Cheat Sheet

Watch

Can be used to repeatedly execute commands like retrieving the CPU temperature:

❯ sensors
k10temp-pci-00c3
Adapter: PCI adapter
Tctl:         +77.9°C  
Tccd1:        +77.5°C

So with the watch command this will be updated at a certain interval (e.g. 1s and also update the difference -d): watch -d -n 1 'sensors'
