Time 如何在DOS中为脚本计时？

如何在DOS提示符下计时脚本

*尼克斯等效值为：

$ time myscript

real 0m0.886s
user 0m0.846s
sys 0m0.031s

$

---

有与此等效的DOS吗？谢谢

您可以将其放在批次的开始和结束处：

echo %time%

---

这是一个DOS批处理脚本，它将为您计算时差，而不仅仅是执行

echo%time%

只要“定时用户部分”的运行时间不超过24小时，以下代码就可以正常工作。请原谅我，或者给我一些建议，这是我花了大约一个小时才完成的一项正在进行的工作

将“暂停”替换为调用脚本来计时自己的代码

DOS BAT文件如下：

注意：已编辑以修复前导零为八进制而非十进制的问题

注意：已编辑以处理“午夜”小时的换行，并在输出中放置前导零

如果您不介意使用第三方EXE提供帮助，那么from非常有用

setlocal ENABLEEXTENSIONS

@rem Do your work Here
call userscript.bat %*

timer %start_time% "Total time"
endlocal

你真的是在谈论DOS，还是windows的命令外壳？这种方法的可能重复对我来说是最简单的，但有一点麻烦。我正在为位于c:\windows\system32中的dos批处理文件计时。当我尝试计时时，我必须输入.bat的完全限定路径，即使它在我的系统路径中。警告：不要直接在命令上使用它（
echo%time%&myprog&echo%time%
），因为这两个命令的扩展都是在命令执行之前完成的。
