Temperature scripts ....

[petercmx]

I think I have done something bad but I do not know what....

My sensors output is fine (see below) but I am getting emails every time the cron event runs complaining.

From the CPU script I get

/home/user/scripts/CPUTempShutdown.sh: line 49: [: -ge: unary operator expected
/home/user/scripts/CPUTempShutdown.sh: line 59: [: -ge: unary operator expected
/home/user/scripts/CPUTempShutdown.sh: line 49: [: -ge: unary operator expected
/home/user/scripts/CPUTempShutdown.sh: line 59: [: -ge: unary operator expected

from the comments at the top of the script it seems that what is needed is the word 'Core' or edit that to fit the output available from sensors. However, the output I see seems to relate to the motherboard ... Does anyone know how do I get the CPU sensor output?

I got some help on ubuntuforums and from that I learn that the CPU temperature is stated, it is the 'k10temp-pci-00c3' section and the temperature is probably understated by 6-8 degrees. I do not know how to edit the script to show that information though. Any ideas?

Hi there,

I'll knock a script up for you. I'm off out for the day in a mo but I'll make a start later.

Ian.

[petercmx]

magic .... thank you

[Ian]

Here you go.

Please give this script a try and let me know how you get on. If it seems to be working then I'll upload another one which is more "finished".

Ian.

EDIT: Forgot to say. Please try with a few different "warning" and "critical" temperatures just to check it's reporting as it should.

[petercmx]

Thank you for the file. I will test it later today and give you the feedback

[petercmx]

Just to let you know that there is a delay ... fell asleep at the k/b yesterday and hit a problem today. It looks like the file was created with a Windows machine and that has some encoding which is affecting what I see -- the file is all double spaced which means that it does not look right and generates quite a lot of errors when I try to run it. I will try to sort this out in the next day or so but I have to get a few other things out of the way first ...........

[Ian]

Hi,

My goodness, it didn't look like that when I uploaded it

I'll upload a fresh copy for you. Save you removing all those spaces manually.

Ian.

[Ian]

Try copy and pasting this one instead.

The script appears to be working, thank you ... if I take out >/dev/null from the cron command I can see the output on screen.

However ... I am getting an error message when running from cron. It reads

30: Syntax error: redirection unexpected

Have I missed editing something?
