fields is a tool for selecting columns of text. One or more individual columns and/or ranges of columns can be selected by index. Indexes can be positive (counting from the left) or negative (counting from the right). Ranges can bounded or unbounded (e.g. select all input to the left or right of N).
For versions of Ubuntu between 14.04 LTS (Trusty Tahr) and 15.10 (Wily Werewolf), as well as Ubuntu flavours that don’t include snap by default, snap can be installed from the Ubuntu Software Centre by searching for snapd.

sudo apt update
sudo apt install snapd

To install fields, simply use the following command:
