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"]} ]}'

To download all repositories from my user account for backup purposes, I had to modify the command like this:

curl -s https://api.github.com/users/<USERNAME>/repos?per_page=100 | ruby -rjson -e 'JSON.load(STDIN.read).each {|repo| %x[git clone #{repo["clone_url"]} ]}'

per_page in @fonic's comment is crucial here if you're downloading lots of repos - which you presumably are since you want to automate it ;)
see also https://stackoverflow.com/questions/27331849/github-api-v3-doesnt-show-all-user-repositories

curl -s https://api.github.com/orgs/[ORGANIZATION]/repos | grep -e 'clone_url*' | cut -d \" -f 4 | xargs -L1 git clone

For enterprise github:

curl -H "Authorization: token [YourPersonalToken]" -s https://[YourCompanyHostname]/api/v3/orgs/[YourOrganisation]/repos?per_page=200 | ruby -rubygems -e 'require "json"; JSON.load(STDIN.read).each { |repo| %x[git clone #{repo["ssh_url"]} ]}'

You can generate your personal token at Settings/Developer Settings or directly to this url: https://[YourCompanyHostname]/settings/tokens (make sure you select the right scope repo/public_repo)

Thanks @ktiniatros

if you have go, it becomes easier:

curl -sS -H "Authorization: token $GITHUB_TOKEN" https://api.github.com/user/repos?per_page=200 \
	| jq -r '.[].svn_url' \
	| while read svn_url; \
	do go get -d "${svn_url##*://}"; done

Thank you @paravz, in your solution I love it.
Reminder we need have installed jq

ghorg is a cli that does this. It supports github, gitlab, and bitbucket.

After some searching and frustrations of my own not being able to do this easily, I built out a project that allows for public and private repo cloning of both personal and organization repos. Perfect for grabbing everything you'd need:

Looks awesome works like a charm thanks!

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"]} ]}'
