Git Commit Basics Quiz

The command `git add` stages changes in your working directory, preparing them for the next commit. By using this command, you specify which modified files should be included in the upcoming commit, ensuring that only the desired changes are recorded in the project's history.

The command `git commit -m` is used to create a new commit in Git with changes that have been staged. The `-m` option allows the user to include a message describing the commit, making it easier to understand the purpose of the changes made.

The command 'git commit -m' is used to create a new commit in a Git repository, allowing the user to include a descriptive message that explains the changes made. This message helps in tracking the history of changes, making it easier to understand the purpose of each commit.

A commit message should effectively communicate the purpose of the changes made in the code. Being clear ensures that others can easily understand the intent behind the commit, while being concise helps to convey the message without unnecessary details, making it easier to read and reference in the future.

In version control systems like Git, changes must be staged before committing. Staging allows you to select specific modifications to include in the next commit, ensuring that only intended changes are recorded in the project history. Therefore, committing changes without staging them first is not possible.

The command "git log" displays the commit history in a Git repository. It lists all the commits made, along with their unique identifiers, authors, dates, and messages, allowing users to track changes and understand the project's evolution over time. Other options are not valid Git commands for this purpose.

'git status' provides an overview of the current state of the working directory and staging area. It shows which branch you are on and highlights any changes that have not yet been staged for commit, allowing developers to keep track of their modifications and manage their workflow effectively.

A good commit message begins with a verb to clearly convey the action taken in the commit. This approach helps maintain consistency and clarity, making it easier for others to understand the purpose of the changes. Starting with a verb also encourages a more active and direct tone, enhancing the overall communication within the project's history.

A commit in version control systems captures the current state of the codebase, effectively creating a snapshot at that moment. This allows developers to track changes over time, revert to previous states, and collaborate more effectively by maintaining a history of modifications.

The `git diff` command displays the differences between the working directory and the staging area, highlighting changes that have not yet been staged for commit. It allows users to review modifications before deciding to stage them, ensuring a clearer understanding of what will be included in the next commit.

The 'staging area' in version control systems, such as Git, is referred to as the index because it serves as a temporary space where changes are gathered and prepared before being committed to the repository. This allows for selective inclusion of changes in the final commit, making it easier to manage modifications.

'git reset' is a command in Git that allows you to undo commits by moving the current branch pointer back to a previous commit. This effectively removes the specified commit from the history, making it possible to modify or discard changes made in that commit.
