How to rename these files in bulk via shell and regular expressions?

Question

I trying to modify a lot of files with names like 2020-06-28 16.19.50.md, removing the spaces and symbols, retain only the first 12 digits as 202006281619.md.

Hopefully this can be done with a shell script through Regular Expressions. Selecting these files in the macOS Finder, right-click and run the Service script to complete the changes.

Try something like this to remove spaces, dots and dashes `s/[ .-]//g` — Mark Setchell, Jun 28 '20 at 09:24
@MarkSetchell Thank you, and then how do I remove the last two digits (remove 5 and 0 in this example, there's no underscore here)? — Joey, Jun 28 '20 at 09:47

I don't use Regular Expressions. But this can remove spaces of current directory's file names.

for f in *; do mv "$f" "$(echo $f | sed 's/ //'g)" ; done
