Shell – Hardware identifizieren

Hallöchen,

wieder mal ein kleines Shellskript. Das Skript ist dazu angedacht um signifikante Hardwaredetails herauszufinden. In den meisten Fällen klappt das Skript wirklich gut. An einigen Stellen funktioniert es nicht zu 100% – wichtig ist, dass es mit dem bash Interpreter aufgerufen wird, sonst buggt es.

Das Skript war eine 20 Minuten Arbeit, daher ist es nicht ganz buggfrei. 2-3 kleine Bugs hat es – aber die kann man, wenn man will, entfernen. Dennoch läuft das Skript.
