How do I get the CPU temperature?

Install lm-sensors  sudo apt-get install lm-sensors After installation type the following in terminal sudo sensors-detect You may also need to run sudo service kmod start It will ask you few questions. Answer Yes for all of them. Finally to get your CPU temperature type sensors in your terminal. sensors Output: karthick@Ubuntu-desktop:~$ sensors coretemp-isa-0000 Adapter: ISA adapter Core 0: +41.0°C (high = +78.0°C, crit = +100.0°C) coretemp-isa-0001 Adapter: ISA adapter Core 1: +41.0°C (high = +78.0°C, crit = +100.0°C) w83627dhg-isa-0290 Adapter: ISA adapter Vcore: +1.10 V (min = +0.00 V, max = +1.74 V) in1: +1.60 V (min = +1.68 V, max = +1.44 V) ALARM AVCC: +3.30 V (min = +2.98 V, max = +3.63 V) VCC: +3.28 V (min = +2.98 V, max = +3.63 V) in4: +1.85 V (min = +1.66 V, max = +1.11 V) ALARM in5: +1.26 V (min = +1.72 V, max = +0.43 V) ALARM in6: +0.09 V (min = +1.75 V, max = +0.62 V) ALARM 3VSB: +3.30 V (min = +2.98 V, max = +3.63 V) Vbat: +3.18 V (min = +2.70 V, max = +3.30 V) fan1: 0 RPM (min = 10546 RPM, div = 128) ALARM fan2: 892 RPM (min = 2136 RPM, div = 8) ALARM fan3: 0 RPM (min = 10546 RPM, div = 128) ALARM fan4: 0 RPM (min = 10546 RPM, div = 128) ALARM fan5: 0 RPM (min = 10546 RPM, div = 128) ALARM temp1: +36.0°C (high = +63.0°C, hyst = +55.0°C) sensor = diode temp2: +39.5°C (high = +80.0°C, hyst = +75.0°C) sensor = diode temp3: +119.0°C (high = +80.0°C, hyst = +75.0°C) ALARM sensor = thermistor cpu0_vid: +2.050 V To see HDD temperature Install hddtemp  sudo apt-get install hddtemp Output: karthick@Ubuntu-desktop:~$ sudo hddtemp /dev/sda /dev/sda: ST3160813AS: 34° Quick command-line solution cat /sys/class/thermal/thermal_zone0/temp Applet If you are looking for a easier-to-access version, add a Hardware Sensors Monitor to Gnome-Panel: sudo apt-get install sensors-applet - this will install the sensors-applet  package Right-click the panel, select Add to panel..., then select this:  You're done. You can configure which sensors are displayed by right-clicking the applet and selecting Preferences->Sensors. A good indicator for monitoring temperature, fan speeds and voltage is psensor. It shows output of all sensors, draws graphs. Also selected outputs can be placed in indicator panel. It can be installed from Ubuntu repositories by clicking psensor  or typing: sudo apt-get install psensor Newer versions of psensor can be installed from ppa: sudo add-apt-repository ppa:jfi/ppa sudo apt-get update sudo apt-get install psensor It can also draw graphs when you tick the boxes in the graph column: Here is some information with more pictures. Another useful link In some cases not all sensors are displayed. Then you can run sudo sensors-detect and answer "yes" to all questions. But is not quite safe in some cases, but I never had any real problems with that. A safer way is to take default answers. Some additional sensors may appear.

hardinfo  is very useful tools to get all hardware information. Install hard info by sudo apt-get install hardinfo. Then you can get temperature by sensors. XSensors XSensors reads data from the libsensors library regarding hardware health such as temperature, voltage and fan speed and displays the information in a digital read-out. Open the terminal and type: sudo apt-get install xsensors lm-sensors Then detect your computer's hardware sensors by opening the terminal and running the command: sudo sensors-detect Then you will get asked a lot of questions about what hardware you want the program to detect. It is generally safe and recommended to accept the default answers to all questions, unless you know what you're doing. Xsensors vs. Psensor XSensors and Psensor both monitor the computer's temperature and the fan speeds. The difference between the two applications is in the level of detail of the information that is displayed and how the information is displayed. XSensors displays a little bit more specific information than Psensor. Psensor is smaller and more unobtrusive than XSensors and it displays itself on the desktop as a little thermometer icon in the notification area in the upper right corner of the desktop next to the clock. You can right-click the thermometer icon at any time to display the hardware temperatures. Setting up Psensor to detect your computer's hardware is done the same way as Xsensors, by installing lm-sensors to detect your computer's hardware sensors. Then detect your computer's hardware sensors running the command: sudo sensors-detect and as with Xsensors, accept the default answers to all questions. In Ubuntu 16.04 Psensor detects your computer's hardware sensors automatically without running sudo sensors-detect

Temperature without third-party apps

All the answers involve use of third-party utilities. If you want to find out the temperature without installing anything, use:

$ cat /sys/class/thermal/thermal_zone*/temp
69000
69000
67000

Temperature with Conky

If you don't mind third-party utilities I like to use Conky--a light weight system monitor.

Within conky the appropriate system variable to monitor is:

${hwmon 2 temp 1}°C

The display looks like this:

Just so you guys know, none of this install junk like sensors are needed. Just do an acpi -V and BOOM, you got everything. Example: Battery 0: Charging, 91%, 00:17:25 until charged Battery 0: design capacity 3310 mAh, last full capacity 3309 mAh = 99% Adapter 0: on-line Thermal 0: ok, 40.0 degrees C Thermal 0: trip point 0 switches to mode critical at temperature 127.0 degrees C Thermal 0: trip point 1 switches to mode hot at temperature 127.0 degrees C Cooling 0: pkg-temp-0 no state information available Cooling 1: LCD 0 of 100 Cooling 2: Processor 0 of 10 Cooling 3: Processor 0 of 10 Cooling 4: Processor 0 of 10 Cooling 5: Processor 0 of 10 WAY easier than installing all of this and kmod... Just do acpi -V. shareimprove this answer answered Jul 9 '14 at 4:17 lolzies 19515

19   Right… because you don’t have to install that one? Wrong! The program 'acpi' is currently not installed. You can install it by typing: sudo apt-get install acpi – e-sushi Oct 1 '14 at 20:32 5   And, it also doesn't always give the same information. On my machine, sensors provides the temperature whereas acpi -V doesn't show anything about it, unfortunately. – Per Lundberg Oct 16 '15 at 21:36 add a comment

/sys/class/thermal/thermal_zone0/temp this file holds cpu temperature. So, you can make a script named temp and move it to /bin then in terminal enter temp. My temp file looks like - #!/bin/bash cpu_temp=$(< /sys/class/thermal/thermal_zone0/temp) cpu_temp=$(($cpu_temp/1000)) echo $cpu_temp°C my answer is modified of www.cyberciti.biz
