Jagroop Singh20 Git Command-Line Tricks Every Developer Should Know
Git is an essential version control tool for developers. Although GUI tools can simplify some tasks, mastering the Git command line offers deeper control, flexibility, and speed. Here are 20 Git command-line tricks that every developer should know to streamline their workflow.
1. Set Global Configuration
Ensure your commits are tagged with the correct identity.
git config --global user.name "Your Name"
git config --global user.email "you@example.com"
💡 Tip: Use --local instead of --global to set project-specific configurations.
2. Undo the Last Commit (without losing changes)
If you made a mistake in the last commit, you can undo it.
git reset --soft HEAD~1
This leaves your changes staged, so you can amend the commit or fix the issue.
3. Amend the Last Commit
Forgot to include a change or want to update the commit message?
git add .
git commit --amend -m "Updated commit message"
This updates the previous commit without creating a new one.
4. Stash Uncommitted Changes
Need to quickly switch branches without committing?
git stash
💡 Retrieve the stash later with:
git stash pop
5. View Commit History Graphically
Visualizing the commit history makes it easier to understand the project's state.
git log --graph --oneline --all
6. Change the Commit Author
Change the author of the last commit.
git commit --amend --author="New Author <newauthor@example.com>"
7. Check Differences in Staged Changes
Use git diff to compare files at different stages.
git diff --staged
This shows the changes that are staged but not yet committed.
8. Find a Bug with Bisect
Use git bisect to find the commit that introduced a bug.
git bisect start
git bisect bad # Current commit is bad
git bisect good <commit-hash> # A known good commit
Git will walk through the commit history to identify the problematic commit.
9. Rebase for a Clean Commit History
Rebasing rewrites your commit history for clarity.
git rebase -i HEAD~3
This lets you edit, squash, or reorder your last 3 commits.
10. Cherry-Pick Specific Commits
Want to bring a specific commit from another branch?
git cherry-pick <commit-hash>
11. List All Branches (Local and Remote)
See which branches are available.
git branch -a
12. Clean Untracked Files and Directories
Quickly remove unwanted files that are not tracked by Git.
git clean -fd
💡 Use -n for a dry run to preview what will be removed.
13. Track an Upstream Branch
Keep your local branch in sync with a remote branch.
git branch --set-upstream-to=origin/main
14. Squash Commits with Interactive Rebase
Combine multiple commits into one.
git rebase -i HEAD~n # Replace 'n' with the number of commits
15. View the File at a Specific Commit
Check a file's state at a particular commit.
git show <commit-hash>:path/to/file
16. Edit the .gitignore After Committing
If you forgot to ignore certain files, update .gitignore.
echo "node_modules/" >> .gitignore
git rm -r --cached node_modules/
git commit -m "Update .gitignore"
17. Revert a Pushed Commit
Undo changes from a specific commit without changing history.
git revert <commit-hash>
18. Fetch Only Metadata
Want to avoid fetching the whole repository?
git fetch --dry-run
This lets you see what would be fetched without actually downloading data.
19. Blame a Line of Code
Find out who wrote a specific line in a file.
git blame path/to/file
20. Reset a File to the Last Commit
Discard local changes to a specific file.
git checkout -- path/to/file
These 20 Git command-line tricks can make your development process smoother, whether you are working alone or with a team. While GUI tools offer convenience, mastering the Git command line provides more control over your workflows. Try out these commands and elevate your Git skills!
