Git Stash Basics

What is Git Stash?

Git stash is a powerful feature that allows developers to temporarily save uncommitted changes without committing them to the repository. This is particularly useful when you need to switch branches or pull updates but aren't ready to commit your current work.

Key Concepts

When to Use Git Stash

Developers typically use git stash in scenarios such as:

• Switching branches with unsaved changes
• Pulling remote updates when local changes are incomplete
• Pausing current work to address urgent tasks

Stash Workflow

Basic Stash Commands

Practical Example

## Create some changes
echo "Temporary work" > temp.txt

## Stash the changes
git stash

## List stashes
git stash list

## Restore stashed changes
git stash pop

Best Practices

• Use descriptive messages when stashing
• Regularly clean up unused stashes
• Understand the difference between apply and pop

LabEx recommends mastering stash techniques to improve development workflow efficiency.

Removing Stashed Changes

Understanding Stash Removal

Removing stashed changes is an essential skill for maintaining a clean and organized Git workflow. There are multiple methods to remove stashes, each serving different purposes.

Stash Removal Methods

Dropping a Single Stash

## Drop the most recent stash
git stash drop

## Drop a specific stash by index
git stash drop stash@{n}

Clearing All Stashes

## Remove all stashes
git stash clear

Advanced Stash Removal Techniques

Selective Stash Removal

Stash Removal Strategies

Practical Considerations

• Always review stashes before removal
• Use git stash list to check existing stashes
• Be cautious when using git stash clear

LabEx recommends careful management of stashes to prevent accidental data loss.

Error Handling

## Check stash existence before removal
if [[ $(git stash list) ]]; then
    git stash drop
else
    echo "No stashes to remove"
fi

Stash Management Tips

Effective Stash Naming and Organization

Adding Descriptive Messages

## Create a stash with a descriptive message
git stash save "Implement user authentication feature"

Stash Naming Conventions

Advanced Stash Techniques

Partial Stashing

## Stash specific files
git stash push -m "Partial changes" path/to/file1 path/to/file2

## Interactive stash
git stash save -p

Stash Management Strategies

Stash Branching

## Create a branch from a stash
git stash branch new-feature-branch stash@{0}

Best Practices

• Regularly clean up unnecessary stashes
• Use meaningful stash descriptions
• Avoid using stash as a long-term storage solution

Stash Cleanup Script

#!/bin/bash
## Remove stashes older than 30 days
git stash list | grep "WIP" | while read -r stash; do
    stash_date=$(git log -1 --format="%ci" $stash)
    if [[ $(date -d "$stash_date" +%s) -lt $(date -d "30 days ago" +%s) ]]; then
        git stash drop $stash
    fi
done

LabEx recommends developing a systematic approach to stash management for improved workflow efficiency.

Error Prevention

• Always verify stash contents before dropping
• Use git stash show to preview stashed changes
• Maintain a consistent stash management strategy

Summary

Mastering Git stash management is crucial for maintaining an efficient development process. By understanding how to remove, clear, and strategically manage stashed changes, developers can optimize their Git workflow, reduce clutter, and maintain better control over their project's version history.
