Hey There,

I'm not sure what you're looking to do over time (since you'll have to deal with leap years, etc), but the two things I found in the script were the way the "if" statement was setup and the assignment for the "month" variable.

I rewrote it very quickly like this and it gives you the result you wanted:

month=`date +"%m"`
if [ "$month" -eq 3 -o "$month" -eq 6 -o "$month" -eq 9 -o "$month" -eq 12 ]
then
inc_flg=1
else
inc_flg=2
fi
echo "INC_FLG $inc_flg"

Hope that helped you out :)
