Advanced Git Techniques for DevOps

Git, the widely used distributed version control system, is known for its flexibility and robust features. In this blog post, we'll explore several advanced Git techniques that empower developers to streamline their workflows and tackle complex version control scenarios. From cherry-picking specific commits to mastering the art of rebasing and squashing, let's delve into the world of Advanced Git.

1. Git Cherry-Pick: Selective Commit Integration

Git cherry-pick is a powerful command that allows developers to selectively apply specific commits from one branch to another. This is particularly useful when you want to bring in individual changes without merging entire branches. The syntax is straightforward:

    git cherry-pick <commit-hash>    

This command copies the changes from the specified commit and applies them to the current working branch. It's a handy tool for incorporating critical bug fixes or essential features without the need for a full branch merge.

2. Git Stash, Drop & Pop: Temporary Work Area Management

Git stash is a lifesaver when you need to save your current changes without committing them. It allows you to stash away your modifications and switch to another branch or perform other operations. The stash can be applied later or discarded.

• To stash changes: git stash save "message"
• To apply the stash: git stash apply
• To drop the stash: git stash drop
• To pop the stash (apply and drop): git stash pop

These commands provide a flexible way to manage your work temporarily and keep your working directory clean.

3. Git Rebase: Rewrite History with Precision

Git rebase is a powerful but potentially risky command that allows developers to rewrite commit history. It's particularly useful for creating a linear and cleaner history by incorporating changes from one branch into another.

git rebase -i <base-branch>

This opens an interactive interface where you can squash, edit, reorder, or even drop commits. Exercise caution when using rebase, especially on shared branches, as it modifies commit history.

4. Git Squash: Condensing Commits for Clarity

Git squash is a technique used during interactive rebase to combine multiple commits into a single, more meaningful commit. This helps maintain a clean and concise commit history, making it easier to understand and review. During interactive rebase, mark the commits you want to squash with "squash" or "s" and proceed with the rebase.

git rebase -i <base-branch>
