Here is a sample script that shows a few ways to do what you're trying to do that work with both bash and ksh:
Code:
printf "Enter answer: "
while read answer
do      if [ "$answer" = "y" ] || [ "$answer" = "Y" ]
        then    printf "true: %s\n" \
                        'if [ "$answer" = "y" ] || [ "$answer" = "Y" ]'
        else    printf "false: %s\n" \
                        'if [ "$answer" = "y" ] || [ "$answer" = "Y" ]'
        fi
        if [[ "$answer" == [yY] ]]
        then    printf "true: %s\n" \
                        'if [[ "$answer" == [yY] ]]'
        else    printf "false: %s\n" \
                        'if [[ "$answer" == [yY] ]]'
        fi
        if [[ "$answer" == [yY]* ]]
        then    printf "true: %s\n" \
                        'if [[ "$answer" == [yY]* ]]'
        else    printf "false: %s\n" \
                        'if [[ "$answer" == [yY]* ]]'
        fi
        case "$answer" in
        ([yY])  printf "match: case %s\n" '([yY])';;
        ([nN])  printf "match: case %s\n" '([nN])';;
        (*)     printf "no match: cases ([yY]) and ([nN])\n"
        esac
        case "$answer" in
        ([yY]*) printf "match: case %s\n" '([yY]*)';;
        ([nN]*) printf "match: case %s\n" '([nN]*)';;
        (*)     printf "no match: cases ([yY]*) and ([nN]*)\n"
        esac
        printf "Enter another answer: "
done
printf "\nDone.\n"

The [[ expr ]] tests are not available in a Bourne shell and are not required by the POSIX standards; the other forms are required by the POSIX standards and will also work with an old Bourne shell.
