These commands help you set up your Git environment and customize your workflow. Configuring Git properly ensures that your commits are attributed correctly and that your experience is tailored to your preferences. Here’s a step-by-step guide:

1. Set Your Username:
   git config --global user.name "Your Name"
   This command sets your name as it will appear in your commits.
2. Set Your Email Address:
   git config --global user.email "your.email@example.com"
   This sets the email address associated with your commits.
3. Check Your Configuration:
   git config --list
   Displays all your current Git configuration settings.
4. Set Your Default Editor (Optional):
   git config --global core.editor "code --wait"
   Replace code --wait with your preferred editor (e.g., nano, vim, notepad).
5. Set Line Ending Preferences (Optional):
   git config --global core.autocrlf true
   This is especially useful if you’re working across different operating systems (Windows, macOS, Linux).

These configuration steps are typically performed once per system and help ensure your Git environment is ready for version control and collaboration.

Git commands often support additional flags and options to help you tailor their behavior for specific tasks. Here’s a step-by-step guide to some of the most helpful ones:

1. Show a Short Status Summary:
   git status -s
   Provides a concise, easy-to-read summary of the current repository status.
2. View Concise Commit History:
   git log --oneline
   Displays the commit history in a compact, one-line-per-commit format.
3. See Staged Changes:
   git diff --staged
   Shows the differences between the staged changes and the last commit.
4. List All Branches (Local and Remote):
   git branch -a
   Lists all branches in your repository, including remote-tracking branches.
5. Show Remote Repository URLs:
   git remote -v
   Displays the URLs of all remotes associated with your repository.

These flags and options enhance your workflow by providing more control and visibility into your repository. Experiment with them to see how they can make your Git experience more efficient.

Even experienced Git users encounter issues. Here’s a step-by-step guide to essential troubleshooting and recovery commands that can help you fix common mistakes and recover lost work:

1. Undo the Last Commit (Keep Changes Staged):
   git reset --soft HEAD~1
   Moves the last commit back to the staging area, letting you edit or recommit as needed.
2. Undo the Last Commit (Discard Changes):
   git reset --hard HEAD~1
   Completely removes the last commit and any changes, so use with caution.
3. Remove Untracked Files:
   git clean -f
   Deletes files not tracked by Git. Add -d to also remove untracked directories.
4. Stash Uncommitted Changes:
   git stash
   Temporarily saves your uncommitted changes so you can work on something else.
5. Apply Stashed Changes:
   git stash pop
   Restores the most recently stashed changes back to your working directory.

These commands are invaluable for recovering from mistakes, cleaning up your working directory, or saving your progress temporarily. Always double-check before using commands that permanently remove data.

Following Git best practices helps you maintain a clean, organized, and collaborative codebase. Here’s a step-by-step guide to essential habits every developer should adopt:

1. Commit Often with Clear Messages:
   Make small, frequent commits and write descriptive messages that explain the purpose of each change. This makes it easier to track progress and troubleshoot issues.
2. Use Branches for Features and Fixes:
   Create separate branches for new features, bug fixes, or experiments. This keeps your main branch stable and makes collaboration smoother.
3. Pull Updates Regularly:
   Use git pull to fetch and integrate changes from the remote repository. This minimizes merge conflicts and keeps your local code up to date.
4. Review Changes Before Committing:
   Run git diff to review your changes before staging or committing. This helps catch mistakes early and ensures only intended changes are included.
5. Resolve Merge Conflicts Promptly:
   When conflicts arise, address them as soon as possible to avoid blocking your workflow or your team’s progress.
6. Keep the Repository Clean:
   Remove unused branches and regularly clean up untracked files with git branch -d branch-name and git clean -f.
7. Write .gitignore Files:
   Use a .gitignore file to exclude unnecessary files (like build artifacts or sensitive data) from your repository.
8. Backup and Push Frequently:
   Push your commits to the remote repository often to ensure your work is backed up and accessible to collaborators.

Adopting these best practices will help you and your team avoid common pitfalls, maintain a high-quality codebase, and collaborate more effectively with Git.
