Hi

Try the following command

cal 01 2006 | tr -s " " | sed -e '1,2d' | awk -F" " '{print $1}'

use the following in awk
$1 - For Sundays
$2 - For Mondays
$3 - For Tuesdays
and so on

Hope this helps

Regards
Bobby

Read the date arithmetic article in our faq section. My datecalc script can do stuff like this:

#! /usr/bin/ksh

desiredday=$1
year=$2

(( cday = $(datecalc -j $year 1 1) + (($desiredday - $(datecalc -d $year 1 1) + 7)%7) ))
(( limit = $(datecalc -j $year 12 31) ))
while ((cday<limit)) ; do
        datecalc -j $cday
        ((cday=cday+7))
done
exit 0

The first argument is the day of the week (0 - 6) and the second argument is the year.
./script 6 2006 will give you all saturdays for the current year.

i am using datecalc function....after subtracting 6 from dt1, i am getting
2006 1 15

dt1=2006 01 27
datecalc -a $dt1 - 6

but i want the output as
2006 01 15

i searched the forum... if i get the "day" individually and perform operation, i can use typedef. but i am using the full date and subtracting 6 from it. how to get the desired output as above?

typeset -Z2 month day
datecalc -a $dt1 - 6 | read year month day
echo $year $month $day

I have one text file which has many date fields.

Date field is in "mm/dd/yyyy" format.

I want to replace every yyyy to yy format.

If i have one year value namely 2005, i can replace as

s/2005/05/g

Since i have many values, how to generalise the the above replacement ?
Through script, i need to grep and replace.

Thanks in advance.
