Command Line Weather One-Liner

This one-liner I crafted below will fetch a local weather report for different cities using the web service wttr.in. A full breakdown of its features and functions can be found on the projects GitHub page.

Perl One-Liner

perl -MLWP::Simple -se 'BEGIN {print qq~[J\033[H\033[J~}; map { getprint qq~http://wttr.in/${_}?format=${query}~; print qq~\n\n~; sleep 1} split m~,~, $loc' -- -query='%l:+%c+%C\nTemperature:+%t\nFeels+Like:++%f\nWind:+%w\nHumidity:+%h\nPressure:+%P\nPrecipitation:+%p\nLocal+Time:+%Z\nSunrise:+%S\nSunset:++%s\n' -loc='Toronto,Penetanguishene,Montreal'

Perl Breakdown

I am using the Module LWP::Simple. Normally this is included by default in a Perl installation but I have seen some instances where this was not included. So you may need to install it to make it work.

For the one-liner below replace -loc="City1,City2,City3" with the cities you wish to fetch the weather for.

The query="<query>" part can be adjusted to change how the weather is displayed. See below for more details.
