Compare string output to int value?
Hi,

i'd like to implmeent emergency shutdown script in case our AC dies and the temperature rises too high.

I can get core temperatures with:
sensors | grep Core | cut -c15-16

Result is:
23
18
18
13
21
18
15
17

How can I check if any of the cores is above eg. 80 (that's C of course, not F) and initiate shutdown?

Thanks

Hammer & Screwdriver Here is one way to think about this
raw file, or your output from the grep
Code:
> cat file11
23
18
18
13
21
18
15
17

if any entry >= 24, write it
then if the file has something in it, "do something"
Code:
> awk '$1>=24' file11 >file12
> if [ -s file12 ]; then echo "do something" ; fi

nothing done because that criteria was not met

if any entry >= 23, write it
then if the file has something in it, "do something"
Code:
> awk '$1>=23' file11 >file12
> if [ -s file12 ]; then echo "do something" ; fi
do something

something was echo'd
