Which shell? For ksh, try:
Code:
if [[ "$adfdf" = "y" || "$adfdf" = "Y" ]]

or even simpler:
Code:
if [[ "$adfdf" = [Yy] ]]

Code:
if [ "$adfdf" == "y" -o "$adfdf" == "Y" ]; then
    echo good
fi

The equality test operator is = not ==, however some unix flavour supports it
Code:
if [ "$adfdf" = "y" -o "$adfdf" = "Y" ]; then
    echo good
fi
