linux bash script get user input and store in a array

Question

I want to write a bash script that will get user input and store it in an array. Input: 1 4 6 9 11 17 22

I want this to be saved as array.

Answer 1

read it like this:

read -a arr

Test:

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

print # of elements in array:

echo ${#arr[@]}

OR loop through the above array

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

Answer 2

Here's my 2 cents.

#!/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
