On of the most interesting things to do with linux is use the command line to do page scraping. You can hunt the web for the information you need without spending a a lot of time on-line. I also show you the pages where the data comes from.
Step 1: Getting the terror level.
Getting the threat level can be important to many people in the security business, You should not have to check a web page every time you need to know what it is.
lynx -dump "http://www.usasecure.org/threat.php" > threatlevel
cat threatlevel | grep "Current Threat Level:" > tl
To send to twitter add:
twidge update < tl
Current Threat Level: ELEVATED CONDITION
