Is there a terminal command or a program for reading the CPU Temperature?

Thank you.

You can use ā€œpsensorā€. Download it from Software center

root@tegra-ubuntu:~# cat /sys/devices/virtual/thermal/thermal_zone*/temp
37000
36000
36500
36500
32000
32750

and
cat /sys/devices/virtual/thermal/thermal_zone*/type
will yield the names of the temperature probes.
installing lmsensors also works well!
Then a simple call of ā€˜sensorsā€™ gives nice output:

CPU-therm-virtual-0
Adapter: Virtual device
temp1: +38.5Ā°C (crit = +101.0Ā°C)

GPU-therm-virtual-0
Adapter: Virtual device
temp1: +38.0Ā°C (crit = +101.0Ā°C)

MEM-therm-virtual-0
Adapter: Virtual device
temp1: +36.0Ā°C (crit = +101.0Ā°C)

PLL-therm-virtual-0
Adapter: Virtual device
temp1: +36.0Ā°C

Tboard_tegra-virtual-0
Adapter: Virtual device
temp1: +31.0Ā°C

Tdiode_tegra-virtual-0
Adapter: Virtual device
temp1: +33.5Ā°C

(btw this is idle with about 25 degrees room temperature AND that big fanless heatsink installed)
