array to choices .. lost

Hi Im' trying to output a list of files then make the list files as choices, need someone to give me hand.

so far here is what i got.. a bit messy

Code:

#!/bin/sh

menu_str=`ls -1 file*`

cnt=0
for i in $menu_str
do
menu_item[cnt]=${i}
cnt=$(($cnt+1))
echo $cnt 
echo ${menu_item[*]}
done

#echo $cnt ${menu_item[*]}
i=-1
echo Enter your number of choices
read choice
while [ $i -lt $cnt ]; do
        #echo "$i ${menu_item[$i]}"
        let i++
        if [ $i -eq $choice ]; then
                echo "you have chosen $i ${menu_item[$i]}"
                exit 1
        fi
done

#############################

should output something like:

Code:

echo "number  of choices <1 - $cnt>"
read $choices

Choice 1. File1111
Choice 2. File2223
Chioce 3. File1233

and so on..

If $choice is equal to array of choices then
echo you have chosen Choice 1.
echo do something...

Thanks
