Why stashing saves work temporarily in Git - Visual Breakdown

Process Flow - Why stashing saves work temporarily

Start with changes in working directory

↓

Run git stash command

↓

Changes saved in stash stack

↓

Working directory cleaned

↓

Later: run git stash apply/pop

↓

Changes restored to working directory

This flow shows how git stash temporarily saves your current changes, cleans your working directory, and later restores those changes when you need them.

Execution Sample

Git

git status
# shows modified files

git stash
# saves changes and cleans working directory

git status
# shows clean working directory

git stash apply
# restores saved changes

This sequence saves your current changes temporarily, cleans your workspace, and then restores the changes when you apply the stash.

Process Table

Step	Command	Working Directory State	Stash Stack State	Output/Result
1	git status	Modified files present	Empty	Lists modified files
2	git stash	Clean (no changes)	One stash entry with saved changes	Saved working changes to stash
3	git status	Clean (no changes)	One stash entry	No modified files shown
4	git stash apply	Modified files restored	One stash entry	Restored changes from stash
5	git status	Modified files present	One stash entry	Lists restored modified files

💡 After applying stash, changes are restored but stash entry remains until dropped or popped.

Status Tracker

Variable	Start	After Step 2	After Step 4	Final
Working Directory	Has uncommitted changes	Clean (no changes)	Has uncommitted changes restored	Has uncommitted changes restored
Stash Stack	Empty	One stash entry	One stash entry	One stash entry

Key Moments - 3 Insights

Why does git stash clean the working directory after saving changes?

Because git stash saves your changes safely in the stash stack, it can then remove them from your working directory so you can work on a clean state. See execution_table step 2 where working directory becomes clean.

Does git stash delete your changes permanently?

No, it only saves them temporarily in the stash stack. You can restore them later with git stash apply or pop. See execution_table steps 2 and 4.

What happens to the stash entry after git stash apply?

The stash entry remains until you explicitly drop it or use git stash pop which applies and removes it. See execution_table step 5 where stash stack still has one entry.

Visual Quiz - 3 Questions

Look at the execution table, what is the state of the working directory immediately after running 'git stash'?

A Clean with no changes

B Still has modified files

C Contains untracked files only

D Contains staged changes only

💡 Hint

Check execution_table row 2 under 'Working Directory State'

At which step does the stash stack first contain an entry?

A Step 1

B Step 2

C Step 3

D Step 4

💡 Hint

Look at execution_table rows and see when stash stack changes from empty to one entry

If you run 'git stash pop' instead of 'git stash apply' at step 4, what would change in the stash stack?

A Stash stack would still have one entry

B Stash stack would have two entries

C Stash stack would be empty after pop

D Stash stack would be unchanged

💡 Hint

Recall that 'git stash pop' applies and removes the stash entry

Concept Snapshot

git stash saves your current uncommitted changes temporarily.
It cleans your working directory so you can work cleanly.
Changes are stored in a stash stack until you apply or pop them.
Use 'git stash apply' to restore changes without removing stash.
Use 'git stash pop' to restore and remove stash entry.
Stash helps switch tasks without losing work.

Full Transcript

Git stash temporarily saves your current changes in a special storage called the stash stack. When you run 'git stash', your changes are saved and your working directory is cleaned so you can work on something else without losing your work. Later, you can restore your saved changes using 'git stash apply' which keeps the stash entry, or 'git stash pop' which restores and removes the stash entry. This lets you switch tasks easily without committing unfinished work.
