Bash Version: Current Weather Conditions

img_sh

This shell script teams up Bash with jq and cURL. cURL is used to get the JSON data from the MesoWest server, then saves that blob to a .json file locally. Each line of the display shown above comes from a single printf call, where the format string can be found after the text string. Then the JSON weather data blob is piped to jq which processes the JSON. Also, jq has math operators which were used to convert the values to preferred units of measure, e.g. mm to in, etc. Americanized, basically. So, if you are in Europe, you can remove the conversion calculation for precipitation, for example, and use the default value, which is in mm. Basic mult. and div. factors were applied. Easy peasy.
