hey i was playing around in cygwin (in bash) and i wanted to see my environment variables, so i typed the command 'export'. One of the environment variables was PROCESSOR_LEVEL and it was equal to '15'. I was just curious to know what exactly PROCESSOR_LEVEL corresponded to and what would happen if i altered the value set to PROCESSOR_LEVEL. Is there a good site that lists off a bunch of different environment variables and then defines them all? Also, some more information about the 'export' command would be great. I know i can go into my opinions and turn 'allexport' on and off, but i dont know exactly why this would help me or what it would do. some help would be greatly appriciated, sorry for asking so many questions but i am a n00b
