计算时间(增加分钟)bash [英] Calculating time (adding minutes) bash

问题描述

我陷入了剧本的一部分.我有时间:例如"16:00"，持续时间以分钟为单位:410.

I got stuck in part of the script. I have time: for example "16:00" and duration in minutes like: 410.

是否有任何简单的方法可以将这两个值相加?我已经尝试了很多与date -d的组合，但无法解决.

Is there any easy way to add those two values? I've tried a lot of combinations with date -d, but can't solve it.

推荐答案

尝试一下(Kysu版本):

Try this (Kysu's version):

date -d "16:00 410 minutes" +'%H:%M'

或者这个:

date -d "16:00 today + 410 minutes" +'%H:%M'

但请勿使用此功能:

date -d "16:00 + 410 minutes" +'%H:%M'   # BAD!

如果省略单词today但保留+，则会发生奇怪的事情. (我认为+ 410被解析为时区修饰符，然后minutes被解释为加一分钟".)

Strange things happen if you omit the word today but keep the +. (I think the + 410 is being parsed as a timezone modifier, and then the minutes is interpreted as "add one minute".)
