shell 按行读取并保存成数组

从ip.txt里读取IP.然后把IP地址赋值到一个数组里.

IP文件如下：

Address: 220.181.26.163

Address: 220.181.26.174

Address: 220.181.26.175

Address: 220.181.26.176

Address: 220.181.19.228

Address: 220.181.19.229

Address: 220.181.26.161

Address: 220.181.26.162

Shell代码

方法一：

for x in ` awk '{print $2}' ip.txt `

{

echo $x

}

方法二：

ARRAY=($(awk '{print $2}' ip.txt))

方法三：

n=0;while read a b;do array[$n]=$b;((n++));done<ip.txt

方法四：

n=1

while ((n<=$(cat ip.txt|wc -l)))

do

ipaddr[$n]=$(cat ip.txt|sed -n "${n}p"|awk '{print $2}')

((n+=1))

done

n=`expr $n - 1`
