Question Using default value with getopts and case
Hey Guys

I have a program in shell which is reading default values from a file

filename: default
Code:
MAN=Value1
MANPD=997
REPPD=P1G6

Now the code calling is

Code:
#!/bin/sh

. /home/default

while getopts t:D: name
do
 case $name in
  t) TYPE=$OPTARG;;
  D) PDN=${OPTARG:=$MAN};;
esac
done

echo $TYPE
echo $PDN

echo $MAN

So basically if any value to -D is given PDN gets that, else it gets the value of MAN.. now $MAN is giving an output but $PDN (when not set @ runtime) is not setting itself to $MAN..

What am I doing wrong??
