Shell Programming and Scripting

hi ,

I am using this to get previous date :

#!/usr/bin/ksh
date '+%m %d %Y' |
{
read MONTH DAY YEAR
DAY=`expr "$DAY" - 1`
case "$DAY" in
0)
MONTH=`expr "$MONTH" - 1`
case "$MONTH" in
0)
MONTH=12
YEAR=`expr "$YEAR" - 1`
;;
esac
DAY=`cal $MONTH $YEAR | grep . | fmt -1 | tail -1`
esac
echo "Yesterday was: $MONTH $DAY $YEAR"
}
Output : 07 21 2008

i want output as Jul 21, not as 07 21, can someone help me out.

Thanks

How about:

Code:

$ date -d "yesterday" +"%b %d %Y"
Jul 21 2008

YESTERDAY=`TZ=GMT+24 date "+%m %d %Y"`

If you are using ksh93

Code:

$ printf "%(%b %d)T\n" "yesterday"
Jul 21
$

TZ=GMT+24 date "+%b %d %Y"

Jul 22 2008
