a list of filenames (along with their inodes and stuff). So, the act of
removing a file is actually a matter of editing the directory. Back in

Isn't that all beautifully simple?
Indeed it is elegant Conrad :-) Thinking of a "directory" as a file makes reminds me that many people have told me that in UNIX "everything is a file". I am still amazed at the things that those 'files' in /proc can tell me about my hardware. It means people like me can write easy programs that can just access the data like a file instead of having to write some archane C stuff to access hardware info via some obscure low level access methods.

Click on "run_aide". Its a v.short simple script but really useful.
