Fresh start

1. create a new repository that has the initial commit that you want

   mkdir foo; cd foo; git init; ...; git commit

2. set up a remote

   git remote add origin <url-of-remote>
   git branch --set-upstream master origin/master
   

3. push your new history

   `git push -f``

4. delete obsolete remote branches

   git push origin :deprecated-branch

Source

Rebasing

Just rebase

git fetch origin
git reset --hard origin/master

Rebase fork

1. Add the remote, call it "upstream":

   git remote add upstream https://github.com/whoever/whatever.git

2. Fetch all the branches of that remote into remote-tracking branches, such as upstream/master:

   git fetch upstream

3. Make sure that you're on your master branch:

   git checkout master

4. Rewrite your master branch so that any commits of yours that aren't already in upstream/master are replayed on top of that other branch:

   git rebase upstream/master

Securely store credentials

Option 1: libsecret

• Get libsecret and gnome-keyring (seahorse for GUI)
• git config --global credential.helper libsecret

Option 2: netrc

source

• Get gnupg
• Script: https://raw.githubusercontent.com/git/git/master/contrib/credential/netrc/git-credential-netrc
  • Arch: /usr/share/git/credential/netrc/git-credential-netrc
  • Ubuntu: /usr/share/doc/git/contrib/credential/netrc/git-credential-netrc
• Create a new file (preferably ~/.netrc):

  machine github.com
  protocol <http|https|ssh>
  login <username>
  password <password>
  

• Generate a new key (if there's none already): gpg --gen-key
• Encrypt the file: gpg -e -r <email> ~/.netrc
• git config --global credential.helper "netrc -f ~/.netrc -v"
  • git-credentials- prefix will be automatically prepended to form git-credentials-netrc
  • Can add -d for debugging
  • For more info, git-credentials-netrc --help
