The following command generates the date for the next day:
date -d "20150615 12:00 +1 day" +%Y%m%d 20150616
I would like to specify my own INPUT date format, such as:
But the date command does not like this format and complains about invalid date:
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.
