This is your original script.

Code:
v_shortfield = ""

if [ $v_shortfield = "" ] ; then
echo "ravi"
else
echo "kumar"
fi

Drop the space in the line v_shortfield = ""

It should become

Code:
v_shortfield=""

if [ -z $v_shortfield  ] ; then
echo "ravi"
else
echo "kumar"
fi

if [ ! -z $v_shortfield ]

or

if [ -n $v_shortfield ]
