You should read the documentation, it is faster than asking here.
Typing C-h k ! gives :

** <quote> **
! runs the command dired-do-shell-command
   which is an interactive compiled Lisp function in `dired-aux'.
(dired-do-shell-command COMMAND &optional ARG FILE-LIST)

Run a shell command COMMAND on the marked files.
If no files are marked or a specific numeric prefix arg is given,
the next ARG files are used.  Just C-u means the current file.
The prompt mentions the file(s) or the marker, as appropriate.

If there is output, it goes to a separate buffer.

Normally the command is run on each file individually.
However, if there is a `*' in the command then it is run
just once with the entire file list substituted there.

The last paragraph is exactly what you want.
