simple helper for copying my ssh keys to new machines. ((useful if you're trying to deal with 10 pi's and reformat them almost every day))

scpk

#!/bin/bash

# simple script to get a ssh-key on a remote machine
# assumes you're using id_rsa as your identity file which is the default from `ssh-keygen`


# usage: ./scpk <[user@]host>
# ie: `./scpk pi@raspberrypi` or `./scpk raspberrypi`

# default to 'raspberrypi' if no host is provided
TARGET_HOST=${1:-"raspberrypi"}

ssh $TARGET_HOST "echo `cat $HOME/.ssh/id_rsa.pub` >> ~/.ssh/authorized_keys"
