  4. # Description:
  5. #   This script tries retrieving the list with available hosts from different hosts.
  6. #   If succesfull the script will place the host.txt file at ~/recieved/
  7. #   This script needs hostsToTxt.sh to be located at ~/scripts/ in order to function
  8. #   This scripts supposes you are using an ssh-agent
  9. #   If not this might also work but you will be typing your password a lot.
