Instantly share code, notes, and snippets.

A quick way to find all the forks of a particular github project.
#!/usr/bin/env python
import os
import urllib2
import json
import subprocess
github_cmd="git config --get remote.github.url".split(" ")
origin_cmd="git config --get remote.origin.url".split(" ")
# we want to determine the user / repository name
# my convention is that my own projects use 'github' as the remote
# origin when I created it. And, obviously, a clone will use 'origin'.
# so try them each
github = subprocess.check_output(github_cmd).strip()
user, repo = github.split('/')[-2:]
user = user.lstrip('')
repo = repo.rstrip('.git')
except subprocess.CalledProcessError:
pass # ok, so no remote called 'github', let's try origin
if user is None and repo is None:
origin = subprocess.check_output(origin_cmd).strip()
user, repo = origin.split('/')[-2:]
repo = repo.rstrip('.git')
except subprocess.CalledProcessError:
print("Could not determine user or repo.")
resp = urllib2.urlopen(github_url % (user, repo))
if resp.code == 200:
content =
data = json.loads(content)
for remote in data:
remote_add_cmd="git remote add %s %s" % (remote['owner']['login'], remote['clone_url'])
print remote_add_cmd" "))
fetch_all_cmd="git fetch --all"
print fetch_all_cmd" "))

when I clone this repo - it fails. couldn't work it out I'm afraid.

but this url definitely works

Github forks api returns this header, so the script does not get all results

Link:; rel="next",; rel="last"


I've added a module find_forks based on this gist with python 3 support and it gets all forks.
