You should always read a script before running it. :)

Your result is anomalous. I've been using that for 4 years now, with never
an error. Testing today on a machine up for 3 days, so it has today's
newest kernel, gives:

root at baal:~# echo $KERNEL_HIGHEST
3.2.0-30
root at baal:~# echo $KERNEL_CURRENT
3.2.0-29

Perhaps your dpkg database is fresh from a install (apt-get update never
ran)? If not, please poke at the code, or contact me privately with the
results of:

dpkg -l linux-image\* | cat

The cat prevents dpkg from truncating version numbers due to terminal width.
