I tend to just add ";nil" to the end as in:

   log = File.read('backup_08192008.log'); nil

You could also add:  ;log.size
                 or:  ;log.length

or some such.  The only downside is that _ won't be set to the thing  
you probably want, but since you're assigning to log anyway, that  
shouldn't matter.  (I often follow a command with:  x=_;nil   when I  
forget to capture to a variable.)
