You're not providing a receiver for the gsub() method.  Having said  
that, though, what it seems like you're trying to do is almost  
certainly a bad idea.  It looks like you're prepared to move all  
files into the current directory.  If that's not what you intended,  
then it's probably very good that you got an error.
