How to know the temperature of the processor with commands in Linux?

Something we should consider the temperature of the processor, more in the summer days because the ambient temperature rises and therefore the temperature of the computer, and especially if you didn't do maintenance.

I show 2 options that are installed from the repositories for Debian.

OPTION 1

Installation:

# aptitude install lm-sensors

Use:

$ sensors

This is an option to display the temperature on the console quickly.

OPTION 2

Installation:

# aptitude install xsensors

Use:

$ xsensors
