# PURPOSE: Script to check temperature of CPU cores and report/shutdown if specified temperatures exceeded
#
# AUTHOR: feedback[AT]HaveTheKnowHow[DOT]com

# Expects two arguments:
#    1. Warning temperature
#    2. Critical shutdown temperature
#    eg. using ./CPUTempShutdown.sh 30 40
#        will warn when temperature of one or more cores hit 30degrees and shutdown when either hits 40degrees.

# NOTES:
# Change the strings ">>/home/htkh" as required
# Substitute string "myemail@myaddress.com" with your own email address in the string which starts "/usr/sbin/ssmtp myemail@myaddress.com"

# Assumes output from sensors command is as follows:
#
# coretemp-isa-0000
# Adapter: ISA adapter
# Core 0:      +35.0 C  (high = +78.0 C, crit = +100.0 C) 
#
# coretemp-isa-0001
# Adapter: ISA adapter
# Core 1:      +35.0 C  (high = +78.0 C, crit = +100.0 C)
#
# if not then modify the commands str=$(sensors | grep "Core $i:") & newstr=${str:14:2} below accordingly
