shell编程常见知识点

shell数组实践

#!/bin/bash

#常规操作打印数组内容
#array=(1 2 3 4 5)
#array=(`ls /tmp`)

array=(
192.168.56.10
192.168.56.12
192.168.56.13
192.168.56.14
192.168.56.15
)

for n in ${array[*]}
do
        echo $n
done

echo =========================

#c语言的方式来循环打印数组内容
#i为数组下标
for ((i=0;i<${#array[*]};i++))
do
        echo ${array[i]}
done
