Creating a repository with git init - Visual Walkthrough

Process Flow - Creating a repository with git init

Open terminal

↓

Navigate to folder

↓

Run 'git init'

↓

Git creates .git folder

↓

Folder becomes a git repository

↓

Ready to track files

This flow shows how running 'git init' in a folder creates a hidden .git directory, turning it into a git repository ready to track changes.

Execution Sample

Git

mkdir myproject
cd myproject
git init

Creates a folder, enters it, and initializes a new git repository inside.

Process Table

Step	Command	Action	Result
1	mkdir myproject	Create folder named 'myproject'	Folder 'myproject' created
2	cd myproject	Change directory to 'myproject'	Current directory is 'myproject'
3	git init	Initialize git repository	Initialized empty Git repository in /path/to/myproject/.git/

💡 After 'git init', the folder is now a git repository with a .git directory

Status Tracker

Variable	Start	After Step 1	After Step 2	After Step 3
Current Directory	User home or wherever	User home or wherever	myproject	myproject
.git folder	Does not exist	Does not exist	Does not exist	Exists inside 'myproject'

Key Moments - 2 Insights

Why do we not see the .git folder after running 'git init'?

The .git folder is hidden by default in most systems. You can see it by running 'ls -a' in the terminal. This is shown in step 3 where git creates the .git directory.

Does 'git init' add any files to the repository automatically?

No, 'git init' only creates the .git folder to track changes. You still need to add files manually. This is why after step 3, the repository is empty but ready.

Visual Quiz - 3 Questions

Look at the execution table, what is the result of running 'git init'?

A Creates a new folder named .git

B Deletes all files in the folder

C Initializes an empty Git repository with a .git folder

D Commits all files automatically

💡 Hint

Check the 'Result' column in step 3 of the execution table

According to the variable tracker, when does the current directory change to 'myproject'?

A After step 2

B After step 1

C After step 3

D It never changes

💡 Hint

Look at the 'Current Directory' row in the variable tracker after each step

If you run 'git init' twice in the same folder, what happens according to the flow?

A It overwrites the existing .git folder

B It does nothing and keeps the existing repository

C It creates two .git folders

D It deletes the folder

💡 Hint

Git init is safe to run multiple times; it reinitializes without overwriting the .git folder or losing data

Concept Snapshot

git init
- Run inside a folder to create a new git repository
- Creates a hidden .git directory to track changes
- Does not add or commit files automatically
- Folder becomes ready for git commands like add, commit
- Use 'ls -a' to see the .git folder

Full Transcript

To create a git repository, first open your terminal and navigate to the folder where you want the repository. Run 'git init' there. This command creates a hidden folder named .git that stores all git data. After this, your folder is a git repository ready to track files. The .git folder is hidden, so use 'ls -a' to see it. Running 'git init' does not add any files automatically; you must add files manually. If you run 'git init' again in the same folder, it safely reinitializes the existing repository without overwriting the .git folder or resetting history.

Practice

1. What does the command git init do in a folder?

easy

A. It creates a new Git repository by adding a hidden .git folder.

B. It deletes all files in the folder.

C. It uploads the folder to a remote server.

D. It merges two branches automatically.

Solution

1. Step 1: Understand the purpose of git init

   The command git init starts a new Git repository in the current folder by creating a hidden .git directory.

2. Step 2: Identify what git init does not do

   It does not delete files, upload data, or merge branches automatically.

3. Final Answer:

   It creates a new Git repository by adding a hidden .git folder. -> Option A

4. Quick Check:

   git init creates .git folder = A [OK]

Hint: Remember: git init creates .git folder to start tracking [OK]

Common Mistakes:

• Thinking git init deletes files
• Confusing git init with git clone
• Assuming git init uploads files

2. Which of the following is the correct syntax to initialize a Git repository in the current directory?

easy

A. git init

B. git start

C. git create

D. git new

Solution

1. Step 1: Recall the Git command to start a repository

   The correct command to initialize a Git repository is git init.

2. Step 2: Verify other options

   Commands like git start, git create, and git new do not exist in Git.

3. Final Answer:

   git init -> Option A

4. Quick Check:

   Initialize repo command = git init = A [OK]

Hint: Use 'git init' exactly to start a repo [OK]

Common Mistakes:

• Typing git start instead of git init
• Using git create or git new which are invalid
• Adding extra words after git init

3. After running git init in an empty folder, what will be the output of ls -a?

medium

A. . .. .gitignore

B. . ..

C. . .. .git .gitignore

D. . .. .git

Solution

1. Step 1: Understand what git init creates

   Running git init creates a hidden .git folder inside the current directory.

2. Step 2: List all files including hidden ones

   The command ls -a shows all files including hidden ones like ., .., and .git. Since the folder is empty except for .git, only these appear.

3. Final Answer:

   . .. .git -> Option D

4. Quick Check:

   git init creates .git folder only = B [OK]

Hint: ls -a shows .git folder after git init [OK]

Common Mistakes:

• Expecting .gitignore to appear automatically
• Not including hidden files in listing
• Confusing .git with other files

4. You ran git init but the .git folder is missing. What is the most likely reason?

medium

A. You ran git init but your folder is already a Git repository.

B. You forgot to install Git on your system.

C. You ran git init inside a folder without write permission.

D. You ran git init with a typo like git initt.

Solution

1. Step 1: Check permissions for creating .git folder

   If the folder does not allow writing, git init cannot create the hidden .git directory.

2. Step 2: Evaluate other options

   If Git was not installed, the command would fail with an error. A typo would cause a command not found error. If the folder was already a Git repo, .git would exist.

3. Final Answer:

   You ran git init inside a folder without write permission. -> Option C

4. Quick Check:

   Missing .git usually means no write permission = D [OK]

Hint: Check folder write permission if .git missing after init [OK]

Common Mistakes:

• Assuming Git is not installed without checking error
• Ignoring typos in command
• Thinking .git disappears if repo exists

5. You want to start tracking an existing project folder with Git. Which sequence of commands correctly initializes the repository and adds all files for the first commit?

hard

A. git init; git commit -m "Initial commit"; git add .

B. git init; git add .; git commit -m "Initial commit"

C. git clone; git add .; git commit -m "Initial commit"

D. git add .; git init; git commit -m "Initial commit"

Solution

1. Step 1: Initialize the Git repository

   Use git init to create the repository in the existing folder.

2. Step 2: Add all files to staging area

   Use git add . to stage all files for commit.

3. Step 3: Commit the staged files

   Use git commit -m "Initial commit" to save the snapshot.

4. Final Answer:

   git init; git add .; git commit -m "Initial commit" -> Option B

5. Quick Check:

   Init, add, then commit = C [OK]

Hint: Always init first, then add files, then commit [OK]

Common Mistakes:

• Running git commit before git add
• Using git clone instead of git init for existing folder
• Adding files before initializing repo
