Cancel File Change

Introduction

This challenge is designed to teach you how to use several important Git commands for managing changes and the commit history of a Git repository.

By the end of the challenge, you will know how to use the restore command to undo changes to a file in the working directory, the rm command to remove a file from the repository, and the reset command to undo the most recent commit.

Undo the Changes You Made

As a Git user, it's important to know how to undo changes you made to a file in the working directory. The restore command can be used to discard the changes and restore the file to its previous state.

Target

Your goal is to use the git restore command to undo changes you made to a file in a Git repository. Before you execute this command, you should go into the ~/myrepo directory to complete the operation.

Result Example

Here's an example of what you should be able to accomplish by the end of this challenge:

1. Make changes to the file myfile.txt in the working directory.

   On branch master
   Changes not staged for commit:
   (use "git add <file>..." to update what will be committed)
   (use "git restore <file>..." to discard changes in working directory)
   modified: myfile.txt

2. Use the restore command to undo the changes and restore the file myfile.txt to its previous state.

   On branch master
   nothing to commit, working tree clean

Requirements

To complete this lab, you will need:

• A Git repository with at least one commit.
• A basic understanding of Git concepts like commits, branches, and the staging area.

Remove a File From the Repository

As a Git user, it's important to know how to remove files from a Git repository. The git rm command can be used to remove a file from the repository and delete it from the working directory.

Target

Your goal is to use the git rm command to remove a file from a Git repository. Before you execute this command, you should go into the ~/myrepo directory to complete the operation.

Result Example

Here's an example of what you should be able to accomplish by the end of this challenge:

1. Create a file named newfile.txt in the repository, and commit to the local repository.

   commit 03d0a663bf2179dff0929166b63c62e8d367bc65 (HEAD -> master)
   Author: labex <labex@sample.com>
   Date:   Wed Mar 8 17:34:23 2023 -0800
   
       add newfile.txt

2. Use the rm command to remove the file from the repository.

   On branch master
   Changes to be committed:
   (use "git reset HEAD <file>..." to unstage)
   
   deleted: newfile.txt

3. Create a new commit in the repository.

   commit 9362c054937cb54c27a02aeb8a405ce33412f09a (HEAD -> master)
   Author: labex <labex@example.com>
   Date:   Wed Mar 8 17:50:54 2023 -0800
   
       delete newfile.txt

Requirements

To complete this challenge, you will need:

• A Git repository with at least one commit.
• A basic understanding of Git concepts like commits, branches, and the staging area.

Undo and Reset

As a Git user, it's important to know how to undo commits and reset the current branch to a previous commit. The reset command can be used to undo the most recent commit and reset the current branch to the previous commit.

Target

Your goal is to use the reset command to undo the most recent commit and reset the current branch to a previous commit. Before you execute this command, you should go into the ~/myrepo directory to complete the operation.

Result Example

Here's an example of what you should be able to accomplish by the end of this challenge:

1. Use the reset command to undo the most recent commit and reset the current branch to the previous commit.

   Unstaged changes after reset:
   D newfile.txt

Requirements

To complete this lab, you will need:

• A Git repository with at least one commit.
• A basic understanding of Git concepts like commits, branches, and the staging area.

Summary

To complete this challenge, you will need a Git repository with at least one commit, and a basic understanding of Git concepts like commits, branches, and the staging area.

You will follow three steps: using the restore command to undo changes to a file in the working directory, using the rm command to remove a file from the repository, and using the reset command to undo the most recent commit and reset the current branch to a previous commit.

By the end of the challenge, you will have a better understanding of how to manage changes and the commit history in your Git repository.
