Not sure how a shell script would do it, but in a perl script run at
1 min. after midnight,
my @lastmonth = qw(Dec Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov);
my $time = time; # Nail down this precise moment
my $moment = $time % 86400; # Exactly what time is it after midnight?
complain ('bitterly', $time) if $moment > 3*60; # Did cron err?
my $day = $time - $moment - 60; # Talk about one minute before midnight
my @date = (localtime ($day))[5,4,3]; # Get yr., mon., day (yesterday)
my $monthname = $lastmonth[$date[1]]; # Get last month's name
"complain" is fictitious but doesn't have to be.
I think this will do it. Now how to do it streamlined :=)
