read it like this:

像这样读:

read -a arr

read -a arr <<< "1 4 6 9 11 17 22"

print # of elements in array:

print数组中的元素数:

echo ${#arr[@]}

OR loop through the above array

OR循环上面的数组

for i in ${arr[@]}
do
   echo $i # or do whatever with individual element of the array
done

这是我的2美分。

#!/bin/sh

read -p "Enter server names separated by 'space' : " input

for i in ${input[@]}
do
   echo ""
   echo "User entered value :"$i    # or do whatever with individual element of the array
   echo ""
done
