How do I measure execution time of a command on the Windows command line?
在Windows命令行上是否有内置的方法来度量命令的执行时间?
或者,WindowsPowerShell有一个类似于bash的"time"命令的内置命令。它被称为"measure命令"。您必须确保在运行它的计算机上安装了PowerShell。
实例输入:
1 | Measure-Command {echo hi} |
实例输出:
1 2 3 4 5 6 7 8 9 10 11 | Days : 0 Hours : 0 Minutes : 0 Seconds : 0 Milliseconds : 0 Ticks : 1318 TotalDays : 1.52546296296296E-09 TotalHours : 3.66111111111111E-08 TotalMinutes : 2.19666666666667E-06 TotalSeconds : 0.0001318 TotalMilliseconds : 0.1318 |
如果你想要
尝试将以下脚本复制到新的批处理文件(例如timeCmd.bat)中:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 | @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,则可以从以下任何位置调用它:
1 | timecmd [your command] |
例如。
1 2 3 | C:\>timecmd pause Press any key to continue . . . command took 0:0:1.18 |
如果要执行输出重定向,可以这样引用命令:
1 | timecmd"dir c:\windows /s > nul" |
这应该处理从午夜前后运行的命令,但如果命令运行24小时或更长时间,则输出将出错。
呵呵,最简单的解决办法可能是:
1 2 3 | echo %time% YourApp.exe echo %time% |
它适用于所有开箱即用的窗口。
对于使用控制台输出的应用程序,可以方便地将启动时间存储在临时变量中:
1 2 3 4 | set startTime=%time% YourApp.exe echo Start Time: %startTime% echo Finish Time: %time% |
如果您使用的是Windows 2003(请注意,不支持Windows Server 2008及更高版本),则可以使用Windows Server 2003资源工具包,其中包含显示详细执行状态的timeit.exe。下面是一个例子,计时命令"timeit-?":
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 | 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) Exit Time: 7:38 am, Wednesday, April 15 2009 Elapsed Time: 0:00:00.000 Process Time: 0:00:00.015 System Calls: 731 Context Switches: 299 Page Faults: 515 Bytes Read: 0 Bytes Written: 0 Bytes Other: 298 |
您可以在Windows 2003资源工具包中获取Timeit。下载它在这里。
只是对casey.k关于使用PowerShell中的
您可以从标准命令提示符调用PowerShell,如下所示:
1 | powershell -Command"Measure-Command {echo hi}" |
这将占用标准输出,但您可以通过从PowerShell中添加这样的EDOCX1[3]来防止这种情况:
1 | Measure-Command {echo hi | Out-Default} |
或从命令提示:
1 | powershell -Command"Measure-Command {echo hi | Out-Default}" |
当然,您可以将其包装在脚本文件
我在Windows Server 2008 R2中使用的一行程序是:
1 | cmd /v:on /c"echo !TIME! & *mycommand* & echo !TIME!" |
只要mycommand不需要引号(哪个螺钉带有cmd的引号处理)。
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
1 | prompt $d $t $_$P$G |
它给你的感觉是:
23.03.2009 15:45:50,77
C:\>
如果您有一个执行命令的小批处理脚本,那么在每个命令之前都有一个空行,例如。
(empty line)
myCommand.exe
(next empty line)
myCommand2.exe
您可以根据提示中的时间信息计算每个命令的执行时间。最好的方法可能是通过管道将输出传输到文本文件进行进一步分析:
1 | MyBatchFile.bat > output.txt |
由于其他人建议安装免费软件和PowerShell,您也可以安装cygwin,这样您就可以访问许多基本的UNIX命令,如time:
1 2 3 4 5 | abe@abe-PC:~$ time sleep 5 real 0m5.012s user 0m0.000s sys 0m0.000s |
不知道Cygwin增加了多少开销。
不像Unix上的某些功能那么优雅,但是创建一个如下所示的cmd文件:
1 2 3 4 5 | @echo off time < nul yourexecutable.exe > c:\temp\output.txt time < nul rem on newer windows system you can try time /T |
它将显示开始和停止时间,如下所示:
1 2 3 4 | The current time is: 10:31:57.92 Enter the new time: The current time is: 10:32:05.94 Enter the new time: |
我用的是名为"GS定时器"的免费软件。
只需制作这样的批处理文件:
1 2 3 | timer yourapp.exe timer /s |
如果您需要一组时间,只需将timer/s的输出导入一个.txt文件。

我使用的是Windows XP,出于某种原因,Timeit.exe不适合我。我找到了另一个选择——提姆。这很管用。

在卢克·桑普森的评论中,这个版本是八进制安全的,尽管任务应该在24小时内完成。
我的代码以毫秒为单位提供运行时间,最长24小时,它不区分区域设置,并且如果代码运行到午夜,则说明负值。它使用延迟的扩展,应该保存在一个cmd/bat文件中。

以下是我的方法,没有转换,也没有毫秒。确定编码持续时间(仅限于24小时)很有用:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 | @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 |
使用Sub返回以百分之一秒为单位的时间

"精益平均"计时器,支持区域格式、24小时和混合输入调整aacini的替换方法体,不使用if,只使用一个for(我的区域修复)
1:文件timer.bat放在%path%或当前目录的某个位置

用途:计时器&echo start_-comms&timeout/t 3&echo end_-comms&timer计时器和计时器"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"计时器&timer"0:00:00.00"否&cmd/v:on/c echo until middle=!TimeReEnter!对于那些不太可能但在执行过程中可能发生的时间格式更改,现在可以混合输入。
2:函数:与批处理脚本捆绑在一起的计时器(示例用法如下):
