[Shell]数组操作

• 创建数组

HOST_NAME=(master1 master2 master3 node1 node2 node3)

• 查看数组下标(索引)和值

[root@master1 ~]# echo ${!HOST_NAME[*]}
0 1 2 3 4 5
[root@master1 ~]# echo ${HOST_NAME[*]}
master1 master2 master3 node1 node2 node3

• 遍历数组

# for i in ${HOST_NAME[*]}
do
echo ${i}
done

master1
master2
master3
node1
node2
node3
