how to modify an array value with given index?

Question

I want to modify an array cell, which I can do when I know the cell as a number. However here my cell position is given by $i.

pomme[`${i}`]=""

I tried without the `` and it doesn't work either?

How am I suppose to do it?

Don't get print the array content like this: echo $pomme[$i], instead use echo ${pomme[$i]}. I guess that's why you think the value isn't updated. — ShellFish

unset pomme[$i] if you are simply clearing, otherwise pomme[$i]=("") If you are having issue, check the value of your $i. — David C. Rankin

You don't need the quotes. Just use ${i}, or even $i:

pomme[${i}]=""

Or

pomme[$i]=""

In bash, you don't need the $ either for indexed arrays, a[i] will do (treated like ((...)) )
