I'm trying to solve Q3 in Exercise 2. As you may know that we have some lines of text
in Feb2019 weather data. My first question is do we use TAIL/HEAD command to remove
some rows or is there some other command to do that. I thought we could use CUT
command for chopping rows but I haven't yet found the specific option to do so.
At the moment I'm using tail -28 for Feb2019 and tail -29 for Feb2020 but may be
there is a better way to do this.
Also do we have to calculate average of the column to determine which month is
hotter/wetter or are we just comparing?
