Have you ever been in the middle of working on a feature when suddenly you need to switch branches or pull the latest changes? You're not ready to commit your incomplete work, but you also can't switch branches with uncommitted changes. This is where Git stash becomes your lifesaver.
๐ฏ What You'll Learn: In this comprehensive guide, you'll discover:
- What Git stash is and why it's essential for development workflow
- How stashing compares to committing incomplete code
- Managing multiple stashes with names and references
- Advanced stash operations: apply vs pop, selective stashing
- Best practices for using stash in team collaboration
- Common pitfalls and how to avoid them
๐ค Understanding Git Stash: The Problem it Solves
Git stash is a powerful feature that temporarily stores your uncommitted changes, allowing you to switch contexts without losing your work or polluting your commit history with incomplete code.
Prerequisites
Before we dive into stashing, make sure you have:
- Git installed on your system
- Basic understanding of
git add
,git commit
, andgit status
- A Git repository to practice with
- Understanding of branches and working directory concepts
Why Stash Instead of Commit?
Many beginners wonder: "Why not just commit the incomplete work?" Here's why stashing is the better choice:
Aspect | Git Stash | Incomplete Commit |
---|---|---|
History Impact | No impact on commit history | Clutters commit history |
Code Quality | Encourages complete, tested commits | May break builds for other team members |
Team Collaboration | Keeps shared branches clean | Can cause issues when others pull changes |
Flexibility | Easy to discard if not needed | Requires commit history rewriting |
๐ Setting Up Our Practice Scenario
Let's start with a practical scenario to understand Git stash. We'll begin by examining our repository state and making some changes.
Checking Repository Status
ls -ahl
Example Output:
total 20K
drwxr-xr-x. 3 centos9 centos9 105 Sep 25 19:08 .
drwxr-xr-x. 3 centos9 centos9 23 Sep 24 13:21 ..
-rw-r--r--. 1 centos9 centos9 15 Sep 24 13:50 fifth.txt
-rw-r--r--. 1 centos9 centos9 23 Sep 24 13:21 first.txt
-rw-r--r--. 1 centos9 centos9 12 Sep 25 19:08 fourth.txt
drwxr-xr-x. 8 centos9 centos9 183 Sep 25 19:08 .git
-rw-r--r--. 1 centos9 centos9 36 Sep 24 13:36 second.txt
-rw-r--r--. 1 centos9 centos9 17 Sep 24 13:33 third.txt
Understanding the listing:
- Five text files in our repository
.git
directory contains all Git metadata- File timestamps show when they were last modified
Examining File Contents
cat fourth.txt
Example Output:
new changes
This shows our current file content before we make modifications.
๐ Your First Stash: Basic Operations
Now let's create a scenario where stashing becomes necessary by making some changes and then needing to switch contexts.
Making Uncommitted Changes
Let's add some content to our file:
cat <<EOF >> fourth.txt
second line
third line
EOF
What this command does:
cat <<EOF >> fourth.txt
appends multiple lines to the file>>
means append (don't overwrite)- Everything between the two
EOF
markers gets added to the file
Verifying Our Changes
cat fourth.txt
Example Output:
new changes
second line
third line
File status: We've successfully added two new lines to the file.
Checking Git Status
git status
Example Output:
On branch master
Changes not staged for commit:
(use "git add <file>..." to update what will be committed)
(use "git restore <file>..." to discard changes in working directory)
modified: fourth.txt
no changes added to commit (use "git add" and/or "git commit -a")
Understanding Git's message:
On branch master
: We're currently on the master branchChanges not staged for commit
: Git detected file modificationsmodified: fourth.txt
: The specific file that changed- Git provides helpful suggestions for next steps
๐พ Creating Your First Stash
Now comes the magic moment - let's stash our changes temporarily.
Basic Stash Command
git stash
Example Output:
Saved working directory and index state WIP on master: e3bd41e Merge branch 'dev'
Understanding the stash output:
Saved working directory and index state
: Git saved all uncommitted changesWIP on master
: "Work In Progress" on the master branche3bd41e
: The commit hash where the stash was createdMerge branch 'dev'
: The commit message of the current HEAD
Verifying the Stash Worked
git status
Example Output:
On branch master
nothing to commit, working tree clean
What happened:
- Working directory is now clean (no uncommitted changes)
- All modifications were temporarily saved to the stash
- We can now safely switch branches or pull updates
Checking File Contents After Stash
cat fourth.txt
Example Output:
new changes
Important observation: The file content reverted to the last committed state. Our added lines are safely stored in the stash, not lost!
