如何记录unix命令所需的时间？ [英] How to log the time taken for a unix command?

问题描述

我知道我的脚本将需要超过10小时才能运行。有没有办法记录它的开始时间和结束的时间？

I know my script is going to take more than 10 hours to run. Is there a way to log the time it starts and the time it ends ?

时间命令只是时间过程还是我得到我计时的过程的输出？

Does the time command just time the process or do I get the output of the process that I'm timing ?

推荐答案

使用 time 命令（详情）：

time your_prog

如果时间不适合你，我会尝试记录 date （详细信息）在程序执行之前和之后，例如

If time does not fit for you, I would try to log the output of date (details) before and after the execution of your program, e.g.

date > log.txt; your_prog; date >> log.txt

最后，您还可以添加一些格式（注意：灵感来自Raze2dust的回答）：

Finally, you can also add some formatting (NOTE: inspired by Raze2dust's answer):

echo "started at: $(date)" > log.txt; your_prog; echo "ended at: $(date)" >> log.txt
