Ecco un semplice script che, se eseguito da terminale, permette di ottenere informazioni su ogni batteria presente nel vostro computer portatile. create un file (es: /usr/local/bin/battery.sh) al suo interno inserite quanto segue

salvate il file date al file i permessi di esecuzione (es: chmod +x /usr/local/bin/battery.sh) usate lo script (eseguente da terminale: /usr/local/bin/battery.sh)
