[Noob shell script] Select entry and rename it then reload list?

[enoryw]

Can someone provide a simple example on how to select an entry and rename it, reloading the list afterwards? e.g.

Ctrl-r on oranges entry, prompt to rename, enter pears, and reload list.
printf %s\n apples oranges strawberries | fzf

I am not sure where to go from --bind 'ctrl-r:--I know bash has read ...

Much appreciated.

Here's my none tmpfile example.

#!/usr/bin/env bash
export FRUITS="$(printf '%s\n' apples oranges strawberries)"

change_fruits()
{
	if [[ $FZF_KEY == ctrl-r ]]; then
		read -e -p "$1 -> " newfruits
		if [[ "$newfruits" ]] && [[ "$1" != "$newfruits" ]]; then
			NEW_FRUITS="$(echo "$OLD_FRUITS" | sed "s/$1/$newfruits/")"
			NEW_FRUITS_POS="$(echo "$NEW_FRUITS" | sed -n "/$newfruits/=")"
			fzf_loop "$NEW_FRUITS" "$NEW_FRUITS_POS"
		else
			fzf_loop "$OLD_FRUITS" "$2"
		fi
	fi
}
export -f change_fruits

fzf_loop()
{
	export OLD_FRUITS="$1"
	echo "$1" |\
		fzf \
			--ghost "Do you like fruits?" \
			--bind "result:pos($2)" \
			--bind 'ctrl-r:become(change_fruits {} $FZF_POS)'
}
export -f fzf_loop

fzf_loop "$FRUITS"

NOTE.
To use --ghost feature, you'll need fzf commit version 4298c0b or later.

Thanks for the interesting quiz. 😄
