Pretty neat! Could probably make some simple shell scripts from the examples shown, not-git-status, not-git-commit, etc

You can simulate git via:

mkdir v2 ; cp -rp v1 v2

After understanding the content of this blog post, I'd recommend reading the "Internals" chapter of the Git documentation (most of us don't use many of the available "plumbing" commands) - https://git-scm.com/book/en/v2/Git-Internals-Plumbing-and-Po....

Title is horribly incorrect.

Simulating git would be more appropriate.

I expected this to be a look at other version control systems around today. It's yet another 'let's recreate git from scratch, kinda' post.

I think a closer example at the filesystem level would be

  rsnapshot alpha

rsnapshot [1] uses hard links when it can to create a delta of changed files. Reverting can be done with rsync or cherry picking files. git blame would have to be done via something like auditd and syslog and nowhere near as easy as using git. I use rsnapshot to back up my git repos in the event they get corrupted.
