Maybe you can find something useful in this example:
Code:
#!/bin/ksh
IAm=${0##*/}
tf="/tmp/$IAm.$$"
trap 'rm -f "$tf"' EXIT
find . -type f > "$tf"
nl "$tf"
printf 'Enter number of file to process or 0 to exit: '
read -r line
if [ "$line" == 0 ] || [ "$line" == "" ]
then	exit 0
fi
if [ "$line" != "${line#*[^0-9]}" ]
then	printf '%s: Response must be numeric.\n' "$IAm" >&2
	exit 1
fi
file=$(sed -n "${line}{p;q;}" < "$tf")
if [ "$file" = "" ]
then	printf '%s: Response out of range.\n' "$IAm" >&2
	exit 2
fi
printf 'Do whatever you want with file: %s\n' "$file"
