I don’t know how you handle it, but if I have a directory of numbered files, I would like them all to have equal length, for that “ls” and autocomplete will show them in appropriate order, but yet I don’t want all the files to consist of let’s say a dozen chars, when five ones would be enough.
So, some days ago I downloaded a couple of files (2469) that were numerated, but without leading “0”, and as 2000 files is quite a lot of work to rename by hand, I wrote this small little Python3-Script that should do the trick for you:

As soon as I get able to do it, I will create a "blog_snippets"-Repo on our Github-Page and push it there, including all changes me or some other f3l-member will do.
