Linux CLI Shell Login script that displays various system and user statistics after sign-in validation. Additionally a call to a thin RSS webpage gives basic two day weather info within the same data stream. This weather can be set to display the weather at the server location as default with option for individual users setting a dot file in $HOME to provide their own personal weather forcast. Also, this user configurable dot file can store several variables to toggle off a few info lines for a more compact view.
NOTE: Requires installation of curl
