This script allows you to update your location on MapMe.At using DNS. You will need to have an account on that site and set up a shortcode on the Account page.
Clone this repository then symlink mapme.at.sh into your path.
You must set your shortcode before you can use this script. This will then be stored in plaintext on your system:
mapme.at.sh shortcode [<shortcode>]
Once shortcode has been set you can update location using either a favourite label or a raw lat/lon, e.g.:
mapme.at.sh home
mapme.at.sh 56.493773 0.439453
If you have a USB GPS device you can get the latitude and longitude from there. Assuming the device is already set up and configured simply try something similar to the following:
mapme.at.sh /dev/tty.HOLUXGPSlim236-SPPslave-1
