That was my point: it is easy, just practice a bit and you will find
it very useful.

Here is another useful snippet that I used today. Between 16.04 and 18.04
something changed and an existing script that I had did not work. I needed
to change something in it.

This gets the current IP address of the machine it is running on:

  grep 'state UP' -A2 |
  tail -n1 |
  awk '{print $2}' |
  awk -F/ '{print $1}'
