### Access Control

Dufs supports path level access control. You can control who can do what on which path with `--auth`/`-a`.

```
dufs -a <path>@<readwrite>[@<readonly>|@*]
```

- `<path>`: Protected url path
- `<readwrite>`: Account with upload/delete/view/download permission, required
- `<readonly>`: Account with view/download permission, optional

> `*` means `<path>` is public, everyone can view/download it.

For example:

```
dufs -a /@admin:pass1@* -a /ui@designer:pass2 -A
```
- All files/folders are public to view/download.
- Account `admin:pass1` can upload/delete/view/download any files/folders.
- Account `designer:pass2` can upload/delete/view/download any files/folders in the `ui` folder.


### Hidden Paths

Dufs supports hiding paths from directory listings via option `--hidden`.

```
dufs --hidden .git,.DS_Store
```

`--hidden` supports a variant glob:

- `?` matches any single character
- `*` matches any (possibly empty) sequence of characters
- no `**`, `[..]`, `[!..]`

Hide all hidden directories/files

```
dufs --hidden '.*'
```

### Log Format

Dufs supports customize http log format via option `--log-format`.

The default format is `'$remote_addr "$request" $status'`.

| variable     | description                                                               |
| ------------ | ------------------------------------------------------------------------- |
| $remote_addr | client address                                                            |
| $remote_user | user name supplied with authentication                                    |
| $request     | full original request line                                                |
| $status      | response status                                                           |
| $http_       | arbitrary request header field. examples: $http_user_agent, $http_referer |
