Can not rebase to first commit

I can not rebase to first commit.

This is how to reproduce:

kes@work ~/work/projects/general/Auth $ git tree
* 67857d5 (HEAD -> dev) asdf
* 1e99034 (local/dev) Initial commit
kes@work ~/work/projects/general/Auth $ git rebase -i --autostash --rebase-merges 1e99034^
fatal: invalid upstream '1e99034^'

git --version git version 2.30.0

-- Best regards, Eugen Konkov

Hi, Eugen

'1e99034^' means "the first parent of 1e99034". However, this is the root commit of your branch, so it has no parent. That's why rebase complained about '1e99034^' being invalid. To rebase this commit you can instead use the --root option.

Thanks, Matheus

Thank you for all.

I always thought that 1e99034^ means: including this commit

Thanks for help

(Unrelated to your question, but I assume that 'git tree' is an alias of 'git log --oneline --graph' by the looks of it).

Yes, this is because you're asking to rebase your branch onto the parent of 1e99034, which doesn't exist because 1e99034 is the "root" commit and therefore has no parents.

'git rebase' has a special option for exactly this case, which is '--root'. By replacing '1e99034^' with '--root', you should be able to do what you want.

Thanks, Taylor

See `git rebase --root` where the documentation says "This allows you to rebase the root commit(s) on a branch.".

The commit 1e99034 has no parent, so 1e99034^ errors out.

Try the `--root` option. That should do what you want.

This is because the first commit (1e99034) does not have a parent, so 1e99034^ cannot be resolved.

git rebase does however have an option for this: git rebase -i --root. That allows you to rebase the root commit.

Hope this helps, Kevin
