I made these Snippets for Inventory to SSH configuration conversion. USE WITH CAUTION the default `StrictHostKeyChecking no` is weakening security by ignoring Host ssh key changes!

build_ssh_config.sh

#!/bin/bash
cat ~/.ssh/config.d/*

echo "#################################################"
echo "# This will be your new ssh config, is this ok? #"
echo "#################################################"
read -p "Build Config! (y/n)?" choice
case "$choice" in
  y|Y ) echo "yes" && cat ~/.ssh/config.d/* > ~/.ssh/config ;;
  n|N ) echo "no";;
  * ) echo "invalid";;