๐ Managing Your Stash Stack
Git stash works like a stack (Last In, First Out). Let's learn how to view and manage multiple stashes.
Viewing Your Stash List
git stash list
Example Output:
stash@{0}: WIP on master: e3bd41e Merge branch 'dev'
Understanding stash references:
stash@{0}
: The most recent stash (index 0)WIP on master
: Automatic description of the stashe3bd41e
: The commit hash where stash was created
Retrieving Your Stashed Changes
Using git stash pop
git stash pop
Example Output:
On branch master
Changes not staged for commit:
(use "git add <file>..." to update what will be committed)
(use "git restore <file>..." to discard changes in working directory)
modified: fourth.txt
no changes added to commit (use "git add" and/or "git commit -a")
Dropped refs/stash@{0} (33e8ffb8286507344df010dd576bab6bced763a0)
Key behaviors of git stash pop
:
- Restores your changes to the working directory
- Removes the stash from the stash stack (it's deleted)
- Shows the stash reference that was dropped
Verifying Changes Were Restored
cat fourth.txt
Example Output:
new changes
second line
third line
Perfect! Our changes are back exactly as we left them.
Confirming Stash Was Removed
git stash list
Expected Output: (empty - no output)
This confirms: The stash stack is now empty because pop
removed the stash after applying it.
๐ท๏ธ Working with Named Stashes
For better organization, especially when working with multiple stashes, you can give them descriptive names.
Creating a Named Stash
Let's create another scenario with multiple files:
git status
Current Status:
On branch master
Changes not staged for commit:
(use "git add <file>..." to update what will be committed)
(use "git restore <file>..." to discard changes in working directory)
modified: fourth.txt
no changes added to commit (use "git add" and/or "git commit -a")
We still have our changes from before. Let's stash them with a name:
git stash save "first"
Example Output:
Saved working directory and index state On master: first
Benefits of named stashes:
save "first"
: Creates a stash with a custom message- Makes it easier to identify specific stashes later
- Essential when managing multiple stashes simultaneously
Creating Multiple Stashes
Let's make changes to another file:
cat third.txt
Current Content:
this is new file
Let's add some content:
cat <<EOF >> third.txt
2nd line
3rd line
EOF
Checking the New Changes
cat third.txt
Example Output:
this is new file
2nd line
3rd line
git status
Example Output:
On branch master
Changes not staged for commit:
(use "git add <file>..." to update what will be committed)
(use "git restore <file>..." to discard changes in working directory)
modified: third.txt
no changes added to commit (use "git add" and/or "git commit -a")
Now let's stash these changes too:
git stash save "second"
Example Output:
Saved working directory and index state On master: second
Viewing Multiple Stashes
git stash list
Example Output:
stash@{0}: On master: second
stash@{1}: On master: first
Understanding the stack order:
stash@{0}
: Most recent stash ("second")stash@{1}
: Previous stash ("first")- The numbers increase as stashes get older
๐ฏ Advanced Stash Operations
Let's explore more sophisticated stash operations that give you greater control over your saved work.
Using git stash apply
vs git stash pop
Applying a Specific Stash (Keep in Stack)
git stash apply stash@{1}
Example Output:
On branch master
Changes not staged for commit:
(use "git add <file>..." to update what will be committed)
(use "git restore <file>..." to discard changes in working directory)
modified: fourth.txt
no changes added to commit (use "git add" and/or "git commit -a")
Key difference with apply
:
- Restores the changes to your working directory
- Keeps the stash in the stack (doesn't delete it)
- Allows you to reuse the same stash multiple times
Verifying Changes Were Applied
cat fourth.txt
Example Output:
new changes
second line
third line
Checking Stash List After Apply
git stash list
Example Output:
stash@{0}: On master: second
stash@{1}: On master: first
Important: Both stashes are still there! apply
doesn't remove stashes from the stack.
Stashing Current Changes Again
Since we now have uncommitted changes again, let's stash them:
git stash
Example Output:
Saved working directory and index state WIP on master: e3bd41e Merge branch 'dev'
Now we have three stashes:
git stash list
Example Output:
stash@{0}: WIP on master: e3bd41e Merge branch 'dev'
stash@{1}: On master: second
stash@{2}: On master: first
Notice: All previous stashes shifted down by one index number.
๐ Working with Multiple Stashes Simultaneously
Let's explore a real-world scenario where you might need to combine changes from multiple stashes.
