,----[ C-h f dired-do-shell-command RET ]
| dired-do-shell-command is an interactive autoloaded compiled Lisp function in
| If COMMAND ends in `&', `;', or `;&', it is executed in the
| background asynchronously, and the output appears in the buffer
| `*Async Shell Command*'. When operating on multiple files and COMMAND
| ends in `&', the shell command is executed on each file in parallel.
| However, when COMMAND ends in `;' or `;&' then commands are executed
| in the background on each file sequentially waiting for each command
| to terminate before running the next command. You can also use
| `dired-do-async-shell-command' that automatically adds `&'.
