how to get date in this format

[dvknn]

Hi,
From `date +%d"-"%b"-"%Y` , I get for ex: 06-AUG-2004.

How can I get 06-JUL-2004 (I would like get always
currentday-previuosmonth-currentyear)

Thanks a bunch..

This should work for you....



#!/usr/bin/ksh -p

DAY=`date "+%d"`
YEAR=`date "+%Y"`
MON=`date "+%m"`

if [ ${MON} -eq 1 ]; then
MON=12
else
let MON=MON-1
fi

case ${MON} in
1) AM="January";;
2) AM="Feburary";;
3) AM="March";;
4) AM="April";;
5) AM="May";;
6) AM="June";;
7) AM="July";;
8) AM="August";;
9) AM="September";;
10) AM="October";;
11) AM="November";;
12) AM="December";;
esac

print "${DAY}-${AM}-${YEAR}"
# EOS

currentday-previousmonth-currentyear
And what happens if today is 31-July ?

Thank You PMC.

PHV,

It doesn't matter.. As long as the month is the previous month always..Is there some other way other than the one indicated above by PMC?

Thanks

It doesn't matter
So for you, 31-June or 30-February are OK ?

Hope This Helps, PH.

Huh!!!!

I thought
DAY=`date "+%d"` would take care of the day..Would it not??

Am I missing something?

Thanks

dvknn,

PHV is right, the day if July 31 would be reported as June 31, 2004. Since this is not changing the TZ value in the OS, then this would be incorrect.

This should resolve the issue PHV brought up.

#!/usr/bin/ksh -p

DAY=`date "+%d"`
YEAR=`date "+%Y"`
MON=`date "+%m"`

set -A M30 "April" "June" "September" "November"

if [ ${MON} -eq 1 ]; then
MON=12
else
let MON=MON-1
fi

case ${MON} in
1) AM="January";;
2) AM="Feburary";;
3) AM="March";;
4) AM="April";;
5) AM="May";;
6) AM="June";;
7) AM="July";;
8) AM="August";;
9) AM="September";;
10) AM="October";;
11) AM="November";;
12) AM="December";;
esac

if [ ${DAY} -eq 31 ]; then
for ${MONTH} in "${M30[@]}"; do
if [ "${AM}" == "${MONTH}" ]; then
DAY=30
fi
done
fi
if [[ ${DAY} -eq 30 && "${AM}" == "Feburary" ]]; then
YRMOD=`expr ${YEAR} % 4`
[ ${YRMOD} -eq 0 ] && DAY=29 || DAY=28
fi

print "${DAY}-${AM}-${YEAR}"
# EOS

Whoops...moving to fast, replace this:

if [ ${DAY} -eq 31 ]; then
for ${MONTH} in "${M30[@]}"; do
if [ "${AM}" == "${MONTH}" ]; then
DAY=30
fi
done
fi

with this instead:

if [ ${DAY} -eq 31 ]; then
for MONTH in "${M30[@]}"; do
if [ "${AM}" == "${MONTH}" ]; then
DAY=30
fi
done
fi
