Script to clone all repositories of specified organization

github_org_clone_all.rb

#!/usr/bin/env ruby

# gem i github_api

## Setting -> Applications -> Personal Access Tokens -> Generate new token
# Selected scopes:
# * repo
# * public_repo
# * repo:status
# * read:org
## Generate token -> copy token and paste to "oauth_token"

oauth_token = "...."
org_name = 'yourcompany'

exists = Dir.glob('*')

require 'github_api'
github = Github.new(basic_auth: oauth_token)

pagenum = 1
list = []
while page = github.repos.list(org: org_name, page: pagenum, per_page: 100)
  break if page.size < 1
  list += page.to_a
  pagenum += 1
end

dup = list.select{|repo| exists.include?(repo["name"]) }
puts "skipping #{dup.size} repositories which already exists.\n"

list = list.select{|repo| ! exists.include?(repo["name"]) }
puts "cloning #{list.size} repositories.\n"

list.each do |repo|
  system "git clone #{repo["ssh_url"]}"
  sleep 5
end

Why sleep 5?

It's a magic number. I know how engineers in github.com thinks :)
