Calculating time (adding minutes) bash
提问by Kysu
I got stuck in part of the script. I have time: for example "16:00" and duration in minutes like: 410.
我陷入了脚本的一部分。我有时间:例如“16:00”和持续时间(以分钟为单位):410。
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.
有什么简单的方法可以添加这两个值吗?我尝试了很多与 的组合date -d
,但无法解决。

Try this (Kysu's version):
试试这个(Kysu 的版本):
date -d "16:00 410 minutes" +'%H:%M'
or this:
或这个:
date -d "16:00 today + 410 minutes" +'%H:%M'
But do notuse this:
但不要使用这个:
date -d "16:00 + 410 minutes" +'%H:%M' # BAD!
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".)
如果你省略这个词today
但保留+
. (我认为+ 410
被解析为时区修饰符,然后minutes
被解释为“增加一分钟”。)
