[SOLVED] How to find out hours on a computer?

Michael Piziak · 03-17-2018, 07:21 PM

Is there a linux terminal command or program (preferbably in the Ubuntu Software center, to tell how many hours of usage are on a computer?

keefaz · 03-17-2018, 07:47 PM

Code:

uptime -p

Soadyheid · 03-17-2018, 07:49 PM

To tell how long since the last reboot:

Code:

$ uptime

My system for today (I power it down each evening.)

Code:

$ uptime
 00:48:46 up 13:23,  1 user,  load average: 0.31, 0.39, 0.39

Are these commands only for the current uptime usage. I would like to know the total usage time the computer has on it since it was manufactured.

It depends on what you mean by "hours of usage". As posted uptime will tell you how long the computer has been running since last power on but not total history of run time hours.

There is a utility tuptime that can track total hours which I think is in the ubuntu repository but it can not go back to the "beginning" You can look at the SMART data of the drive to see run time hours and that would be equal to the total hours of usage assuming the drive was new when the system was first built.

That's a good idea for total "engine hours".

The amount of hours on the hard drive would be fine.

Anyone know the name of the program in "Ubuntu Software" will do this?

There is smartctl command line tool
ie with /dev/sda, as root:

Code:

smartctl -a /dev/sda | awk '/Power_On_Hours/{print $NF " hours"}'

Thank you

NOTE: You need to have smartmontools installed for the above command to work. You'll get an answer to the disk runtime in hours, if you've more than one disk you can check each separately.

The package gsmartcontrol will also give you a graphic front end if that's your thing, it'll install smartmontools as a dependency.

I installed smartmontools and now when I enter smartctl -a /dev/sda | awk '/Power_On_Hours/{print $NF " hours"}' into terminal, it doesn't give me any report. ???

Code:

Soadyheid ~ $ smartctl -a /dev/sda | awk '/Power_On_Hours/{print $NF " hours"}'
Soadyheid ~ $ sudo smartctl -a /dev/sda | awk '/Power_On_Hours/{print $NF " hours"}'
[sudo] password for Soadyheid: 
31607 hours
Soadyheid ~ $

Yup! I get nothing as well, try running it with sudo as per my second attempt above.
