[SHELL] - Info con "cat /proc "

Informazioni ottenibili da cat /proc/:

E' possibile ottenere diverse informazioni visualizzando alcuni comandi sotto /proc/. Informazioni di vario tipo, dalla memoria, alla CPU...
Vediamo come fare!

Istruzioni:
Vediamo le offerte proposte:

Utilizzeremo i comandi contenuti nella cartella /proc:

code:
