[UFO Chicago] Meeting Followup: DDWRT: Persistent Settings Using the 'nvram' Command

[Jay F Shachter]

Centuries ago, Nostradamus predicted that Neil R. Ormos would write on Mon Jul  9 11:46:17 2012:

It is fortunate that you knew that, because the command itself does
not document that argument:

   $ nvram
   usage: nvram [get name] [set name=value] [unset name] [show]
   $

But the option unquestionably exists, and it appears to work:

   $ nvram commit
   nvram_commit(): end
   $ 

Many thanks, as always, for your knowledge and counsel.
