yesterday's "weekday" date

i've been going through https://www.unix.com/answers-frequent...rithmetic.html to find a cmd that will print me yesterday's date. I have found one that does it nicely


Code:
set YEST = `date '+20%y/%m/%d' | awk -F"/" '{print $1$2($3-1)}'`

as you can see its very rudimentary i.e is subtracting 1 from the day.
im looking to make this a little clever and take into account weekend such that if executed on a monday, it would return Friday's date.
