Perhaps something like this:

Code:
#!/usr/bin/env ksh

read SOMEINPUT?"Enter your input: "
FILE="/tmp/somefile"
if [[ $(grep -i -c $SOMEINPUT $FILE) -ge 1 ]]; then
    echo "$SOMEINPUT exists in $FILE."
else
    echo "No match found for $SOMEINPUT in $FILE."
fi

Might be worth storing the list in a variable and running a select loop on it
