no problem. personally I've always wondered why the proc file system exists at all as part of the file system. ya can't do anything with it; it's more of a tease than anything else. When I first started with Linux years ago I wasn't aware of it's "specialness" and looked like the monkey with his fist in a jar trying to do things with those "files" in there. ;P

In Unix (and hence Linux), everything's a file. A network connexion's a file, a pipe's a file, a disk's a file, a serial port's a file .... Mostly, you can use the same "file" operations on any of them.

I gather that on some systems, everything's virtual memory.
