Found this nifty little tidbit…if you want to run the software update via the command line run the following in terminal:

sudo softwareupdate -i -a

This will ask you for your user password and run the update.  This is great for running an update on a remote computer!  I just ran the above command adding ‘;reboot’ to the end on my macpro at home for it to reboot after it finished installing.
