Being a junior software engineer in a team means dealing with a shared code repository, and Git is a common choice for version control. Git’s stash operation is a lifesaver when you need to switch contexts swiftly. It allows you to temporarily save your changes without committing, providing a clean workspace for your new task. This article sheds light on how to use and undo git stash, and explores scenarios where it shines.

Understanding Git Stash:

Git stash takes your modified tracked files and staged changes, and saves them on a stack of unfinished changes that you can reapply at any time. It’s your magic wand whenever the need arises to clean the workspace momentarily.

Usage:

Stashing Changes:

• Use the command git stash to save your changes to a new stash entry.
• For a more descriptive approach, use git stash save "your message here" to attach a message with your stash.

Applying Stashed Changes:

• Bring back the stashed changes with git stash apply.
• If you have multiple stashes, use git stash list to view them and git stash apply stash@{n} (n is the number of the stash you want to apply from the list)to apply a specific stash.

Undoing Git Stash:

Dropping a Stash:

• If you no longer need the stashed changes, use git stash drop stash@{n} to remove a specific stash.

Popping a Stash:

• Use git stash pop to apply the latest stashed changes and remove them from the stash list.

Real-world Scenarios (actually used it for these exact instances during my internship):

• Emergency Bug Fixes: When an urgent bug fix comes in, git stash provides a clean slate to work on the fix without losing ongoing work.
• Testing Branches: If you need to switch between branches for testing, git stash helps in maintaining a clean workspace, enabling an easy transition.
• Code Reviews: Stash your changes to review a colleague’s code without the clutter of your own modifications.
• Merging Updated Upstream Changes: Before merging updated changes from the main branch, stashing your work ensures a clean merge, reducing the likelihood of conflicts.

Conclusion:

Mastering git stash early in your career simplifies context-switching, making you a more adaptable and efficient developer in a collaborative environment. So the next time you find yourself juggling between tasks, remember, git stash is your friend!
