Shell Programming and Scripting

Hi,

Please can someone help me in getting first sunday date of a month.

Code:

i_year=`date +%Y`
ny_first_sun_nov=`cal  10 $i_year | sed  '/^$/d' |head -3 |tail -1| rev | cut -c1`

This works good if the first sunday has a value but not if it is blank and first sunday falls on second week.

cal -m where I can make Monday as first day of the week so that Sunday always have a value does not work on Solaris.

Please can someone help me to get this corrected?

Thanks

I noticed that you opened several threads lately regarding date arithmetic and you didn't apply any suggestions posted in your previous threads!

Before going forward I suggest you to refer this thread in FAQ section.

Thanks Yoda,

I will close the other threads with suggestions and comments,
All the threads correspond to different questions/ arithmetic but I should close them if they are resolved.

Thanks again

Try ..

Code:

cal 12 2012 | awk 'NF==7 && !/^Su/{print $1;exit}'

Its not working,

cal 12 2012 | awk 'NF==7 && !/^Su/{print $1;exit}'

is giving me S
I am looking for value that is 1

That's working for me.

Code:

$ cal 1 2012 | awk 'NF==7 && !/^Su/{print $1;exit}'
1
$

Code:

$ cal 1 2012
    January 2012

15 16 17 18 19 20 21
22 23 24 25 26 27 28
29 30 31

Please use /usr/xpg4/bin/awk on solaris
Also, post the output of
