[Smaug] A quick scripting puzzle

For amusement, create a 1-line sh or bash command which will set
a shell variable $LASTSUNDAY to the date (2-digit day) of the last
Sunday in the current month.



Use only standard Unix utilities such as 'cat' or 'head' or 'date'.

The command shouldn't take longer than an 80-character line.

(I did this myself for creating a cron job which sends out email
announcing a meeting on the last sunday of a month).
