Creating branches with git branch - Visual Walkthrough

Process Flow - Creating branches with git branch

Start in main branch

↓

Run 'git branch <new-branch>'

↓

New branch created locally

↓

Check branches with 'git branch'

↓

New branch listed, current branch unchanged

This flow shows how creating a new branch with 'git branch' adds it locally without switching to it.

Execution Sample

Git

git branch feature1
git branch

Creates a new branch named 'feature1' and lists all branches.

Process Table

Step	Command	Action	Result	Current Branch
1	git branch feature1	Create new branch 'feature1'	Branch 'feature1' created locally	main
2	git branch	List all branches	* main feature1	main

💡 No branch switch occurs; current branch remains 'main'.

Status Tracker

Variable	Start	After Step 1	After Step 2
Branches	main	main, feature1	main, feature1
Current Branch	main	main	main

Key Moments - 2 Insights

Does 'git branch <name>' switch to the new branch?

No, it only creates the branch locally. The current branch stays the same as shown in the execution_table step 1 and 2.

How can I see the new branch after creating it?

Use 'git branch' to list all branches. The new branch will appear but is not checked out yet, as shown in execution_table step 2.

Visual Quiz - 3 Questions

Look at the execution table, what is the current branch after running 'git branch feature1'?

A main

B feature1

C No branch

D Detached HEAD

💡 Hint

Check the 'Current Branch' column in execution_table row 1.

At which step does the new branch 'feature1' appear in the branch list?

A Step 1

B Before Step 1

C Step 2

D It never appears

💡 Hint

Look at the 'Result' column in execution_table for branch listing.

If you want to switch to the new branch immediately after creating it, what should you do?

A Run 'git branch feature1' again

B Run 'git checkout feature1'

C Run 'git branch -d feature1'

D Run 'git merge feature1'

💡 Hint

Creating a branch does not switch to it; checkout is needed to switch branches.

Concept Snapshot

git branch <name> creates a new branch locally without switching.
Use 'git branch' to list all branches.
Current branch remains unchanged after creation.
To switch, use 'git checkout <name>' or 'git switch <name>'.

Full Transcript

Creating a branch with 'git branch <name>' adds a new branch locally but does not change your current branch. After running the command, you can list all branches with 'git branch' and see the new branch listed. However, you remain on the original branch until you explicitly switch using 'git checkout' or 'git switch'. This helps you prepare branches without moving away from your current work.

Practice

1. What does the command git branch new-feature do?

easy

A. Creates a new branch named 'new-feature' without switching to it

B. Creates and switches to a new branch named 'new-feature'

C. Deletes the branch named 'new-feature'

D. Merges 'new-feature' branch into the current branch

Solution

1. Step 1: Understand the git branch command

   The command git branch <branch-name> creates a new branch but does not switch to it.

2. Step 2: Analyze the given command

   git branch new-feature creates a branch called 'new-feature' but stays on the current branch.

3. Final Answer:

   Creates a new branch named 'new-feature' without switching to it -> Option A

4. Quick Check:

   git branch creates branch only [OK]

Hint: git branch creates branch but does not switch [OK]

Common Mistakes:

• Thinking it switches to the new branch automatically
• Confusing branch creation with branch deletion
• Assuming it merges branches

2. Which of the following is the correct syntax to create a branch named feature1 using git?

easy

A. git branch -c feature1

B. git create branch feature1

C. git branch feature1

D. git new branch feature1

Solution

1. Step 1: Recall the correct git branch creation syntax

   The correct syntax to create a branch is git branch <branch-name>.

2. Step 2: Check each option

   git branch feature1 matches the correct syntax exactly: git branch feature1. Others are invalid commands.

3. Final Answer:

   git branch feature1 -> Option C

4. Quick Check:

   Correct syntax = git branch <name> [OK]

Hint: Use 'git branch branch-name' to create branch [OK]

Common Mistakes:

• Using incorrect flags like -c
• Adding extra words like 'create' or 'new'
• Confusing branch creation with checkout

3. Given the commands:
git branch test-branch
git branch
What will be the output of git branch?

medium

A. main\ntest-branch

B. main\n* test-branch

C. * test-branch

D. * main\n test-branch

Solution

1. Step 1: Understand branch creation and listing

   git branch test-branch creates a new branch but does not switch to it. The current branch remains the same.

2. Step 2: Check the output of git branch

   The output lists all branches. The current branch is marked with an asterisk (*). Since we did not switch, the current branch is still 'main'.

3. Final Answer:

   * main\n test-branch -> Option D

4. Quick Check:

   Current branch marked *; new branch listed but not active [OK]

Hint: New branch created but current branch stays same [OK]

Common Mistakes:

• Assuming new branch is active immediately
• Missing the asterisk for current branch
• Listing branches without indentation or markers

4. You run git branch new-feature but then try git checkout new-feature and get an error. What is the most likely cause?

medium

A. You misspelled the branch name when checking out

B. You need to use git switch instead of git checkout

C. The branch was not created because of a syntax error

D. You are not in a git repository

Solution

1. Step 1: Understand the error context

   If git checkout new-feature fails after creating the branch, the branch might not exist under that exact name.

2. Step 2: Check common causes

   Most often, the branch name is misspelled or has a typo when checking out. Other options are less likely if branch creation succeeded.

3. Final Answer:

   You misspelled the branch name when checking out -> Option A

4. Quick Check:

   Branch name typo causes checkout error [OK]

Hint: Check branch name spelling before checkout [OK]

Common Mistakes:

• Assuming checkout command is deprecated
• Ignoring typos in branch names
• Not verifying current directory is a git repo

5. You want to create a new branch featureX and immediately start working on it. Which sequence of commands correctly achieves this?

hard

A. git checkout -b featureX

B. All of the above

C. git branch featureX\ngit switch featureX

D. git branch featureX\ngit checkout featureX

Solution

1. Step 1: Understand branch creation and switching

   Creating a branch and switching to it can be done in multiple ways: using separate commands or combined commands.

2. Step 2: Analyze each option

   git branch featureX\ngit checkout featureX creates the branch then switches using checkout. git checkout -b featureX creates and switches in one step. git branch featureX\ngit switch featureX creates then switches using the newer 'git switch' command. All are valid.

3. Final Answer:

   All of the above -> Option B

4. Quick Check:

   Multiple valid ways to create and switch branch [OK]

Hint: Use 'git checkout -b' or 'git switch -c' to create and switch [OK]

Common Mistakes:

• Thinking only one command works
• Confusing 'git switch' with 'git checkout'
• Not knowing combined commands exist
