RFLAG

The rflag command can be used to set room flags. An example will best illustrate:

rflag sil priv -tunnel peaceful +dark indoors - no_sum

That command will toggle the silence (abbreviations are permitted), private flags, remove the tunnel AND peaceful flag, add the dark AND indoors flag, and delete the no_sum flag. The add(+) and remove(-) operators continue to hold once invoked until reversed. The command assumes a toggle operation until it encounters either a + or a -.

If you enter rflag without any parameters, the room flags for the current room will be displayed.

You can also supply a range of rooms which can speed operations significantly. Example:

rflag 17400 17499 +dark indoors

That command would make it dark and indoors in all of the rooms ranged from 17400 and 17499 (of course, the room must exist in order to be flagged).
