🎯 Goal: Learn how to save your current changes using git stash and then restore them using git stash pop.

📋 What You'll Learn

Create a new file with some content

Use git stash to save changes

Use git stash pop to restore changes

Verify the restored changes

💡 Why This Matters

🌍 Real World

Developers often need to pause work on one task and switch to another without committing incomplete changes. Using git stash helps keep the working directory clean.

💼 Career

Knowing how to use git stash and git stash pop is essential for managing code changes efficiently in collaborative software development environments.

1

Create a new file with changes

Create a new file called example.txt and add the line Hello, Git! to it.

Git

# Create a new file named example.txt and add the text 'Hello, Git!'
# Your code here

Hint

Use the echo command to write text to a file.

2

Save changes using git stash

Run the command git stash to save your current changes temporarily.

Git

echo "Hello, Git!" > example.txt
# Run 'git stash' to save changes
# Your code here

Hint

Simply type git stash to save your changes.

3

Restore changes using git stash pop

Run the command git stash pop to restore the saved changes back to your working directory.

Git

git stash
# Run 'git stash pop' to restore changes
# Your code here

Hint

Use git stash pop to apply and remove the latest stash.

4

Verify restored changes

Run cat example.txt to display the contents of example.txt and verify it shows Hello, Git!.

Git

git stash pop
# Run 'cat example.txt' to show the file content
# Your code here

Hint

Use cat example.txt to see the file content.

Practice

1. What does the git stash pop command do in Git?

easy

A. It restores the most recent stashed changes and removes them from the stash list.

B. It permanently deletes all stashes without restoring changes.

C. It creates a new stash with the current changes.

D. It lists all the stashes without applying any changes.

Solution

1. Step 1: Understand the purpose of git stash pop

   This command is used to bring back the most recent saved changes from the stash and apply them to the working directory.

2. Step 2: Recognize the effect on the stash list

   After applying the changes, it removes that stash entry from the stash list, unlike git stash apply which keeps it.

3. Final Answer:

   It restores the most recent stashed changes and removes them from the stash list. -> Option A

4. Quick Check:

   git stash pop = restore + remove stash [OK]

Hint: Pop restores and deletes stash; apply restores only [OK]

Common Mistakes:

• Confusing pop with apply
• Thinking pop deletes all stashes
• Believing pop creates a new stash

2. Which of the following is the correct syntax to restore stashed changes using git stash pop?

easy

A. git stash apply pop

B. git pop stash

C. git stash restore

D. git stash pop stash@{1}

Solution

1. Step 1: Identify correct command structure

   The correct command to pop a specific stash is git stash pop followed by the stash reference, e.g., stash@{1}.

2. Step 2: Eliminate incorrect options

   Options B, C, and D are invalid Git commands or incorrect syntax.

3. Final Answer:

   git stash pop stash@{1} -> Option D

4. Quick Check:

   Pop syntax = git stash pop [stash_ref] [OK]

Hint: Use stash@{n} to pop specific stash [OK]

Common Mistakes:

• Using 'git pop stash' which is invalid
• Confusing 'apply' and 'pop' syntax
• Using 'git stash restore' which doesn't exist

3. Given the following commands executed in order:

git stash save "work in progress"
git stash pop

What will be the output or effect after git stash pop?

medium

A. The stash list remains unchanged and changes are not restored.

B. The saved changes are restored to the working directory and the stash is removed.

C. An error occurs because stash pop requires a stash reference.

D. The changes are restored but the stash remains in the list.

Solution

1. Step 1: Understand git stash save

   This command saves current changes to a new stash with the message "work in progress".

2. Step 2: Understand git stash pop without arguments

   By default, it restores the most recent stash and removes it from the stash list.

3. Final Answer:

   The saved changes are restored to the working directory and the stash is removed. -> Option B

4. Quick Check:

   Pop restores + deletes latest stash [OK]

Hint: Pop without args restores latest stash [OK]

Common Mistakes:

• Thinking pop needs stash reference always
• Believing stash remains after pop
• Expecting error on pop without args

4. You ran git stash pop but got a conflict error. What is the best way to fix this?

medium

A. Ignore the conflicts and continue working without fixing.

B. Run git stash pop again immediately to overwrite conflicts.

C. Manually resolve the conflicts in files, then stage and commit the changes.

D. Delete the stash manually and reset the branch to discard changes.

Solution

1. Step 1: Understand conflict after stash pop

   Conflicts mean changes from stash and current files clash and must be fixed manually.

2. Step 2: Resolve conflicts properly

   Open conflicted files, fix differences, then stage and commit to save resolved state.

3. Final Answer:

   Manually resolve the conflicts in files, then stage and commit the changes. -> Option C

4. Quick Check:

   Fix conflicts manually after stash pop [OK]

Hint: Resolve conflicts manually, then stage and commit [OK]

Common Mistakes:

• Rerunning stash pop causing more conflicts
• Deleting stash without restoring changes
• Ignoring conflicts and losing work

5. You have two stashes saved: stash@{0} and stash@{1}. You want to restore stash@{1} but keep stash@{1} intact. Which command should you use?

hard

A. git stash apply stash@{1}

B. git stash pop stash@{0}

C. git stash pop stash@{1}

D. git stash drop stash@{1}

Solution

1. Step 1: Understand difference between pop and apply

   git stash pop restores and removes the stash entry; git stash apply restores but keeps the stash.

2. Step 2: Choose command to restore stash@{1} without removing it

   Use git stash apply stash@{1} to restore changes but keep stash@{1} in the list.

3. Final Answer:

   git stash apply stash@{1} -> Option A

4. Quick Check:

   Apply restores stash without deleting it [OK]

Hint: Use apply to restore stash without deleting it [OK]

Common Mistakes:

• Using pop which deletes the stash
• Dropping stash instead of restoring
• Applying wrong stash reference
