prlctl list -a
machines=`prlctl list -a|sed '1d'`
count=`echo "$machines"|wc -l`
((count--))
read -p "please select vm index[0-$count]:" index
if [ $index -gt $count ]; then
    echo "invlid choice!"
    exit
fi

((index++))
line=`echo "$machines" | sed -n ${index}p`
echo your choice: $line

id=`echo "$line" | tr '{}' '  ' | awk '{print $1}'`
