[Smaug] A quick scripting puzzle

[Jay Campbell]

You'd have to escape the backticks to use this inside the
LASTSUNDAY example backticks, and on re-parsing the question
it asked for the date, not just day-of-month, so you'd have
to tack more characters into the second `date`s format string.

So I'm over 80 characters anyway. The practice of shaving bytes
off code like this is called 'golfing' in some circles (i.e. perl)

j

> It took all 80.
> 
> (for x in 1 2 3 4 5;do date -d"$x sun";done)|grep `date +%b`|tail -1|cut -c9-10
> 
> This assumes a non-ancient version of `date` that understands 
> '1 sunday', '2 sunday' to mean the next two sundays.
