# Name

nad - Netatalk AppleDouble file utility suite

# Synopsis

**nad** [-F *configfile*] [ls | cp | mv | rm | mkdir | rmdir | set | find] [...]

**nad** [-v | \-\-version]

# Description

**nad** is a file utility suite that can be used on a Netatalk host
to manipulate files and directories in AFP shared volumes.
AppleDouble data, which could be one of extended attributes of files,
.\_ files, or files in **.AppleDouble** directories,
as well as the CNID databases are updated appropriately
when files in the shared Netatalk volume are modified.

Using **nad** is preferable over the operating system's native file operation commands
on files and directories in a Netatalk shared volume, because it preserves the integrity
of Mac OS metadata and accuracy of the CNID database.

It depends on Netatalk running on the host system and the AFP volume being
shared by Netatalk.

Only users with appropriate permissions to access the files and directories
can use **nad** to manipulate them.
It is sensitive to afp.conf settings such as *valid users* and *invalid users*.

# Options

**-F** *configfile*

> Use *configfile* as the full path to the Netatalk configuration file.

    Note: any letter appearing in uppercase means the flag is set but it's a directory for which the flag is not allowed.

# nad cp

Copy files and directories in an AFP volume.

In the first synopsis form, the cp utility copies the contents of the
src_file to the dst_file. In the second synopsis form, the contents of
each named src_file is copied to the destination dst_directory. The
names of the files themselves are not changed. If cp detects an attempt
to copy a file to itself, the copy will fail.

When a copy targeting an AFP volume is detected, its CNID database
daemon is connected and all copies will also go through the CNID
database. AppleDouble data are also copied and created as needed when
the target is an AFP volume.

Options:

**-a**

> Archive mode. Same as **-Rp**.

**-f**

> For each existing destination pathname, remove it and create a new file,
without prompting for confirmation regardless of its permissions. (The
**-f** option overrides any previous **-i** or **-n** options.)

**-i**

> Cause cp to write a prompt to the standard error output before copying a
file that would overwrite an existing file. If the response from the
standard input begins with the character 'y' or 'Y', the file copy is
attempted. (The **-i** option overrides any previous **-f** or **-n** options.)

**-n**

> Do not overwrite an existing file. (The **-n** option overrides any previous
**-f** or **-i** options.)

**-p**

> Cause cp to preserve the following attributes of each source file in the
copy: modification time, access time, file flags, file mode, user ID,
and group ID, as allowed by permissions. If the user ID and group ID
cannot be preserved, no error message is displayed and the exit value is
not altered.

**-R**

> If src_file designates a directory, cp copies the directory and the
entire subtree connected at that point. If the src_file ends in a /, the
contents of the directory are copied rather than the directory itself.

**-v**

> Cause cp to be verbose, showing files as they are copied.

**-x**

> File system mount points are not traversed.

# nad mv

Move files and directories.

Move files around within an AFP volume, updating the CNID database as
needed. If either condition below is true, the files are copied and removed from the source.

- source or destination is not an AFP volume

- source AFP volume != destination AFP volume

Options:

**-f**

> Do not prompt for confirmation before overwriting the destination path.
(The **-f** option overrides any previous **-i** or **-n** options.)

**-i**

> Cause mv to write a prompt to standard error before moving a file that
would overwrite an existing file. If the response from the standard
input begins with the character \`y' or \`Y', the move is attempted.
(The **-i** option overrides any previous **-f** or **-n** options.)

**-n**

> Do not overwrite an existing file. (The **-n** option overrides any previous
**-f** or **-i** options.)

**-v**

> Cause mv to be verbose, showing files after they are moved.

# nad rm

Remove files and directories in an AFP volume.

The rm utility attempts to remove the non-directory type files specified
on the command line.
The corresponding CNIDs are deleted from the volume's database,
and AppleDouble metadata is removed.

The options are as follows:

**-R**

> Attempt to remove the file hierarchy rooted in each file argument.

**-v**

> Be verbose when deleting files, showing them as they are removed.

# nad mkdir

Create directories in an AFP volume.
The corresponding CNIDs are added to the volume's database,
and AppleDouble metadata is initialized.

The options are as follows:

**-p**

> Create intermediate directories as required.
If an intermediate or the target directory already exists, it is not
considered an error.

**-v**

> Be verbose when creating directories, showing them as they are created.

# nad rmdir

Remove empty directories in an AFP volume.
The corresponding CNIDs are deleted from the volume's database,
and AppleDouble metadata is removed.

The volume root directory and its parent directories cannot be removed.

The options are as follows:

**-p**

> Each operand is treated as a pathname of which all components will be
removed, if they are empty, starting with the last most component.
Will not remove the volume root directory or its parents.

**-v**

> Be verbose when removing directories, showing them as they are removed.

# nad set

Set metadata on files.

The set utility alters metadata on files within an AFP volume.

The options are as follows:

**-t** *type*

> Change a file's four character file type.

**-c** *creator*

> Change a file's four character creator type.

**-l** *label*

> Change a file's color label. See list below for available colors.

**-f** *flags*

> Change a file's Finder flags. See list below for available flags.
Uppercase letter sets the flag, lowercase removes the flag.

**-a** *attributes*

> Change a file's attributes. See list below for available attributes.
Uppercase letter sets the flag, lowercase removes the flag.

# nad find

Find files and directories in an AFP volume.

This returns a list of paths that wholly or partially match the given name.

It takes one option:

**-v** *path*

> Use path to the shared volume to search rather than the current working
directory.

# Examples

List files in a shared AFP volume:

    $ nad ls -al /srv/afpshare
    ---Nic-s--- ------ --- ---- ----           2   .
    ----------- ------ --- ---- ----           1   ..
    ----i---b-- ------ --- APPL SBMC          40   AppleShare IP Browser
    ---------v- ------ --- ---- ----          36   Network Trash Folder
    -------s-v- ------ --- ---- ----          35   TheVolumeSettingsFolder
