Detecting CPU Temperature on Debian Linux

To read the temperature of the CPU, the package called "lm-sensors" should be installed.

Then, in Terminal, I issued the command:

sensors|grep temp|awk '{print $2}'

Sample output:
+35.0°C



or

sensors|grep temp|awk '{print $2}'|cut -b2,3,4,5

Sample output:

35.0
