Simple filename timestamp

When writing Jekyll posts or creating log files with dates on them, I usually
struggle with finding a direct way of accomplishing that. There’s a simple
solution: date -I
.
Using this built-in GNU/Linux tool allows you to touch $(date -I).md
to readily
create a 2020-08-12.md
file.
I always had to read man date
or search the web over and over, and after doing
this repeatedly it became clear that both date -I
and date -Is
(s
here
stands for seconds) are the thing that I’m looking for 95% of the time:
Both date formats are hierarchical, having the bigger time intervals to the left. This means that you can easily sort them (and even tab-complete them) with no extra effort or tool required.
