Try this:

$ touch /tmp/file
$ tail -f /tmp/file

(from another tty)
$ echo "hello world" >> /tmp/file

(look back at the "tail -f" console and you will see "hello world")
(go back to the 'echo "hello world"' tty)

$ mv /tmp/file /tmp/file2
$ echo "hello world again" >> /tmp/file2

(go back to the "tail -f" tty and see "hello world again"   8-)

tee hee

*kinda* like when you pass call a pointer "var1" or "var2" the address
that is being pointed to is the same...
