🧹 Undoing Changes

Unstage a File

Remove a file from the staging area but keep its changes.

git reset filename

Unstage all staged files:

git reset

Discard Unstaged Changes

Old syntax:

git checkout -- filename

Newer syntax (recommended):

git restore filename

⚠️ This will permanently discard your changes for that file.

Amend Last Commit

Change the last commit’s message or add new staged changes to it.

git commit --amend

Tip: Only amend if you haven’t pushed the commit yet.

Temporarily Saving Work (Stash)

Save uncommitted changes for later without committing.

git stash             # Save local modifications
git stash apply       # Reapply most recent stash
git stash list        # View all stashes
git stash drop        # Delete most recent stash
