Thanks for the replies. I should state, that this is just a fun exercise thing, it's not for production use.
The gist of the problem is can one tell the day of the week if given a valid date in a "one liner", using the posix shell, cal and awk in HP-UX?
perl is not allowed because it can be done easily in perl.
"One Liner" is defined to allow for previously set variables.
So my "script" above is just a test bed for my one liner.
I feel pretty good about it, and was hoping to see if anyone could break it with valid date input, before I submit it to my friend and tell him where he's taking me to lunch! (oh yeah ... lunch is riding on this one) :-)
