Top Forums Shell Programming and Scripting Getting week number of the "Monday" Post 302095411 by Perderabo on Monday 6th of November 2006 08:14:31 PM

I don't really follow you here. But read the date arithmetic article in our FAQ section and look at datecalc, which can probably do whatever it is that you want to do.

datecalc -c 2006 10 1

will return an integer from 0 to 6 to indicate the day of the week for Oct 1, 2006. Once you have the DOW of the first day of a month, subtract that from 9 which will give the the day of the first or second Monday in the month. So if that is larger than 7, subtract 7 from it. Now you are guaranteed to have the day of the month which is the first Monday.
