Working with github.com

github has disabled basic authentiction (username and password) and now requires login with OAuth access tokens.

https://github.com/settings/tokens

"Personal access tokens function like ordinary OAuth access tokens. They can be used instead of a password for Git over HTTPS, or can be used to authenticate to the API over Basic Authentication."

You use these tokens as normal password when logging in.

$ git clone https://github.com/magnuskkarlsson/DO180-apps.git

$ cd DO180-apps/

$ git status

Create local branch and pushing it to remote.

$ git checkout -b branch_delete

$ git push -u origin branch_delete
username for 'https://github.com': <"Username">
Password for 'https://you@github.com': <Your Personal Access Token>

$ git branch -a

Delete local branch and delete remote branch.

$ git checkout master

$ git branch -d branch_delete

$ git push origin --delete branch_delete

You cannot delete a file in git, you need to delete it ('git rm') and commit and push the delete.

$ touch FOO

$ git add FOO

$ git commit -m "added FOO"

$ git push -u origin master 

$ git rm FOO

$ git add .

$ git commit -m "deleted FOO"

$ git push -u origin master
