get name of a branch from which a (current) branch is created in git

Question

Lets say I created a branch called feature1 from develop branch.

Also, I created a issue123 branch from feature1 branch.

Now I want to know that feature1 is created from develop branch, and similarly issue123 branch is created from develop branch.

How can I do that?

Any help is very much appreciated. Thanks.

Answer 1

Not Exactly what you want, but some close solutions to it are ..

git show-branch
git show-branch --all

And,

git log --all --graph --decorate --oneline --simplify-by-decoration
