for ip in `cat ip.txt`
do
        {
        ping -c1 $ip &> /dev/null
        if [ $? -eq 0 ];then
                ssh $ip "echo $pass | passwd --stdin $USER"
                if [ $? -eq 0 ];then
                        echo "$ip" >> /root/successful_`date +%F`.txt
                else
                        echo "$ip" >> /root/fail_`date +%F`.txt
                fi
        else
                echo "$ip" >> /root/uncon_`date +%F`.txt
        fi
        }&   #将语句放到后台执行，也可以不需要
done
#wait命令可以让前面的语句全部执行完，再执行后面的语句
wait
echo "modify is successful!"
