As we want to define the SQL grammar, it's not a good choice to use Unix

how about: flush [<sg>, <sg>] [--all-nodes] [-node <ip>]
omitting [<sg>] means flush all sgs.
-- all-nodes means flush on each nodes
-node <ip> means flush on the given node
omitting [-node <ip>] and [--all-nodes] equals [-node 127.0.0.1]
--all-nodes and -node are mutually exclusive
