Yes you right I had think it would be one line :). No worried I search not 
efficient, it will be only a help in the daily hobby project. Every time 
manuell run grep make sick on a computer which are build to make our life
easier :)

Yes this files are markdown text files with a header and the content text. 

title: "Title"
date: 2019-10-15
tags: "Gesellschaft"
shorttext: ""
draft: false
lang: de
cover: "society"

So date is in every file and ever in same format because the date formatting
make hugo when build the pages.

This work it give files and content like: 

$ cat de.list 
content/de/blog/die-grünen-heuchler.md:date: 2019-10-16
content/de/blog/die-killer.md:date: 2019-10-17

But this will not work. There is no output at end with a bit 
playing it run endless or there come Syntax Errors. But an Idea 
is born. 

Nice Day & Thank you
