ok, i have now compiled a lit of problems i am having at the moment, thank
you for your help.

1. when typing "ps" there are a few errors that seem to revolve around the
others when they choose, sometime the error is Segmentation Fault,
sometimes its Illegal instruction, sometime not an error at all, mostly
when there are errors there is a lot of core dumping. 

2. when typing "df" segmentation fault. 

3. when typing gcc, g++.... illegal instruction - core dump. 

4. when typing ps aux .....lets just say it doesnt get past 3 prcesses.... 

Questions. 

1. what is a core and why is it dumped? 

2. how do i format a floppy to NetBSD usage? 

3. what is an illegal instruction, and segmentaion fault? 

Sorry for the bother, and to all of you who take time out of their busy
schedules to help someone new at Unix on a mac, full marks, and may you
live a happy long and prospor life. :)
