See the if statements for two different ways of ORing $ANSWER3. Your error was that you did not put a space either side of "=".

Code:

#!/usr/bin/ksh93

echo "Do you want to max out the size of your lvol?"
read ANSWER3?"Enter 'y' for Yes or 'n' for No : "

if [ $ANSWER3 = "n"  -o  $ANSWER3 = "N" -o $ANSWER3 = "no" -o $ANSWER3 = "No" ]
then
    exit
fi
if [ $ANSWER3 = "y" ] || [ $ANSWER3 = "Y" ] || [ $ANSWER3 = "yes" ] || [ $ANSWER3 = "Yes" ]
then
    echo
    echo "vxassist -g $DISKGROUP growto $LVOL $MAXSIZE"
    vxassist -g $DISKGROUP growto $LVOL $MAXSIZE
fi
exit

A better was of doing what you want to do is to use a case statement as in the following example:

Code:

case $ANSWER3 in
   y|Y|YES|yes|Yes)
        break
        ;;
   n|N|no|NO|No)
        echo "No entered. Exiting"
        exit
        ;;
   *)
        echo "Invalid answer. Exiting"
        exit
        ;;
esac
echo "yes entered"
