Reset PRAM in Mac OS without holding keys at startup

This command is the functional equivalent of holding down command-option-p-r at start up.  It resets the machine's PRAM. 

% sudo nvram boot-args='-p -r'

My 2009 Mac mini was having problems starting up (light on but no ding or gray apple screen).  I have not seen this startup problem since resetting the PRAM.  Hopefully this fixes the problem.

Snapshot now, so it's easy to restore when the license expires.  If you do this later, snapshot restore may not be sufficient to relicense the install.

Change the UID of files

Occasionally, the Centrify client on my corporate mac changes the UID associated with my username.  This breaks nearly everthing.  Solution is to do the following as root:

identify the old uid with %ls -ln

identify the new uid with %id -u

% find / -user -exec chown -vh {} ;
