Steps 10&11 for cleaning and updating remote and local repos about yii-dev-tool HOT 1 OPEN

About branch deleting
I ask for git branch --help and see the text:

With a -d or -D option, <branchname> will be deleted. You may specify
more than one branch for deletion. If the branch currently has a reflog
then the reflog will also be deleted.

...

-d, --delete
Delete a branch. The branch must be fully merged in its upstream
branch, or in HEAD if no upstream was set with --track or --set-upstream-to.

-D
Shortcut for --delete --force.

So you get The branch 'branch-name-to-be-deleted' is not fully merged. reasonably.
And the solution for you is git branch -D branch-name-to-be-deleted, as git said to you.

About sync

Usual commands to sync repos:

• git fetch
• git pull

If you want to get changes from main branch into yours, you can do git pull origin main-remote-branch-name:main-local-branch-name after the remote repo had been configured.
