Git: how to create different unmerged states?

Question

When do different git status unmerged states occur, like added by us, added by them or both deleted?

I've tried to reproduce the latter by performing a merge where a file has been deleted in the current and merged-from branch, but I was not able to create this status.

Answer 1

You can get all three by renaming a file differently in each branch.

git init
touch foo
git add foo
git commit -m 'initial commit'
git checkout -b tmp
git mv foo X
git commit -m 'rename to X'
git checkout -
git mv foo Y
git commit -m 'rename to Y'
git merge tmp

Now you have all three states.

$ git status
# On branch master
# Unmerged paths:
#   (use "git add/rm ..." as appropriate to mark resolution)
#
#       added by them:      X
#       added by us:        Y
#       both deleted:       foo
#
no changes added to commit (use "git add" and/or "git commit -a")
