What are valid input DATE formats for the (Linux) date command?
提问by Xofo
The following command generates the date for the next day:
以下命令生成第二天的日期:
date -d "20150615 12:00 +1 day" +%Y%m%d
20150616
I would like to specify my own INPUT date format, such as:
我想指定我自己的 INPUT 日期格式,例如:
2015_06_15
2015_06_15
But the date command does not like this format and complains about invalid date:
但是 date 命令不喜欢这种格式并抱怨无效日期:
date: invalid date '2015_06_15 12:00 +1 day'
Is it possible to use such a date format? And if so how could I do this.
是否可以使用这样的日期格式?如果是这样,我怎么能做到这一点。
