A bit on the side, but more user friendly:

You should change the error message on line 335 to explain how to use 
lszfs, or add a "help lszfs" command.

Instead of merely complaining about "wrong number of arguments", how 
about stating something like "wrong number of arguments, need at least 
pool name"?
