Making an array in linux

I am trying to make an array that will have 84×28 values. The array should contain the number 1 repeated 28 times, followed by the number 2 repeated 28 times, and so on up until the number 84 repeated 28 times. I want the output to consist of 1 column and 84×28 rows, each for each number. Is there a way I can get started with this?

>Solution :

Use nested for loops that append to the array.

#!/bin/bash

array=()
for i in {1..84}; do
    for j in {1..28}; do
        array+=($i)
    done
done

echo "${array[@]}"
