However, if there is a `*' in the command then it is run
just once with the entire file list substituted there.
+If there is no `*', but a `?' in the command then it is still run
+on each file individually but with the filename substituted there
+instead of att the end of the command.

No automatic redisplay of dired buffers is attempted, as there's no
telling what files the command may have changed. Type
\\[dired-do-redisplay] to redisplay the marked files.
