How to store directory files listing into an array?

Question

I\'m trying to store the files listing into an array and then loop through the array again. Below is what I get when I run ls -ls command from the console.

Answer 1

Try with:

#! /bin/bash

i=0
while read line
do
    array[ $i ]="$line"        
    (( i++ ))
done < <(ls -ls)

echo ${array[1]}

In your version, the while runs in a subshell, the environment variables you modify in the loop are not visible outside it.

(Do keep in mind that parsing the output of ls is generally not a good idea at all.)
