I'll answer this later when i'm not at work tonight if someone hasnt given a better
answer by then. I guess this is a good time to plug the excellent "Beginning Linux
Programming" book. While this isnt technically a beginner's book, it does thoroughyl
explain Linux (and Sys V) in great detail via words and code examples, and its worth
checking out. Its by Wrox Press, and can be had at Borders for ~$40. I just picked up
the Advanced Linux Programming book, its sequel, and its good, but not as good. As far
as I am concerned BLP is a must-have book. Its a little thicker than the 3rd ed
Programming Perl book, and is a flat red colour.
that book will help you really understand linux, and by extension Sys V pretty well
from the inside. I mention this book, because I remember they had a good section on
setguid, effective uid, etc.
