        email = your@email.net
[color]
        ui = true
[core]
        editor = vim
[fetch]
        prune = true
[merge]
        tool = meld
[mergetool]
        keepBackup = false
[pull]
        rebase = false
[status]
        showUntrackedFiles = all
Or using shell commands e.g.
git config --global fetch.prune true
