Have a look down /proc/acpi/thermal_zone, on this machine for example

# cat /proc/acpi/thermal_zone/TZ0/temperature
temperature:             50 C

Then for example...

while [ 1 ] ; do cat /proc/acpi/thermal_zone/TZ0/temperature | tr -s ' '
| cut -d' ' -f2 >> /tmp/temperaturelog ; sleep 10s ; done
