如何在 DOS 提示符下为脚本计时?
*NIX 等价物是:
$ time myscript
real 0m0.886s
user 0m0.846s
sys 0m0.031s
$
有与此等效的DOS吗?谢谢
您可以使用Windows Server 2003 Resource Kit中的 timeit.exe 。您还可以获得大量其他有用的工具和 Unix 命令端口。
C:\Documents and Settings\Rob>timeit sleep 3

这是一个 DOS 批处理脚本,它将为您计算时间差,而不仅仅是echo %time%
.
只要您的“定时用户部分”运行时间不超过 24 小时,以下代码就可以正常工作。请原谅或给我建议,这是我花了大约一个小时完成的工作。
将“PAUSE”替换为对脚本的调用,以便为您自己的代码计时。
DOS BAT 文件如下:
注意:已编辑以解决前导零是八进制而不是十进制的问题。
注意:经过编辑以处理“午夜”小时环绕运行并在输出中放置前导零。

您可以将其放在批次的开头和结尾:
echo %time%
