Bash: saving ls in an array -> receiving only small letters

Question

I try to save the ls of an directory in an array, which works out, but when i look in the array all names of the directories and files are in small letters. What do I have to change, so that the names of files and dirs remain in their old notation ? also files like "Picture of Dog.jpg" are 3 entries in the array: Picture, of, Dog.jpg Is there a possibility to change that too ?

my code:

#!/bin/bash
currentDir="/home/marius/"
declare -l content=(` ls $currentDir `)
printf -- '%s ' "${content[@]}"

You are using declare -l which by definition converts it to lowercase. As per help declare:

-l  to convert NAMEs to lower case on assignment

Just use this to create array without using ls:

declare -a content=("$currentDir"/*)

now every entry of the array is like "/home/marius/Images//Picture of Dog.jpg" how can i easily remove the "/home/marius/Images//" in the entire array ? – Marius Küpper Nov 16 '14 at 17:42

You can easily do: `cd "$currentDir"; declare -a content=( * )` – anubhava Nov 16 '14 at 17:43
