Teil II. Grundlagen von Git
Die folgenden Kapitel zeigen, wie Git Dateien verwaltet, erklären die Bedeutung des Index und wie er mit diesem Prozess zusammenhängt, und werfen einen detaillierten Blick auf das Commit-Objekt und die wichtige Rolle, die Zweige in einem Git-Repository spielen.
Bevor wir fortfahren, möchten wir erklären, warum wir uns entschieden haben, diese Themen in dieser Reihenfolge zu behandeln.
In "Git Internals: Konzepte bei der Arbeit" haben wir die verfügbaren Objekte innerhalb des Git-Objektspeichers auseinandergenommen. Schauen wir uns nun an, wie die Objekte erstellt werden und wann sie miteinander verknüpft werden.

$mkdir myrepo && cd myrepo$git statusfatal: not a git repository (or any of the parent directories): .git $tree .git.git [error opening dir] 0 directories, 0 files
Da es sich nicht um ein Git-Repository handelt, gibt es kein .git-Verzeichnis. Als Nächstes werden wir ein leeres Git-Repository initialisieren und den Inhalt des Verzeichnisses erneut überprüfen:
$git init -b mainInitialized empty Git repository in /myrepo/.git/ $tree .git.git ├── HEAD ├── config ├── description ├── hooks │ ├── applypatch-msg.sample │ ├── commit-msg.sample │ ├── fsmonitor-watchman.sample │ ├── post-update.sample │ ├── pre-applypatch.sample │ ├── pre-commit.sample │ ├── pre-merge-commit.sample │ ├── pre-push.sample │ ├── pre-rebase.sample │ ├── pre-receive.sample ...
