英文:
Print date 5 days before in particular format
问题
I'm trying to get a particular format of a date that was 5 days ago. I'm running bash on MacOS.
Currently I have:
date -v -5d
Wed 1 Jan 2020 09:32:07 EST
But the format I'm looking for is:
2020-01-01
Looking at some solutions, I have something like:
DATE=$(date +"%Y%m%d")
date -j -f %Y%m%d -v-5d "${DATE}" +%Y-%m-%d
2020-01-01
Would this be the most optimal way to do this?

与date -v -5d一样，无需提供明确的输入日期，以下命令也可以使用：
date -v -5d +%F # %F是%Y-%m-%d的缩写
您只需添加所需的输出格式。
英文:
Just like date -v -5d works without providing an explicit input date, so will
date -v -5d +%F # %F is short for %Y-%m-%d
You just need to add the desired output format.
