/* This is an example taken from a book, one day I might need to reference this so I thought I would save it, 
it uses many different techniques in c such as:
  - adding modules
  - create global variables using constsants and local variables inside functions
  - setting up prototyes for functions
  - defining different types such as long int, char
  - loops inside functions 
  - different style of comments 
  - break out of loop
  - if statements */

Lets break the full command down
ip -o link show eth0 | awk '{ for (x=1; x<=NF;x++) if ($x=="link/ether") print $(x+1)}'

############################################################
# If we just run the ip -o link command against regular, it just adds the ip link into one line.
This is useful if you want to awk after

ip -o link show eth0 
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP mode DEFAULT qlen 1000\    link/ether 00:1a:4a:16:01:86 brd ff:ff:ff:ff:ff:ff
