I believe I figured out the problem. The echo command places a new line character at the end of each iteration thru the loop. I just needed to suppress the new line char for the last date. Lines changed and/or added in bold below...


outdir=/testg1/scripts

# ja fe ma ap ma ju ju ag se oc no de
set -A lasts 0 31 28 31 30 31 30 31 31 30 31 30 31
typeset -Z2 dmonth dday

month=`date +%m`
year=`date +%y`
((pmonth=month-1))

rm $outdir/date.txt

day=1
while((day<(lasts[pmonth]))) ; do
dday=$day
dmonth=$pmonth
echo ${dmonth}/${dday}/${year} >> $outdir/date.txt
((day=day+1))
done

dday=$day
dmonth=$pmonth
echo ${dmonth}/${dday}/${year}"\c" >> $outdir/date.txt



Thanks for everyone help!
