What is Git Stash?

Let’s start with the basics: the Git Stash is a kind of temporary storage area in Git where you can keep unconfirmed changes without losing them. You might be working on a feature, but suddenly need to switch to another branch to fix a bug or attend a meeting. But you don’t want to transfer your half-finished work and lose it at the same time. This is where git stash comes into play.

You can think of it like a digital “desk drawer” for your work in progress. You hide your changes for later, tidy up your workspace and when you’re ready to continue working, you take them out again and pick up exactly where you left off.

Why you need Git Stash

Why is git stash so useful? Here are some common scenarios where it comes in handy:

• Quickly switching branches: If you need to switch to another branch to check something or fix a bug, but don’t want to commit your current work, you can store it in the stash.
• Keeping the working directory clean: Git encourages you to commit your code often, but what if you’ve made changes that aren’t ready to be committed? With stashing, you can set those changes aside and keep your working directory clean.
• Multitasking: Sometimes you get interrupted by an urgent task or other work. Instead of undoing your changes or making unnecessary commits, put your current work aside and come back to it later.

Basic use of Git Stash

Now that you know why git stash is useful, let’s look at its basic usage. The beauty of git stash is that it’s so simple that even as a beginner you’ll quickly get the hang of it.

How to save your changes

To cache your changes, simply run :

bash git stash

This command saves your changes, including tracked and untracked files, and resets your working directory to the last commit. Basically, it’s like setting the current state of your work to “pause”.

Viewing your stashes

After stashing, you may want to see which stashes you have created. Git saves a list of all your stashes in the stash stack. To view them, run :

git stash list

You’ll see a list that looks something like this:

stash@{0}: WIP on feature-branch: a123456 Initial commit stash@{1}: WIP on feature-branch: 0987654 Feature X added

This list shows the stashes you have created, along with the branch they were created from and the commit hash.

Apply stashed changes

To apply the changes from your last stash back to your working directory, use

git stash apply

This command leaves the stash in the stash list, but applies the changes to your current working directory. If you want to apply a specific stash, you can reference it via its index:

git stash apply stash@{1}

Delete a stash

If you no longer need a stash and want to delete it, use :

git stash drop stash@{0}

This will remove the stash from the list and free up space. If you want to delete all stashes at once, execute :

git stash clear

But be careful: once a stash has been cleared, it’s gone forever!

Advanced Git stash commands

Once you’re familiar with the basics, there are some advanced ways to use `git stash` that make it even more powerful.

Stash specific files

Sometimes you may not want to stash everything — maybe there’s just one file you want to stash temporarily. To stash specific files, you can use the following:

git stash push

For example:

git stash push src/app.js

As a result, the changes are only saved in `src/app.js`, other files remain unaffected.

Creating a branch from a Stash

If you realize that the work you have hidden actually deserves its own branch, you can create a new branch from the stash:

git stash branch

This will automatically apply the stash to the new branch and check it out.

Stash Pop vs. Stash Apply

You may notice two commands that seem to do the same thing: `stash apply` and `stash pop`. Here is the crucial difference:

– `git stash apply`: This command applies the stash, but keeps it in the stash list.
– `git stash pop`: The stash is applied and then removed from the stash list.

So if you know that you no longer need the stash, “stash pop” is the right way for you.

Keep or discard changes after the stash

Sometimes you want to stash changes but keep certain unconfirmed files in your working directory. You can use the `–keep-index` option for this:

`bash git stash push –keep-index

This will only cache the files that have not been transferred and the rest will remain intact.

Common Git Stash use cases

Now that you know how to use Git stash, let’s look at some real-world use cases where you can utilize it the most.

Interruptions during coding

Imagine you’re working on a new feature, but your boss comes by and tells you to fix a bug right away. You’re halfway through your work and don’t want to hand over the code unfinished. A perfect scenario for git stash!

git stash git checkout bugfix-branch

Now you can fix the bug, and when you’re done:

bash git checkout feature-branch git stash pop

And you’re right back where you left off!

Switch between branches

Sometimes you need to switch branches to try something out or run a test. Git won’t let you switch between branches if you have uncommitted changes, but you also don’t want to commit a bunch of changes at random. Here’s how to use `git stash` to solve this problem:

git stash git checkout another-branch
Do what you need to do git checkout feature-branch git stash pop

Clean up uncommitted changes

Suppose you’ve experimented with different approaches and now want to clean up your working directory without committing your failed attempts. Instead of losing the work, you hide it:

git stash git stash apply

This will make it easier for you to remember the contents of the individual stashes when you list them later.

Later you can go through the stash to find all the useful parts.



Best practices for using Git Stash

As with any tool, there are right and wrong ways to use Git stash. Here are some best practices to make sure you’re using it efficiently.

Name your stashes

If you have multiple stashes, it can be confusing to keep track of what each one stands for. That’s why it’s a good idea to give your stashes meaningful names:

git stash push -m “In progress on feature X”

Manage multiple stashes

You may end up with several stashes over time. Don’t let them pile up! Regularly clear out the stashes that you no longer need:

 git stash drop

or

bash git stash clear

Know when not to use Stash

While `git stash` is great, it’s not a panacea. When your changes are ready for review or collaboration, it’s better to create a separate branch instead of stashing them indefinitely. Overuse of stash can lead to work being forgotten.

Git Stash alternatives and complementary tools
Although `git stash` is incredibly useful, there are times when other Git features are better suited.

– git commit –amend: If your changes are small and relevant to your current commit, you should modify your last commit instead of stashing it.
– Git cherry-pick: To move individual commits to other branches.
-Feature branches:If you’re working on something long-term or experimental, it may make more sense to create a new branch instead of relying on stashes. This makes it easier to track your changes and collaborate with others.

git checkout -b feature/new-feature

By using a branch instead of a stash, you can make incremental commits, which is often the better method in collaborative environments.

Conclusion

git stash is an incredibly powerful tool for managing your development workflow. It allows you to pause your work, switch tasks, and come back later without having to deal with incomplete commits or lost work. Whether you’re dealing with interrupts, switching between branches, or simply cleaning up uncommitted changes, Git stash has you covered.

Let’s summarize the most important points:

• git stash” temporarily stores your unconfirmed changes and allows you to return to them when you’re ready.
• You can view, apply and delete stashes with a series of commands such as git stash list, git stash apply and git stash drop.
• Advanced features, such as hiding certain files or creating branches from stashes, allow you to customize git stash to your needs.
• If you name your stashes and manage them carefully, you can keep track of them.
• Don’t overdo it with the stash — when it’s time to create a feature branch or make a commit, just do it!

If you incorporate git stash into your daily development habits, you’ll soon find that it makes your workflow smoother, less stressful and more flexible. It’s one of those tools that, once mastered, will make you a much more efficient and agile developer.

Have fun programming! And don’t forget: stash responsibly!
