Git from the Ground Up

" summary

Runs real git commands and inspects .git to reveal what actually happens: a git clone fetches 49,241 objects which git compresses into a 17 MB pack with an .idx table; git cat-file shows that branches are SHA‑1 pointers and each commit creates commit/tree/blob objects; git push repacks loose objects into packfiles; merge produces a commit with two parents while rebase rewrites commits to create a linear history. Practical demonstrations use git clone, git add/commit, git push, git cat-file, git unpack-objects.
