Script che mostra le statistiche del computer ( linux e osx )
Circa 2 anni fa, avendo bisogno di controllare facilmente la situazione di un computer con Ubuntu via shell e con un solo comando, ho iniziato a scrivere un bash script che tenesse sotto controllo tutti i parametri del computer.
Molto spesso non si ha voglia di installare svariate gui per avere sotto controllo temperatura, frequenza cpu, spazio libero, ram, dati trasferiti, informazioni sul kernel e la distro in uso ecc ecc, o magari non vengono mostrati tutti i dati che si vorrebbero all’interno di un unico programma.
Una shell unix mette a disposizione grandissime potenzialità, e si possono ricavare, a proprio piacimento, tutte le informazioni che si vogliono, e magari metterle insieme per poterle visualizzare a schermo, inviarle su una pagina web o quant’altro.
In questo caso, dopo aver perfezionato lo script su Ubuntu, l’ho copiato su OSX su un ibook G4 e piano piano l’ho adattato ad OSX, portandolo a mostrare quasi le stesse identiche informazioni che vengono mostrate su Linux Ubuntu.
Ecco i codici sorgenti, provati sia con athlon xp che con athlon 64 (Ubuntu) che con iBook g4 (OSX).
Probabilmente, nella versione per OSX, le temperature non vengono rilevate correttamente con un processore Intel, ma questo non posso verificarlo.
