going slightly off your original topic, but there's code in your original
post that looks like it'll be used for testing for the last day of the month
as well. Hardcoding that might be ok if it wasn't for February 29th (which
you've accounted for this year, but which obviously needs to be changed in
the code for next February) ;)

cal(1) can be used to calculate the last day of the current month with
relative ease.

   /usr/bin/cal | awk '!/^$/{ print $NF }' | tail -1

Simply test that value against

   date +'%d'

Saves hardcoding those things :)

Regards,

Phil.
