To be honest, I feel like headers/alignment makes it harder to parse the output. For example, in order to get all the temperature, you'll need: Code: $ weather | sed 1d | tr -s ' ' | cut -d\ -f5You first need to filter out the header, then, get rid of the alignment, and finally output the 5 field, using a custom separator. With my solution, all you need is Code: $ weather | cut -f5Way easier to parse actually, and thus, it should be easy to make a "readable output" right? Code: $ weather | sed '1iCity\tWind\tHumidity\tRain\tTemperature' | column -t |
