How to write date and time in BASH script?

Question

linux

I want to write a small bash script that will send my files to git.
I can’t catch up, how can I write the date and time instead of a comment?

git commit -a -m "comment"

Answer 1

git commit -a -m "comment `date +"%Y%m%d %H:%M"`"
or
git commit -a -m "comment $(date +"%Y%m%d %H:% M")"
select the desired date format from "man date"
