This does nothing too useful and doesn't do anything you couldn't do with some bash-foo. It downloads all repositories under a github organisation with one command.
It was a fun way to revise some Golang and pass time while waiting for a long download to finish.
Have fun on your first day at work.
go get -u github.com/kasisnu/gh-recurse
ex,
gh-recurse google # Download all repositories under the Google Github organisation
gh-recurse google --type forks # Download only things that Google forked
gh-recurse google --type private # Download only repositories internal to Google(requires privileged access token)
gh-recurse google --type private --dry-run # Show me what you would download
