Problem has been solved.  Command can be aliased through shell variable 
manipulation -or- as Neil Darlow suggested on the apcupsd mailing list 
([apcupsd-users] apcupsd and 'shutdown -p', 4/23/2004, 1:20AM):


Just change the shutdown command in the doshutdown case within 
apccontrol to the following:

     doshutdown)
         echo "UPS ${2} initiated Shutdown Sequence" | wall
         ${SHUTDOWN} -p now "apcupsd UPS ${2} initiated shutdown"
     ;;

Note: this will require APM or ACPI to be enabled in your BIOS and system
configuration (i.e. run apmd at startup for APM or enable ACPI in your
kernel). ACPI is still experimental, your mileage may vary.
