The man pages don't really do a decent job of describing this. What you
really want to do is get your hands on a copy "The Unix System Administration
Handbook" (also referred to as "The Purple Book" or "The sysadmin bible"):
Author Nemeth,Evi; Snyder,Garth; Hein,Trent R.;Seebass,Scott.
Title UNIX System Administration Handbook
Edition 3rd
Publisher Prentice Hall
Year 2000
Though generic to Unix, this book does cover RH Linux. And since most
things Unix are the same from version to version, I think you will find that
this book more than adequately answers almost every question you come up with.
As for sticky bits, briefly, here's the scoop:
t sticky bit set this on the "Other" or "World" permissions
to enable everyone the ability to access/delete
files in the directory, but restrict them
to deleting only those files *they* own
s setuid/setgid set this on the "user" permissions to force
executables to run in the environment of
that user which owns the executable
set this bit on the "group" permissions to
force an executable to run in the environment
of the group that "owns" it
set this bit on the "group" permissions of
*directories* when you want everything created
under this tree to inherit the user/group
permissions of that directory
I hope that helps, but be sure to get the the sysadmin bible. It covers all
this in pretty gory detail and explains it much better than I just did.
