I suggest you modify the two lines above to this one so you're not 
running into the interesting side effects of bash variable assignments 
and confusion of apostrophes & back-ticks.

Though I'm a little confused by the or (||) in that statement.  I would 
have thought you wanted the results of ypcat to be piped to sort.
