Combine the first two commits of a Git repository?

May 20, 2022 by Tarik

Use git rebase -i --root
as of Git version 1.7.12.

In the interactive rebase file, change the second line of commit B to squash and leave the other lines at pick:

pick f4202da A
squash bea708e B
pick a8c6abc C

This will combine the two commits A and B to one commit AB.
