# Stash all changes (default):
git stash

# Stash with a custom message:
git stash push -m "WIP: login feature"

# Stash only staged changes:
git stash --staged

# Stash including untracked files:
git stash -u

# Stash including ignored files:
git stash -a

# List all stashes:
git stash list

# Show details of a stash:
git stash show -p stash@{0}

# Reapply latest stash and drop it:
git stash pop

# Reapply stash but keep it in stack:
git stash apply stash@{2}

# Delete a stash entry:
git stash drop stash@{1}

# Clear all stashes:
git stash clear

• Description: The git stash temporarily saves (or “stashes”) your uncommitted changes (both staged and unstaged) so you can work on something else, then reapply them later.
• Usage: It saves changes into a stack, lets you switch branches or pull updates safely, and reapply them later.
• Think Tank: Think of it as putting your unfinished work into a drawer - safe, out of the way, but retrievable.

• Best Practices:
  • Always add a message (-m) to describe the stash for clarity.
  • Use git stash list regularly to avoid losing track of multiple stashes.
  • Prefer git stash pop when you’re done with the stash, so it doesn’t clutter the stack.
  • Use git stash branch if you realize stashed changes deserve their own branch.
  • Avoid stashing ignored files unless absolutely necessary.

How it works

• Working tree + index snapshot: git stash takes the current state of your working directory and staging area, saves it as a new entry in the stash stack, and reverts your working directory to match HEAD (clean state).
• Stash stack: Each stash is stored as a commit object in a hidden ref (refs/stash). You can have multiple stashes, managed like a stack (LIFO).
• Reapply later: You can bring back stashed changes with git stash apply or git stash pop.
