Creating and switching in one step in Git - Quick Revision & Summary

Recall & Review

beginner

What git command creates a new branch and switches to it immediately?

The command git switch -c <branch-name> creates a new branch and switches to it in one step.

beginner

What does the -c option do in git switch -c?

The -c option stands for 'create'. It tells git to create a new branch before switching to it.

beginner

How would you create and switch to a branch named feature1?

Use the command git switch -c feature1. This creates the branch feature1 and switches to it.

intermediate

What is the difference between git checkout -b and git switch -c?

git checkout -b also creates and switches to a new branch, but git switch -c is a newer, clearer command introduced to separate switching branches from other checkout tasks.

beginner

Can you switch to an existing branch using git switch?

Yes, simply use git switch <branch-name> without -c to switch to an existing branch.

Which command creates and switches to a new branch named 'dev' in one step?

A git switch dev

B git branch dev

C git switch -c dev

D git checkout dev

git switch -c dev creates the new branch 'dev' and switches to it immediately.

What does the command git switch -c feature do?

A Creates a new branch named 'feature' and switches to it

B Deletes the branch named 'feature'

C Switches to an existing branch named 'feature'

D Lists all branches

The -c option creates a new branch before switching to it.

Which command is the newer, clearer way to create and switch branches in git?

A git checkout -b

B git switch -c

C git branch -c

D git create -s

git switch -c is the newer command designed for creating and switching branches.

How do you switch to an existing branch named 'main' using git switch?

A git switch main

B git switch -c main

C git checkout -b main

D git branch main

git switch main switches to the existing branch 'main'.

What happens if you run git switch -c with a branch name that already exists?

A Git deletes the existing branch and creates a new one

B Git creates a new branch with the same name

C Git switches to the existing branch

D Git shows an error that the branch already exists

Git will show an error because the branch name already exists and cannot be created again.

Explain how to create a new branch and switch to it in one step using git.

Think about the command that combines creation and switching.

Describe the difference between git checkout -b and git switch -c.

Focus on the purpose and clarity of the commands.

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
