Creating and switching in one step in Git - Try It Yourself

Creating and switching branches in one step with Git

📖 Scenario: You are working on a project using Git for version control. You need to create a new branch and switch to it quickly to start working on a new feature.

🎯 Goal: Learn how to create a new Git branch and switch to it in a single command.

📋 What You'll Learn

Create a new branch named feature-xyz

Switch to the new branch immediately after creating it

Verify the current branch is feature-xyz

💡 Why This Matters

🌍 Real World

Creating and switching branches quickly helps developers work on new features or fixes without disturbing the main code.

💼 Career

Branch management is a fundamental skill for software developers, DevOps engineers, and anyone working with version control systems like Git.

1

Initialize a Git repository

Run the command git init to create a new Git repository in your current folder.

Git

# Run the command to initialize a Git repository
# Your code here

Hint

Use git init to start a new Git repository.

2

Create a new branch variable

Create a variable called branch_name and set it to the string feature-xyz.

Git

git init
# Create a variable called branch_name with value 'feature-xyz'
# Your code here

Hint

Use branch_name='feature-xyz' to store the branch name.

3

Create and switch to the new branch in one step

Use the command git checkout -b $branch_name to create and switch to the branch named feature-xyz. Use the variable branch_name in the command.

Git

git init
branch_name='feature-xyz'
# Run the command to create and switch to the branch using branch_name
# Your code here

Hint

Use git checkout -b $branch_name to create and switch branches in one step.

4

Verify the current branch

Run the command git branch --show-current to display the current branch name and confirm it is feature-xyz.

Git

git init
branch_name='feature-xyz'
git checkout -b $branch_name
# Run the command to show the current branch
# Your code here

Hint

Use git branch --show-current to see the active branch.

Practice

1. What does the command git switch -c feature do?

easy

A. Lists all branches including 'feature'

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

C. Switches to the existing branch named 'feature' without creating it

D. Deletes the branch named 'feature'

Solution

1. Step 1: Understand the git switch -c command

   The -c option means "create" a new branch and switch to it immediately.

2. Step 2: Apply to the branch name 'feature'

   The command creates a new branch called 'feature' and switches the working directory to it.

3. Final Answer:

   Creates a new branch named 'feature' and switches to it -> Option B

4. Quick Check:

   git switch -c = create and switch [OK]

Hint: Remember: -c means create and switch in one step [OK]

Common Mistakes:

• Thinking it only switches without creating
• Confusing with branch deletion commands
• Assuming it lists branches

2. Which of the following is the correct git switch syntax to create and switch to a new branch named dev?

easy

A. git switch -c dev

B. git switch dev -c

C. git checkout -b dev

D. git branch -c dev

Solution

1. Step 1: Recall the correct order of options in git switch

   The option -c must come before the branch name to create and switch.

2. Step 2: Check each option

   git switch -c dev is the correct syntax. git switch dev -c has wrong order. git checkout -b dev uses checkout instead of switch. git branch -c dev is invalid syntax.

3. Final Answer:

   git switch -c dev -> Option A

4. Quick Check:

   Correct syntax = git switch -c branch [OK]

Hint: Option -c always comes before branch name in git switch [OK]

Common Mistakes:

• Placing -c after branch name
• Confusing git switch with git branch
• Using git branch -c which is invalid

3. What will be the output of the following commands?

git switch -c test-branch
git branch --show-current

medium

A. Error: branch does not exist

B. main

C. No output

D. test-branch

Solution

1. Step 1: Create and switch to 'test-branch'

   The first command creates a new branch named 'test-branch' and switches to it.

2. Step 2: Show current branch

   The second command prints the name of the current branch, which is now 'test-branch'.

3. Final Answer:

   test-branch -> Option D

4. Quick Check:

   Current branch after switch -c = new branch name [OK]

Hint: After switch -c, current branch is the new branch [OK]

Common Mistakes:

• Assuming it stays on main branch
• Expecting no output from show-current
• Thinking it causes an error

4. You run git switch -c featureX but get an error: fatal: A branch named 'featureX' already exists. What should you do to switch to that branch?

medium

A. Run git switch featureX

B. Run git switch -c featureX again

C. Run git branch featureX

D. Run git checkout -b featureX

Solution

1. Step 1: Understand the error

   The error means the branch 'featureX' already exists, so you cannot create it again.

2. Step 2: Switch to existing branch

   Use git switch featureX without -c to switch to the existing branch.

3. Final Answer:

   Run git switch featureX -> Option A

4. Quick Check:

   Use switch without -c to switch existing branch [OK]

Hint: Use git switch without -c to switch existing branch [OK]

Common Mistakes:

• Trying to create branch again with -c
• Using git branch without switching
• Using checkout -b which creates new branch

5. You want to create a new branch named release-1.0 and immediately start working on it. Which command correctly does this and also sets the upstream to origin/release-1.0 in one step?

hard

A. git checkout -b release-1.0 origin/release-1.0

B. git branch release-1.0 && git switch release-1.0

C. git switch -c release-1.0 --track origin/release-1.0

D. git switch release-1.0 -c --set-upstream origin/release-1.0

Solution

1. Step 1: Understand creating and switching with upstream

   The git switch -c command can create and switch to a branch. The --track option sets the upstream branch.

2. Step 2: Analyze options

   git switch -c release-1.0 --track origin/release-1.0 creates the branch, switches to it, and sets upstream in one step. git branch release-1.0 && git switch release-1.0 requires two commands. git checkout -b release-1.0 origin/release-1.0 creates and switches from the remote commit and sets upstream automatically. git switch release-1.0 -c --set-upstream origin/release-1.0 has wrong option order and syntax.

3. Final Answer:

   git switch -c release-1.0 --track origin/release-1.0 -> Option C

4. Quick Check:

   Use switch -c with --track to create, switch, and set upstream [OK]

Hint: Use --track with switch -c to set upstream in one step [OK]

Common Mistakes:

• Not setting upstream in one step
• Using git branch and switch separately
• Wrong option order or syntax
