Yesterday I showed a way to get the serial number from a Mac OS X machine. However, as a couple of people pointed out, Apple will soon be adding another character to the serial number. This means that rather than use cut I should have used awk to allow for either serial number length. To grab the serial this way:
ioreg -l | grep IOPlatformSerialNumber | awk ‘{print $4}’
Or without the quotes:
ioreg -l | grep IOPlatformSerialNumber | awk ‘{print $4}’ | sed ‘s/”//g’
