💡 Hint

Common Mistakes

Using incorrect config keys like 'branch' or 'initBranch'.

The correct git config key to set the default branch name is init.defaultBranch.

💡 Hint

Common Mistakes

Using 'default' or 'head' instead of 'defaultBranch'.

The key to get the default branch name is init.defaultBranch.

💡 Hint

Common Mistakes

Using 'branch' or hyphenated keys instead of 'defaultBranch'.

The correct key is init.defaultBranch. Other keys cause git to ignore or error.

4fill in blank

hard

Fill both blanks to set the default branch name to 'main' only for the current repository.

Git

git config [1] init.[2] main

Drag options to blanks, or click blank then click option'

A--local

B--global

Cbranch

DdefaultBranch

Attempts:

💡 Hint

Common Mistakes

Using --global instead of --local.

Using wrong config keys.

Use --local to set config for current repo and init.defaultBranch as the key.

5fill in blank

hard

Fill all three blanks to unset the default branch name configuration globally.

Git

git config [1] --unset init.[2]

Drag options to blanks, or click blank then click option'

A--local

B--global

Cbranch

DdefaultBranch

💡 Hint

Common Mistakes

Using --local instead of --global.

Using wrong keys.

To remove the global default branch name, use --global and the key init.defaultBranch.

Practice

1. What does the init.defaultBranch setting in Git control?

easy

A. The default user name for commits

B. The default remote repository URL

C. The default commit message template

D. The name of the main branch created when initializing a new repository

Solution

1. Step 1: Understand the purpose of init.defaultBranch

   This setting defines the branch name Git uses when you run git init to create a new repository.

2. Step 2: Identify what it controls

   It controls the default branch name, usually 'master' or 'main', for new repositories.

3. Final Answer:

   The name of the main branch created when initializing a new repository -> Option D

4. Quick Check:

   Default branch name = main branch name [OK]

Hint: Default branch name sets new repo's main branch [OK]

Common Mistakes:

• Confusing branch name with remote URL
• Thinking it sets commit message templates
• Assuming it sets user info

2. Which of the following commands correctly sets the default branch name to main globally in Git?

easy

A. git set defaultBranch main

B. git config --global defaultBranch main

C. git config --global init.defaultBranch main

D. git init --default-branch=main

Solution

1. Step 1: Recall the correct Git config syntax

   The correct syntax to set a global config is git config --global <key> <value>.

2. Step 2: Match the key for default branch name

   The key is init.defaultBranch, so the full command is git config --global init.defaultBranch main.

3. Final Answer:

   git config --global init.defaultBranch main -> Option C

4. Quick Check:

   Use git config --global init.defaultBranch [OK]

Hint: Use full key: init.defaultBranch with git config [OK]

Common Mistakes:

• Omitting 'init.' prefix in config key
• Using 'git set' instead of 'git config'
• Trying to set default branch during init command

3. After running git config --global init.defaultBranch develop, what will be the default branch name when you run git init in a new folder?

medium

A. master

B. develop

C. main

D. default

Solution

1. Step 1: Understand the effect of the config command

   Setting init.defaultBranch to 'develop' globally changes the default branch name for all new repos initialized after this.

2. Step 2: Predict the branch name after git init

   When you run git init, the initial branch will be named 'develop' instead of the usual 'master' or 'main'.

3. Final Answer:

   develop -> Option B

4. Quick Check:

   Config set to 'develop' means new repos start with 'develop' [OK]

Hint: New repos use branch name from init.defaultBranch [OK]

Common Mistakes:

• Assuming default stays 'master' or 'main'
• Confusing local repo branch with global config
• Thinking config affects existing repos

4. You tried to set the default branch name with git config --global init.defaultbranch main but new repos still use 'master'. What is the problem?

medium

A. The config key is case-sensitive; it should be init.defaultBranch

B. You need to restart your terminal for changes to apply

C. You must run git init with a special flag to use the new default

D. The default branch name cannot be changed globally

Solution

1. Step 1: Check the config key spelling

   Git config keys are case-sensitive. The correct key is init.defaultBranch with a capital 'B'.

2. Step 2: Understand why the setting didn't apply

   Using init.defaultbranch (lowercase 'b') creates a different config entry that Git ignores for default branch naming.

3. Final Answer:

   The config key is case-sensitive; it should be init.defaultBranch -> Option A

4. Quick Check:

   Config keys are case-sensitive in Git [OK]

Hint: Check exact case of config keys [OK]

Common Mistakes:

• Ignoring case sensitivity in config keys
• Thinking terminal restart is needed
• Believing default branch can't be changed

5. You want all new repositories on your system to start with the branch name stable. How do you set this globally and verify it?

hard

A. Run git config --global init.defaultBranch stable and then git config --global init.defaultBranch

B. Run git init --default-branch=stable and then git branch

C. Run git config --system init.defaultBranch stable and then git status

D. Run git set defaultBranch stable and then git config --list

Solution

1. Step 1: Set the global default branch name

   Use git config --global init.defaultBranch stable to set the default branch name for all new repos globally.

2. Step 2: Verify the setting

   Run git config --global init.defaultBranch to confirm the value is set to 'stable'.

3. Final Answer:

   Run git config --global init.defaultBranch stable and then git config --global init.defaultBranch -> Option A

4. Quick Check:

   Set with config, verify with config [OK]

Hint: Set and verify with git config commands [OK]

Common Mistakes:

• Using incorrect commands like git set
• Trying to verify with unrelated commands
• Using system config without permission
