shell脚本学习总结--break和continue的区别

[root@Director test]# cat demo.sh 
#/bin/bash
   while true;do
   read -p "Please input two number: " x y
    if ((x>9));then
        continue
    elif ((y>9));then
        break
    else
        z=$((x+y))
        echo $z
    fi
   done
echo "Execution completed!"


[root@Director test]# sh demo.sh 
Please input two number: 1 2
3
Please input two number: 10 2          #$x>9时，当次循环后面部分不在执行，而重新开始一次循环
Please input two number: 2 10　　　　　　#$y>9时，跳出整个循环体
Execution completed!
