Fetch all forks of github repository. Uses gems 'github_api' and 'hub'

github-fetch-forks

#!/usr/bin/env ruby
 
# Install gems:
# gem install github_api
# gem install hub
#
# Then run script in github repo
require 'github_api'
 
g = Github.new
 
path = `git remote show -n origin | grep Fetch | cut -d: -f2-`
raise "You're not in a git repo with an origin remote" if path.empty?
 
username, repo = path.split("/")[0].split(":")[1], path.split("/")[1].split(".")[0]
 
forks = g.repos.forks.list username, repo
usernames = forks.map(&:owner).map(&:login)
 
usernames.each do |username|
  puts "hub fetch #{username}"
  `hub fetch #{username}`
end

Try to get correct path, username and repo.

path = git remote show -n origin | grep Fetch | cut -d: -f2-
username, repo = path.split("/")[0].split(":")[1], path.split("/")[1].split(".")[0]
