Gee, a little slip of the wrist,
(dired-do-shell-command "head -c 999 * |sum" nil (quote ("FlashXXV9Z9sz")))
(dired-do-shell-command "head -c 999 *|sum" nil (quote ("FlashXXV9Z9sz")))
and it goes and gets every file in the directory.
Yes I know it is all well documented, but I can't think of any computer
language where such a tiny difference can make such a big difference.
I don't have an exact solution. All I know is it will bite the reader
sooner or later.

dired-do-shell-command claims to have a safety feature for this:
`*' and `?' when not surrounded by whitespace have no special
significance for `dired-do-shell-command', and are passed through
normally to the shell, but you must confirm first.
AFAICS, due to a logic bug this feature has never worked.
Hopefully now it does.
I still have no idea what:
To pass `*' by itself to the shell as a wildcard, type `*\"\"'.
is supposed to mean though.

I see the manual explains it better:
If you want to use `*' as a shell wildcard with whitespace around it,
^^^^^^^^^^^^^^^
write `*""'. In the shell, this is equivalent to `*'; but since the `*'
is not surrounded by whitespace, Dired does not treat it specially.

Well
GbTS> `*' and `?' when not surrounded by whitespace have no special
such design is too risky for the general public anyway.
