1Which command initializes a new Git repository in an existing directory?
Which command initializes a new Git repository in an existing directory?
Answer
The git init command creates a new Git repository in the current directory by initializing the .git subdirectory containing all files needed for versioning. This command is the first step to start tracking changes in an existing project.
2What is the difference between git clone and git init?
What is the difference between git clone and git init?
Answer
git init creates a new empty repository in the current directory, while git clone copies an existing remote repository to the local machine, including the full commit history and branches. git clone also automatically sets up the connection with the remote repository (origin).
3Which command creates a new branch and switches to it in a single operation?
Which command creates a new branch and switches to it in a single operation?
Answer
The command git checkout -b branch_name creates a new branch and immediately switches to it. Since Git 2.23, git switch -c branch_name can also be used and is more explicit. These commands avoid doing git branch followed by git checkout.
What is the main difference between git merge and git rebase?
Why should rebasing commits already pushed to a shared branch be avoided?
