I screwed up with this a little while ago and nearly released some
code that did this
a=b
a=c c=$a
echo $c
In your case (without the ``;'') the setting of fn is only done in
the environment of ``mv'' and not in the shells own environment (not
even temporarily).
I'm not clear as to whether mine should really print ``b'' or ``c''.
It seems that (a)sh and (the real) ksh print ``b'', and bash and pdksh
print ``c'' :-/
