Tiny Deathstars of Foulness

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’

During various automations in Mac OS X it helps to grab some key unique identifiers for machines. Two very common identifiers are the serial number of a computer and the MAC Address. To grab a systems serial number I usually use ioreg to run the following, which simply outputs a systems serial number:
ioreg -l | grep IOPlatformSerialNumber | cut -c 37-46
Because a system can have multiple MAC addresses (one per unique adapter), I will also use ioreg to grab those:
ioreg -l | grep IOMACAddress
Or to just see an output of the first in the list (en0):
ioreg -l -w 0 | grep IOMACAddress | cut -c 37-48 | head -n 1
