Hi there, I wanted to monitor the temperature of a server and shut it down automatically when it reaches certain threshold. At the same time it should keep me informed about the status via email. I found that http://cahbojonegoro.wordpress.com/2008/12/15/cpu-temperature-monitor-script/ script and changed it a little: #!/bin/sh ### Temperature Monitor ### Auto Shutdown if CPU Temperature is over threshold ## Define threshold for CPU Temperature threshold=75 ## Get CPU Temperatur using lm-sensor t1=`/usr/bin/sensors | nawk ?/temp2/ {print substr($2,2,2)}?` if test $t1 -gt $threshold then mail -s "safety-shutdown" name at domain.de < /home/chris/heat.txt echo ?CPU Temperature is exceeding threshold ? Shutting down in 10 sec ??.? sleep 10 shutdown -h now else mail -s "test" name at domain.de < /home/chris/textdatei.txt echo ?Temperature still on the safe range ? echo ?CPU: $t1?C? fi Cronjob is runnig the script periodically. lm-sensors itself as well as the email-thing work well, but it seems that the script doesn't get the needed info from lm-sensors. My error-message is: nawk: 1: unexpected character 0xe2 test: 23: 75: unexpected operator ???Temperature still on the safe range ??? ???CPU: ??C??? Since I don't have much experience with scripts, I don't really understand what the problem could be. Any suggestions what do do? I am using Ubuntu Linux 8.04.2 kernel 2.6.24-24, the mainboard is an Asus Pundit-R AB-P 2800 using an it8712-isa-0260 chip.** **** ** **Thanks a lot in advance and greets from Bavaria! ** **Chris
