What is Git primarily used for?
Tracking and managing changes in source code
Designing graphic interfaces
Compiling programs
Managing databases
Git is a distributed version control system used to track changes in code over time. It enables collaboration among multiple developers and maintains a history of modifications.
Which command initializes a new Git repository?
git init
git start
git create
git new
The 'git init' command sets up a new Git repository by creating a .git subdirectory. This prepares the folder to start tracking file changes.
What is a commit in Git?
A snapshot of the current project state
A process to merge branches
A copy of the repository
A reference to a remote repository
A commit captures the state of your project at a particular point in time. This allows you to track changes and revert to previous states if necessary.
What is the purpose of the staging area in Git?
To prepare changes before committing
To permanently store files
To compile project code
To merge different branches
The staging area, or index, is where you place changes that you want to include in your next commit. It allows you to review and organize modifications before saving them permanently in the repository.
Which Git command displays the commit history?
git log
git history
git commits
git status
The 'git log' command shows the commit history in a repository, displaying commit messages, dates, and authors. This helps in tracking the evolution of the project over time.
Which command is used to create a new branch in Git?
git branch [branchname]
git checkout [branchname]
git create [branchname]
git init [branchname]
The 'git branch' command followed by a branch name creates a new branch in your repository. This allows you to develop features or fixes in isolation from the main codebase.
Which command is typically used to switch between branches in Git?
git checkout
git branch
git merge
git commit
The 'git checkout' command is traditionally used to switch from one branch to another, updating your working directory accordingly. Although newer commands exist, 'git checkout' remains widely used.
What does the 'git merge' command do?
It combines changes from one branch into another
It creates a new branch
It discards all local changes
It clones a repository
The 'git merge' command integrates changes from one branch into your current branch. This is essential for combining different lines of development.
Which Git command displays the current status of the repository?
git status
git log
git diff
git branch
The 'git status' command reveals which files are modified, staged, or untracked in your repository. This information is crucial for understanding the state of your working directory before committing.
What is the purpose of the 'git clone' command?
It creates a local copy of a remote repository
It uploads local commits to a remote repository
It merges two different repositories
It initializes a new repository
The 'git clone' command copies an existing repository from a remote source to your local machine. This allows you to work on a project locally while staying connected to its remote version.
Why would you use the 'git pull' command?
To fetch and integrate changes from a remote repository
To push local commits to the remote repository
To create a new branch
To view the commit history
The 'git pull' command updates your local repository by fetching changes from a remote source and merging them into your current branch. This helps in staying synchronized with team contributions.
How do you unstage changes that have been added to the staging area?
git reset
git revert
git checkout
git commit --amend
The 'git reset' command removes changes from the staging area, moving them back to the working directory. This is useful if you decide not to include certain changes in your next commit.
What does 'git remote -v' display?
The list of remote repositories and their URLs
The full commit history
The list of local branches
Information about the current branch
The 'git remote -v' command shows all remote repositories linked to your project along with their associated URLs. This helps confirm where your repository is connected for fetching and pushing changes.
When would you use 'git rebase' instead of 'git merge'?
To create a linear commit history by reapplying commits
To delete a branch
To split a commit into smaller commits
To clone a repository
The 'git rebase' command repositions commits on top of another base tip, resulting in a linear commit history. This can lead to a cleaner history compared to merge commits.
What is the purpose of the .gitignore file in a repository?
To specify files and directories that Git should ignore
To list all files tracked by Git
To merge changes from remote repositories
To store commit messages
The .gitignore file tells Git which files or directories to exclude from version control. This is particularly useful for ignoring temporary files, logs, or build artifacts that do not need to be tracked.
How can you view differences between your working directory and the staging area?
git diff
git status
git log
git merge
The 'git diff' command shows the changes between various states, such as between the working directory and the staging area. This provides a detailed look at what has been modified before a commit is made.
What should you do when a merge conflict occurs in Git?
Manually resolve the conflicts in the affected files
Run git reset --hard to discard changes
Delete the repository and start over
Ignore the conflict and commit the changes anyway
When Git encounters conflicting changes during a merge, it marks the conflicts within the affected files. You need to edit these files to resolve the differences, then stage and commit the resolved changes.
How do you discard local changes in a file that has not been staged?
git checkout --
git revert
git reset
git clean
The command 'git checkout -- ' replaces the local version of the file with the version from the last commit, effectively discarding unstaged changes. This is useful when you want to undo modifications without affecting the commit history.
What does the 'git stash' command do?
It temporarily saves changes that are not ready to be committed
It permanently removes untracked files
It clones the repository
It resets the repository to a previous commit
The 'git stash' command allows you to set aside changes in your working directory temporarily. This is especially useful when you need to switch branches or work on a different task without committing incomplete work.
Which command provides a summary of differences, including insertions and deletions, between commits?
git diff --stat
git log
git status
git show
The 'git diff --stat' command generates a concise summary of changes between commits, highlighting the number of insertions and deletions. This quick overview helps you understand the extent of modifications between versions.