Applying Multiple Stashes
Apply the Oldest Stash First
git stash apply stash@{2}
Example Output:
On branch master
Changes not staged for commit:
(use "git add <file>..." to update what will be committed)
(use "git restore <file>..." to discard changes in working directory)
modified: fourth.txt
no changes added to commit (use "git add" and/or "git commit -a")
cat fourth.txt
Example Output:
new changes
second line
third line
Apply the Second Stash (Different File)
git stash apply stash@{1}
Example Output:
On branch master
Changes not staged for commit:
(use "git add <file>..." to update what will be committed)
(use "git restore <file>..." to discard changes in working directory)
modified: fourth.txt
modified: third.txt
no changes added to commit (use "git add" and/or "git commit -a")
Checking Combined Changes
git status
Example Output:
On branch master
Changes not staged for commit:
(use "git add <file>..." to update what will be committed)
(use "git restore <file>..." to discard changes in working directory)
modified: fourth.txt
modified: third.txt
no changes added to commit (use "git add" and/or "git commit -a")
Verification of both files:
cat fourth.txt
new changes
second line
third line
cat third.txt
this is new file
2nd line
3rd line
Success! We now have changes from multiple stashes active simultaneously in our working directory.
๐งน Cleaning Up Your Stash Stack
After working with stashes, it's important to clean up to avoid confusion.
Viewing All Stashes Before Cleanup
git stash list
Example Output:
stash@{0}: WIP on master: e3bd41e Merge branch 'dev'
stash@{1}: On master: second
stash@{2}: On master: first
Clearing All Stashes at Once
git stash clear
What this command does:
- Removes all stashes from the stack
- Cannot be undone - use with caution
- Useful for cleaning up when stashes are no longer needed
Verifying Stashes Were Cleared
git stash list
Expected Output: (empty - no output)
Confirmation: All stashes have been removed from the stack.

๐จ Common Scenarios and Best Practices
Team Collaboration Scenarios
๐ก Team Workflow: Stashing is essential when working in teams to maintain clean, stable branches.
Scenario 1: Urgent Bug Fix Needed
# You're working on a feature
echo "incomplete feature code" >> feature.txt
git status # Shows uncommitted changes
# Urgent bug fix needed - stash your work
git stash save "incomplete feature work"
# Switch to main branch for bug fix
git checkout main
# Fix the bug, commit, and push
# Return to your feature branch
git checkout feature-branch
git stash pop # Resume your work
Scenario 2: Need to Pull Latest Changes
# You have local changes
git status # Shows modified files
# Can't pull with uncommitted changes
git pull origin main # This might fail
# Solution: stash first
git stash
git pull origin main # Now this works
git stash pop # Apply your changes back
Advanced Stashing Techniques
Stashing Only Specific Files
# Stash only tracked files (ignore untracked)
git stash --keep-index
# Stash everything including untracked files
git stash --include-untracked
# Interactive stashing (choose what to stash)
git stash --patch
Stashing with Better Messages
# Descriptive messages for team clarity
git stash save "WIP: user authentication module - password validation pending"
git stash save "TEMP: debugging payment gateway integration"
git stash save "FEATURE: half-implemented search functionality"
โ ๏ธ Common Pitfalls and How to Avoid Them
Pitfall 1: Forgetting About Stashed Work
โ ๏ธ Problem: Developers forget they have stashed work and it gets lost in the stack.
Solution:
- Use descriptive stash messages
- Regularly check
git stash list
- Clean up old stashes that are no longer needed
Pitfall 2: Stash Conflicts
When applying a stash, you might encounter conflicts if the base code has changed:
git stash pop
# Auto-merging file.txt
# CONFLICT (content): Merge conflict in file.txt
Resolution steps:
- Edit the conflicted files to resolve conflicts
- Add the resolved files:
git add file.txt
- The stash is automatically dropped after conflict resolution
Pitfall 3: Accidentally Clearing All Stashes
๐จ Important: git stash clear
cannot be undone. Always verify what stashes you have before clearing:
# Safe approach
git stash list # Review all stashes first
# If you see important work, apply it first
git stash clear # Only after confirming
๐ฏ Key Takeaways
โ Remember These Points
- Stash Before Context Switching: Always stash uncommitted work before switching branches or pulling updates
- Use Descriptive Messages: Named stashes (
git stash save "message"
) are easier to manage than default ones - Understand Apply vs Pop: Use
apply
when you might need the stash again,pop
when you're done with it - Stack Management: Stashes work as a stack (LIFO) - newest stash is
stash@{0}
- Team Collaboration: Stashing keeps shared branches clean by avoiding incomplete commits
