Linux下数组遍历

声明一个数组变量

直接赋值：

array[]=”Zero” array[]=”One” array[]=”Two”

declare声明：

declare -a array

小括号空格法：

array=(Zero One Two)

引号空格法：

array=”Zero One Two”

混合法：

array=([]=”Zero” []=”One” []=”Two”) 

遍历一个数组

标准for循环：

for(( i=;i<${#array[@]};i++)) 
do 
　　echo ${array[i]}
done

Zero
One
Two

for…in:

for i in ${array[@]}
do 
　　echo $i
done

Zero
One
Two

获取数组的长度

echo ${#array[@]}

echo ${#array[*]}

删除数组元素

unset array[]
echo ${#array[@]}

for i in ${array[@]}
do 
　　echo $i 
done
One
Two

切片

echo ${array[@]::}
Zero
echo ${array[@]::}
Zero One
echo ${array[@]::}
Zero One Two
echo ${array[@]:}
One Two
echo ${array[@]:}
Two
