Instructions for command-line use
The comand-line functionality is very simple and straightforward. You just simply add commands, you would have entered in interactive mode, as a command-line arguments, separating them with semicolons. You don't need to bother about outputting the filter result, because after the last argument, the output of all filtered inventories (no paging ofcourse) will happen automatically.
INVisible.jar world my_world ; load player
This will output inventories of all players
INVisible.jar world my_world ; load player ; name airguru
This will output the inventory of player airguru
INVisible.jar world my_world ; load world
This will output contents of all chests
INVisible.jar world my_world ; load player ; items 1 2 3
This will output inventories of all players, who have items 1 or 2 or 3 in their inventories.
Remember, it's just like interactive mode, so your first command should always be "world" :)
