why?

  Because mostly you are just shelling out. Also you can't just use any mac addr as some bits are reserved, e.g. multicast. But you can collapse that as so or suchlike: ifconfig eth34 hw ether $(openssl rand 6 | xxd -p | sed 's/\(..\)/\1:/g; s/:$//') Obviously doing this is wrong anyway but that will do what your script does.

    To each his own, my point was readability, but some might prefer a one-liner such as yours.

      Well the whole point of scripting is to get the job done.
