Git commands worth memorising

git status what is actually changed right now git diff what changed, line by line, unstaged git add -p stage selected chunks, not whole files git commit -m "message" save a checkpoint git switch -c feat/thing new branch off where you are git switch main back to the trunk git restore <file> throw away uncommitted changes to one file git log --oneline -10 the last ten commits, one line each The two that save you: git stash park everything, do something else, then git stash pop to get it back git revert <commit> undo a commit by making a new one, which is safe on shared branches The one to be careful with: git reset --hard discards uncommitted work permanently. There is no undo.
