Clone all repos from a GitHub organization

Clone-All-Repos-GitHub-Organization.md

Publics repos

With Ruby 1.8 (default version on MacOS) :

sudo gem install json
curl -s https://api.github.com/orgs/[ORGANIZATION]/repos | ruby -rubygems -e 'require “json”; JSON.load(STDIN.read).each {|repo| %x[git clone #{repo["ssh_url"]} ]}'

With Ruby 1.9+, the json library is by default thus you just use :

curl -s https://api.github.com/orgs/[ORGANIZATION]/repos | ruby -rjson -e 'JSON.load(STDIN.read).each {|repo| %x[git clone #{repo["ssh_url"]} ]}'

---

Private repos

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

At Ruby 2.5 ubygems.rb was removed from Ruby, if you are using a higher version you should replace ruby -rubygems by ruby -rrubygems

The whole command for private repos would then be:
curl -u [[USERNAME]] -s https://api.github.com/orgs/[[ORGANIZATION]]/repos?per_page=200 | ruby -rrubygems -e 'require "json"; JSON.load(STDIN.read).each { |repo| %x[git clone #{repo["ssh_url"]} ]}'
