How to properly update a branch in Git?

Question

git

Hello.
I recently found out that git rebase changes commits, which is why you can’t do a rebase if a push was made to a public repo.
There was a question, but how to update the branch?
If I am working on branch A and I understand that I need to make a fix to the project. I create a new branch from say dev branch, make a fix. And I send this fix to the public repository. How, in this case, to update branch A so that it contains a new fix?

Answer 1

if you do a rebase, for example, 5 commits and try to merge it into the master branch, then you will have 5 identical commits (by changes)
, that is, if you have already pushed the fixes, the next commits go
if you work with a small team, then you can agree to rebase in branches with features, but after merging it into the master, it’s still better not to rewrite the commit history
