Hi Don -

Yes you're right. I will try on my own.

However, for this purpose, for some reason that function isn't returning anything.

When I pass

Code:
findSaturdayOnOrBefore "10/07/2018"

nothing returns. Any ideas?

How do these two statements fit together?

Did you look at the code for that function? Read the comments that explain what it does. That function doesn't print anything; it sets variables you can use after you call it.

Hi Don -

Ah yes - I see that. I meant to say, this environment doesn't have GNU date installed, therefore the -d switch is not accepted.

You should know by now that you need to tell us what operating system and shell you're using. So, what shell are you using?

Do you have access to a 1993 or later Korn shell? If so, what output do you get from:
Code:
ksh --version

or:
Code:
ksh93 --version

depending on how it is installed on your system?

HI Don -

The version is as follows:

Code:
  version         sh (AT&T Research) 93t+ 2009-05-01

Thank you!

With ksh version 93u+, the command:
Code:
printf '%(%m/%d/%Y)T\n' "today $((($(printf '%(%u)T' today) + 1) % 7)) days ago"

prints today's date if you run it on a Saturday and prints the previous Saturday's date if you run it on any other day of the week. Does this command work with your Korn shell? (I'm not sure which version of ksh first supported printf '%(date_format)T' date processing.)
