Script bash para predicciones meteorológicas.
En este articulo creamos un script bash con el cual podremos visualizar las predicciones meteorológicas (el tiempo) en nuestra consola / terminal.
Las posibilidades de este script son infinitas si tienes un poco de imaginación, y todo gracias al gran trabajo de Igor Chubin.
Lo vemos…
Creamos el archivo.

Guarda el archivo y cierra el editor.
Lo puedes ejecutar, con:

bash eltiempo.sh |
El script detectara automáticamente tu localización (por IP), y te ofrecerá en la consola de manera gráfica la predicción meteorológica.
Debo decir que dependiendo de tu situación, no siempre puede identificar la población, en ese caso ofrecerá los datos desde tu longitud y latitud.
Vemos los dos ejemplos de salida…
Con población Monzón, Huesca (España):
Con latitud y longitud (otra localización desde Ucrania, donde no identifica la población).
Espero te resulte útil.
