Cloning

1
$ git clone git@github.com:marcofranssen/grunt-dotnet-codecoverage.git

Get all remote branches as local tracking branches except master and HEAD since you already got those with the clone command.

1
$ for branch in 'git branch -a | grep remotes/origin | grep -v HEAD | grep -v master'; do git branch --track ${branch##remotes/origin/} $branch; done

Most probably you also want to fetch and pull the remote tracking branches

1
2
$ git fetch --all
$ git pull --all

Recovering your local branch from a force push

This will remove all commits previously on master and all commits done by yourself which are not yet pushed.

1
2
$ git fetch
$ git reset origin/master --hard

To preserve your own changes and commit them again do the following.

1
2
$ git fetch
$ git reset origin/master --soft

This will move all changes to your working directory, so you can commit them again manually.
You can also do an interactive rebase. In this case you have to pick the commits you want to keep.

1
2
$ git fetch
$ git rebase -i origin/master

Please note if you keep one of the commits you kept behind was one of the commits removed with the force push, that commit will again be reintroduced at the remote.
