docker-FindGitHubEmail

FindGitHubEmail - a simple script to find the email address of any GitHub user. This is a docker image that eases setup.

About FindGitHubEmail

From the official readme:

It's a well-known fact (or at least it should be) that everything you push to a public GitHub repository is public. This includes a lot of information other than just source files. Since both Git and GitHub require you to provide an email address, it should be no surprise that this information is public as well. FindGitHubEmail (catchy title, I know) is a simple script that queries the GitHub API and guesses a given user's email address based on their public activity. The script is a bit of a hack; sorry if your eyes are bleeding.

FindGitHubEmail makes it easy to get in contact with open source developers. Please use it for good, not evil.

Install

This docker image is available as a trusted build on the docker index, so using it is as simple as running:

$ docker run clue/findgithubemail

Running this command for the first time will download the image automatically. Further runs will be immediate, as the image will be cached locally.

To further ease running, it's recommended to set up a much shorter alias so that you can easily execute it as just github-email:

$ alias github-email='docker run -it --rm clue/findgithubemail'

This will create a temporary alias. In order to make it persist reboots, you can append this exact line to your ~/.bashrc (or similar) like this:

$ alias github-email >> ~/.bashrc

Usage

Once installed, running FindGitHubEmail is as simple as invoking it like this:

$ github-email clue

From the official usage help:

The above will return the best guess of the email based on the user's event log. If you're not looking for me, replace clue with another GitHub user.

Print all emails in the user's event log:

$ github-email -e clue

Or cross-check the discovered emails with the user's Gravatar ID:

$ github-email -g clue

Or if you're unsure and need the usage info:

$ github-email
