# WARNING: This will LOCK ALL PUBLIC REPOSITORIES ON YOUR GITHUB ACCOUNT

# dependencies hub and jq
# - hub: hub.github.com

#
# A better alternative would be to pipe the repos into a temporary file:
# $ hub api --paginate users/amingilani/repos | jq -r '.[]."full_name"' > repos.txt
# Then manually remove your active repositories
# And archive the remaining:
# $ cat repos.txt | xargs -I {} -n 1 hub api -X PATCH -F archived=true /repos/{}

# Anyways, to archive all public repositories in your GitHub account:
