How large is very large? I wrote the below zsh
to create large files that look like this:

    1f6920fd18f25904026c59ee560f53c815dde2f854e21e40ceb3f3d58fa55ab9
    593bc90bcecd16dada33273deb2a79e593703844ccc65a2139928124357c7755

With 10 000 lines there was still no
difference. With 100 000 lines and a file size
of 6.2M, the results were... identical.

create-bogus-file () {
    local file=$1
    local lines=$2
    rm -r $file
    for l in {0..$lines}; do
        dd if=/dev/urandom count=1 2> /dev/null |
            sha256sum |
            ( read rnd _; echo $rnd >> $file )
    done
}
