Yep. Just search for "shell scripting" (including the double-quotes) at
<http://linuxgazette.net/search.html> and you'll see it right at the top
of the stack.

[grin] Just a little, John. "rsync" is intended for file transfer in
general, no restriction as to type. I use it with the "-e ssh" option
(actually, I have "RSYNC_RSH=/usr/bin/ssh" set in my "~/.bash_profile"),
so it uses SSH as the underlying mechanism, but "rsh", although
deprecated in most situations, is also type-independent (although it's
somewhat clunky - the STDIN/STDOUT method of transferring data does make
it _look_ like a text-specific gadget.)
