To be even more pedantic, you actually want to do

    while read -d '' fname
    do
      echo "fname: $fname"
    done <<<"$(find . -type f -print0)"

Because if you wanted to export a variable from the loop body, it wouldn't work in your example -- the loop is running in a subshell when you pipe output into it. <<<"$(...)" is not exactly the same thing (it doesn't stream input) but it does allow you to get around this problem. For folks who suggested glob expansion -- that's okay for simple file listings, but find lets you do more complicated ones that can be quite useful. Not to mention that the suggested

    for fname in *; ...

Is not actually doing the same thing -- find lists files recursively.
