Git Commands Every Developer Should Know for Faster Workflow
Master the essential Git commands and workflows that will dramatically improve your development speed. Whether you're working solo or in a team, these Git techniques will help you manage code more efficiently.
1. Essential Git Commands
Master these fundamental Git commands to build a solid foundation for efficient version control. These commands form the core of daily Git operations.
Repository Setup
# Initialize a new repository git init # Clone existing repository git clone# Add remote repository git remote add origin # Check repository status git status
Basic Operations
# Stage changes git addgit add . # Stage all changes # Commit changes git commit -m "descriptive message" # Push changes git push origin # Pull updates git pull origin
Command Tips
Best Practices
- • Use meaningful commit messages
- • Commit related changes together
- • Commit early and often
Common Mistakes
- • Committing without checking status
- • Pushing without pulling first
- • Using vague commit messages
2. Branch Management
Effective branch management is crucial for maintaining a clean and organized codebase. Learn how to create, switch, and manage branches efficiently for better workflow.
Branch Operations
# Create and switch to new branch
git checkout -b feature/new-feature
# Switch to existing branch
git checkout main
# List all branches
git branch --all
# Delete branch
git branch -d feature/old-feature
# Force delete unmerged branch
git branch -D feature/abandoned
Remote Branches
# Push branch to remote
git push -u origin feature/new-feature
# Track remote branch
git branch --track feature/remote origin/feature/remote
# Update remote branches
git fetch origin
# Delete remote branch
git push origin --delete feature/old-feature
Branch Naming Conventions
Common Prefixes
- feature/ New features or enhancements
- bugfix/ Bug fixes and patches
- hotfix/ Urgent production fixes
- release/ Release preparation
Naming Examples
- ✓ feature/user-authentication
- ✓ bugfix/login-validation
- ✗ new-stuff
- ✗ fix123
Branch Management Tips
Best Practices
- • Keep branches focused and short-lived
- • Regularly sync with main branch
- • Delete merged branches promptly
When to Branch
- • New features or improvements
- • Bug fixes and patches
- • Experimental changes
3. Merge vs Rebase
Understanding the difference between merge and rebase is crucial for maintaining a clean Git history. Learn when to use each approach for better collaboration and code management.
Merge Workflow
# Merge main into feature branch
git checkout feature/new-feature
git merge main
# Create a merge commit
git merge --no-ff feature/new-feature
# Abort a merge with conflicts
git merge --abort
When to Merge
- • Preserving feature branch history
- • Collaborating on shared branches
- • Maintaining topic branches
Rebase Workflow
# Rebase feature branch onto main
git checkout feature/new-feature
git rebase main
# Interactive rebase for cleanup
git rebase -i HEAD~3
# Continue after resolving conflicts
git rebase --continue
# Abort rebase operation
git rebase --abort
When to Rebase
- • Cleaning up local changes
- • Maintaining linear history
- • Working on personal branches
Comparison Overview
Merge
- ✓ Preserves complete history
- ✓ Non-destructive operation
- ✗ Can create complex history
- ✗ More merge commits
Rebase
- ✓ Creates linear history
- ✓ Cleaner project history
- ✗ Rewrites commit history
- ✗ Can be complex to resolve conflicts
Golden Rules
Never rebase shared branches: Only rebase branches that you haven't pushed or that no one else is working on.
Merge for collaboration: Use merge when working on shared feature branches or with multiple contributors.
Rebase for cleanup: Use rebase to clean up your local work before merging into the main branch.
4. Conflict Resolution
Dealing with merge conflicts effectively is essential for smooth collaboration. Learn how to resolve conflicts confidently and maintain code integrity.
Understanding Conflicts
<<<<<<< HEAD
function greeting() {
return 'Hello World';
}
=======
function greeting() {
return 'Hi there!';
}
>>>>>>> feature/new-greeting
# Conflict markers explained:
# <<<<<<< HEAD - Current changes
# ======= - Divider
# >>>>>>> branch-name - Incoming changes
Resolution Commands
# Check files with conflicts git status # After resolving conflicts git addgit commit -m "Resolve merge conflicts" # Use visual tool for conflicts git mergetool # Abort merge if needed git merge --abort
Resolution Strategies
Manual Resolution
- 1. Open conflicted files
- 2. Identify conflict markers
- 3. Choose or combine changes
- 4. Remove conflict markers
- 5. Test the resolution
Using Tools
- • VS Code Git integration
- • GitKraken
- • Meld
- • Beyond Compare
Conflict Prevention Tips
Before Merging
- • Pull latest changes frequently
- • Communicate with team members
- • Keep branches short-lived
Best Practices
- • Understand both changes
- • Test after resolution
- • Document significant resolutions
5. Git Aliases for Speed
Git aliases can significantly speed up your workflow by creating shortcuts for frequently used commands. Learn how to set up and use aliases effectively.
Setting Up Aliases
# Add alias to Git config
git config --global alias.co checkout
git config --global alias.br branch
git config --global alias.ci commit
git config --global alias.st status
# Create complex alias
git config --global alias.lg "log --graph --oneline --decorate"
Common Aliases
# Usage examples
git st # git status
git co feature # git checkout feature
git br -a # git branch --all
git ci -m "msg" # git commit -m "msg"
git lg # Pretty log view
Recommended Aliases
Basic Operations
[alias]
aa = add --all
cm = commit -m
ps = push
pl = pull
ft = fetch --all
rb = rebase
cp = cherry-pick
Advanced Operations
[alias]
unstage = reset HEAD --
last = log -1 HEAD
visual = !gitk
uncommit = reset --soft HEAD^
amend = commit --amend
Productivity Tips
Creating Aliases
- • Keep aliases short but meaningful
- • Use consistent naming patterns
- • Document complex aliases
Shell Integration
- • Combine with shell aliases
- • Create custom scripts
- • Use tab completion
