Git is a powerful version control system, and knowing the right tips and tricks can significantly improve your workflow. This guide covers essential Git tips that every developer should know.

What You’ll Learn

• Essential Git commands
• Productivity tips
• Best practices
• Common workflows
• Troubleshooting tricks

Implementation Steps

1. Basic Git Configuration

   # Set up your identity
   git config --global user.name "Your Name"
   git config --global user.email "your.email@example.com"
   
   # Configure default editor
   git config --global core.editor "code --wait"
   
   # Set default branch name
   git config --global init.defaultBranch main
   
   # Configure line endings
   git config --global core.autocrlf input  # for macOS/Linux
   git config --global core.autocrlf true   # for Windows
   

   • Set identity
   • Configure editor
   • Set defaults
   • Handle line endings

2. Useful Aliases

   # Add common aliases
   git config --global alias.st status
   git config --global alias.co checkout
   git config --global alias.br branch
   git config --global alias.ci commit
   git config --global alias.unstage 'reset HEAD --'
   git config --global alias.last 'log -1 HEAD'
   git config --global alias.visual '!gitk'
   

   • Create shortcuts
   • Save time
   • Improve workflow
   • Customize commands

3. Efficient Committing

   # Stage specific changes
   git add -p  # Interactive staging
   
   # Create meaningful commits
   git commit -m "feat: add user authentication"
   git commit -m "fix: resolve login bug"
   git commit -m "docs: update README"
   
   # Amend last commit
   git commit --amend --no-edit  # Keep message
   git commit --amend -m "New message"  # Change message
   

   • Stage selectively
   • Write good messages
   • Fix mistakes
   • Follow conventions

4. Branch Management

   # Create and switch
   git checkout -b feature/new-feature
   
   # List branches
   git branch -v  # Show last commit
   git branch -vv  # Show tracking info
   
   # Clean up branches
   git branch --merged | grep -v "\*" | xargs -n 1 git branch -d
   git remote prune origin  # Clean remote refs
   

   • Create branches
   • Track changes
   • Clean up
   • Stay organized

Best Practices

1. Commit Messages

   • Use present tense
   • Be specific
   • Follow conventions
   • Keep it concise

2. Branch Strategy

   • Meaningful names
   • Short-lived branches
   • Regular cleanup
   • Clear purpose

3. Code Review

   • Small commits
   • Clear changes
   • Good descriptions
   • Follow standards

4. Security

   • Protect sensitive data
   • Use .gitignore
   • Review changes
   • Secure credentials

Common Use Cases

1. Undoing Changes

   # Discard working changes
   git checkout -- file.txt
   git restore file.txt  # Git 2.23+
   
   # Reset to specific commit
   git reset --soft HEAD~1  # Keep changes staged
   git reset --mixed HEAD~1  # Keep changes unstaged
   git reset --hard HEAD~1  # Discard changes
   
   # Revert a commit
   git revert HEAD  # Undo last commit
   git revert <commit-hash>  # Undo specific commit
   

2. Stashing

   # Save changes
   git stash save "Work in progress"
   git stash push -m "Work in progress"
   
   # List stashes
   git stash list
   
   # Apply stashes
   git stash apply stash@{0}
   git stash pop  # Apply and remove
   
   # Clear stashes
   git stash drop stash@{0}
   git stash clear
   

3. Logging

   # View history
   git log --oneline  # Compact view
   git log --graph --oneline --all  # Visual history
   git log -p  # Show changes
   git log --stat  # Show stats
   
   # Search history
   git log -S "search term"  # Search content
   git log --author="name"  # Search author
   git log --since="2 weeks ago"  # Time-based
   

4. Merging

   # Merge strategies
   git merge --no-ff feature  # Keep history
   git merge --squash feature  # Single commit
   git merge --abort  # Cancel merge
   
   # Resolve conflicts
   git status  # Check conflicts
   git diff  # View differences
   git add .  # Mark resolved
   git commit  # Complete merge
   

Advanced Usage

1. Rebasing

   # Interactive rebase
   git rebase -i HEAD~3  # Last 3 commits
   git rebase -i origin/main  # Rebase on main
   
   # Continue/abort
   git rebase --continue
   git rebase --abort
   
   # Skip commit
   git rebase --skip
   

2. Cherry-picking

   # Pick specific commits
   git cherry-pick <commit-hash>
   git cherry-pick -x <commit-hash>  # Add reference
   
   # Multiple commits
   git cherry-pick <commit1> <commit2>
   git cherry-pick <commit1>..<commit2>
   

3. Submodules

   # Add submodule
   git submodule add <repository-url>
   
   # Update submodules
   git submodule update --init --recursive
   git submodule update --remote
   
   # Remove submodule
   git submodule deinit <path>
   git rm <path>
   

4. Hooks

   # Create hook
   touch .git/hooks/pre-commit
   chmod +x .git/hooks/pre-commit
   
   # Example pre-commit
   #!/bin/sh
   npm run lint
   npm run test
   

Common Issues and Solutions

1. Merge Conflicts

   # View conflicts
   git diff --name-only --diff-filter=U
   
   # Use visual tools
   git mergetool
   
   # Abort merge
   git merge --abort
   

2. Lost Commits

   # Find lost commits
   git reflog
   git fsck --lost-found
   
   # Recover commit
   git reset --hard <commit-hash>
   

3. Large Files

   # Find large files
   git rev-list --objects --all | grep "$(git verify-pack -v .git/objects/pack/*.idx | sort -k 3 -n | tail -10 | awk '{print$1}')"
   
   # Clean history
   git filter-branch --force --index-filter 'git rm --cached --ignore-unmatch path/to/large/file' --prune-empty --tag-name-filter cat -- --all
