Quickly add your github keys as authorized to your virtual server

As a software developer, I constantly work with a bunch of virtual environments used for testing. The first step I do — is switch from password ssh authorization to authorization by public key. AWS, for example, creates ec2 instances with unique preset access key. Let me share with you handy batch, that will add all of your github keys as authorized — it will allow you to simply login as `ssh user@yournewremoteserver` next session , rather than `ssh -i yourtemporaryaccesskeyforserver.pem user@yournewremoteserver`

Note: of course it is not suitable for production environments.

Batch

USERNAME=yourgithubusername
mkdir -p ~/.ssh
if ! [[ -f ~/.ssh/authorized_keys ]]; then
  echo "Creating new ~/.ssh/authorized_keys"
  touch ~/.ssh/authorized_keys
fi
keys=`curl https://api.github.com/users/$USERNAME/keys | grep -o -E "ssh-\w+\s+[^\"]+"`
for key in $keys; do
  echo $key
  grep -q "$key" ~/.ssh/authorized_keys || echo "$key" >> ~/.ssh/authorized_keys
done

Usage

Usually I run it as:

curl -L http://bit.ly/easytoremembershortcut | bash -s

This approach has already saved me a lot of time.
