Hi, (1) Currently "ns_db" seems to throw the "Unknown command 'xy': should be..." error message only when given also a database handle.
Example: % ns_db lalala wrong # args: should be "ns_db lalala dbId ?args?" % ns_db gethandle nsdb0 % ns_db lalala nsdb0 ns_db: Unknown command "lalala": should be 0or1row, 1row ... Does this qualify as a bug? If so, I'll file a report. (2) There is also the special handling of "open" and "close": % ns_db open unsupported ns_db command: open % ns_db close unsupported ns_db command: close Is this testing still needed? Bernd.
