That is to overcome warnings from shellcheck

hash=($(sha256sum "$file"))
^------------------^ SC2207 (warning): Prefer mapfile or read -a to split command output (or quote to avoid splitting).

cp "$file" "/tmp/oxigraph_$1/$hash"
^---^ SC2128 (warning): Expanding an array without an index only gives the first element.
although original code is making a cute use of an array, if we are to follow
shellcheck and use mapfile or read -a - and then use explicit index -- makes it
just too cumbersome. IMHO explicit awk would be easier to read etc.
