remap prefix to Control + a

	#!/usr/bin/env bash

	# Check we've got command line arguments
	if [ -z "$*" ] ; then
	echo "Need to specify ssh options"
	exit 1
	fi

	# Start trying and retrying
	((count = 100))

	#!/bin/bash

	mkdir -p ~/.ssh

	# generate new personal ed25519 ssh keys
	ssh-keygen -o -a 100 -t ed25519 -f ~/.ssh/id_ed25519 -C "rob thijssen <[email protected]>"
	ssh-keygen -o -a 100 -t ed25519 -f ~/.ssh/id_robtn -C "rob thijssen <[email protected]>"

	# generate new host cert authority (host_ca) ed25519 ssh key
	# used for signing host keys and creating host certs

	#!/bin/bash -x
