I'm using Github API to ge the list of public repos , just change type=private or all . The results are paginated ,by 30 by default, you can specify further pages with the ?page parameter : curl -u "$USER:$PASSWORD" -H 'X-GitHub-OTP: $TWOFACTORCODE' https://api.github.com/orgs/magnetic/repos\?type\=public\&page\=1 | jq '.[] | .full_name '

Clone all curl -s https://api.github.com/orgs/twitter/repos?per_page=200 | ruby -rubygems -e 'require "json"; JSON.load(STDIN.read).each { |repo| %x[git clone #{repo["ssh_url"]} ]}'
