命令之前都有一个空行,例如

(空行)

myCommand.exe

(下一个空行)

myCommand2.exe

您可以通过提示中的时间信息计算每个命令的执行时间。最好的方法是将输出传递给文本文件以进行进一步分析:

MyBatchFile.bat > output.txt

由于其他人建议安装诸如免费软件和PowerShell之类的东西,你也可以安装Cygwin,它可以让你访问许多基本的Unix命令,如time

abe@abe-PC:~$ time sleep 5

real    0m5.012s
user    0m0.000s
sys 0m0.000s

不确定Cygwin增加了多少开销。

不像Unix上的某些功能那么优雅,但创建一个cmd文件,如下所示:

@echo off
time < nul
yourexecutable.exe > c:\temp\output.txt
time < nul
rem on newer windows system you can try time /T

这将显示开始和停止时间,如下所示:

The current time is: 10:31:57.92
Enter the new time:
The current time is: 10:32:05.94
Enter the new time:
