Linus Torvalds

Creator of git & linux kernel maintainer

You can disagree with me as much as you want, but during this talk, by definition anybody who disagrees is stupid and ugly. So keep that in mind. When I'm done speaking, you can go on with their lives.

WTH is git?

Git is distributed, file-based version control system

---

See what's under the hood

---

Unified experience

---

Let's dive in!

---

Initializing the repo

git init

---

Look into the .git dir

---

Snapshots not diffs

---

Basic objects

• blob
• tree
• commit

---

Branches

Branch as a pointer

---

Working directory Staging area Repository

---

Checking what we have

Checking whether we have unstaged files

git status

Browsing previous commits

git log

---

Adding files to the staging area

git add some_file.py another_file.java

You can use dot to add all modified files (regex)

git add .

---

Moving, renaming, deleting files

git mv some_file.py

git rm some_file.py

How it works under the hood?

rm some_file.py

git add some_file.py

---

Commit & push

git commit -m "My commit message"

git push

When pushing for the first time

git push -u origin my_branch

• where my_branch is usually master or main.
