I can tell you are running winderz Bill, shame on you. ;)

In the *nix's the ls command is generall equ to the dir command, returning 
a list of files.  But the idea has been expanded to 'lsXX' a lot of stuff.

lsusb for instance can give one an output list of all the devices plugged 
into a machines usb bus.

lsof returns a list of open files, which on the *nix's can be piped to 
wc (word count) or grep to derive other information, like this:

root at coyote:~# lsof | wc -l
lsof: WARNING: can't stat() fuse.gvfs-fuse-daemon file system /home/gene/.gvfs
      Output information may be incomplete.
11620

So there are at the moment 11620 open files on this system.  The wc -l 
tells it not to count words, but to count lines.  Or if I wanted to see 
what the 2nd generation inetd is doing on this machine:

root at coyote:~# lsof|grep inetd
lsof: WARNING: can't stat() fuse.gvfs-fuse-daemon file system /home/gene/.gvfs
      Output information may be incomplete.

The emphasis on the *nix's is to do one small thing well, and if thats too 
much info, then pipe it to grep to pass only that which is of interest.

We need an lsof for nitros9.  It might even be possible, I'll check the
syscall menu for something that I can iterate thru the system with.  We
do have a grep BTW, works well.

Cheers, Gene
