Git, an essential tool in the world of DevOps and Cloud Native Computing, can sometimes throw you for a loop with its myriad of commands. Today, we'll demystify six of the most commonly misunderstood Git commands: git merge, git rebase, git reset, git revert, git fetch, and git pull.
Setting the Scene:
We're enhancing KodeKloud's e-learning portal with an interactive quiz module. This new feature has multiple components: UI design, backend logic, question databank, and scoring algorithms.
1. git merge - Merging the Question Databank
You've built a databank of questions on a separate branch called
questions-databank. This databank is now complete, and you want to integrate it with the main application on the
After rigorous reviews and testing, you feel confident about your databank's quality and want to merge it.
# Switch to the main application codebase git checkout master # Integrate the databank git merge questions-databank
master branch will have the latest questions integrated and ready for the quiz UI to fetch.
2. git rebase - Keeping Backend Development Linear
While building the scoring algorithm on the
master branch received updates like bug fixes and performance enhancements. To ensure a linear and clean commit history, you'll use
Before finalizing the scoring mechanism, you'll pull in the latest changes from
git checkout scoring-algo-branch # Rebase to get the latest updates from master git rebase master
Post-rebase, your feature branch has both the scoring logic and the recent updates from the master.
3. git reset - Realizing the Scoring Glitch
Post-committing, you detected a miscalculation in your scoring mechanism. The latest commit needs to be undone.
Undo the last commit and return to the previous state, allowing for the bug to be fixed.
# Review the commit history git log # Return to the state before the latest commit git reset HEAD~1

4. git revert - Maintaining Shared Repository Integrity
You had already pushed the commit with the glitch to a shared remote repository. To maintain a transparent commit history, you'll use
Undo the changes of the buggy commit but keep a record of both the erroneous commit and the fix.
# Revert the problematic commit git revert [commit_hash_of_the_glitch]
5. git fetch - Staying in the Loop
Your colleague is refining the UI on a separate branch. Before finalizing your backend updates, you wish to see their progress without merging their changes.
Fetch their updates without altering your current branch.
git fetch origin
6. git pull - Syncing Up for the Final Push
Your updates are ready, and before pushing, you want to ensure you have the latest code from the main repository.
Retrieve and merge updates from the remote repository to avoid conflicts.
# Fetch and merge from the main repository git pull origin master

Mastering Git commands is vital for efficient collaboration and project management in today's tech landscape. By understanding the nuances and real-world applications of these six commands, you're well on your way to becoming a Git pro!
