Thanks for the ugly one-liner. :)
In attempting to understand what it does, I have pulled it apart to
run it a piece at a time. I find the following:
/etc# TEMP=$(sensors -f | grep -m 1 F); echo $TEMP
Core0 Temp: +82.4°F
/etc# TEMP=$(sensors -f | grep -m 1 F); TEMP=$(echo $TEMP | sed 's/
[^[:digit:]]//g'); echo $TEMP;
0824
Looks like it is taking the +82.4°F and making it become 0824, which
is always > 160. So, what is it, exactly, that the magical sed is
doing, and how can I get it to convert the value correctly?
Thanks!

Here's an ugly one-liner for a cron job:
TEMP=$(sensors -f | grep -m 1 F); TEMP=$(echo $TEMP | sed
's/[^[:digit:]]//g'); if [ "$TEMP" -ge 160 ]; then echo 'TOO HOT' |
mail root -s 'TOO HOT'; fi
Of course, you could beautify it and put it into a script too. I'm
sure plenty of pluggers would be able to give you a much prettier
script too. This was just a quick and dirty one off the top of my
head.
