Is this possibe to squash a few first commits into one, together with merge commit? It's not possible to simply pass HEAD~4 to git rebase -i because it will take 4 commits back from the first parent of the merge commit.

Answer 1

git rebase -i HEAD~4 would work just fine, also if it's a far commit or you don't know how far it is, take the hash of the parent of the first commit you want to edit, or for me I take the hash and append a ^ for saying parent

git rebase -i hash^

I think ~ would work too

git rebase -i hash~

Then you can set the first commit as pick p or reword if you want to change it's message r and the remaining 3 as fixup f so it doesn't keep stopping asking you for a new commit message, it will stop in the middle for any conflicts, also expect that you will need to re-resolve any conflicts if you pass by a commit that created one.

Answer 2

try: git rebase -i HEAD^2~3

'^' sign is used to select 1 of the parents (in this case ^2 means select second parent, and then ~3 means 'go 3 commits back')
