Dump AppleSingle/AppleDouble format data

## Name

addump - Dump AppleSingle/AppleDouble format data

## Synopsis

**addump** \[-a\] \[*FILE* \| *DIR*\]

**addump** \[-e\] \[*FILE* \| *DIR*\]

**addump** \[-f\] \[*FILE*\]

**addump** \[-d\] \[*FILE*\]

**addump** \[-h \| -help \| –help\]

**addump** \[-v \| -version \| –version\]

## Description

**addump** dumps AppleSingle/AppleDouble format data.

It can dump various AppleSingle/AppleDouble data created by mailers, archivers, Mac OS X, Netatalk and so on.

With no *FILE* \| *DIR*, or when *FILE* \| *DIR* is ‘-’, read standard input.

## Options

**-a** *FILE* \| *DIR*

This is the default. Dump AppleSingle/AppleDouble data for *FILE* or *DIR* automatically. If *FILE* is not in AppleSingle/AppleDouble format, look for extended attributes, *.AppleDouble/FILE* and *.\_FILE*. If *DIR*, look for extended attributes, *DIR/.AppleDouble/.Parent* and *.\_DIR*.

**-e** *FILE* \| *DIR*

Dump extended attributes of *FILE* or *DIR*.

- **-f** *FILE*

  Dump *FILE*. Assume FinderInfo to be FileInfo.

- **-d** *FILE*

  Dump *FILE*. Assume FinderInfo to be DirInfo.

**-h**, **-help**, **–help**

Display the help and exit

**-v**, **-version**, **–version**

Show version and exit

## Note

There is no way to detect whether FinderInfo is FileInfo or DirInfo. By default, addump examines whether the file, directory or parent directory is .AppleDouble, filename is .\_\*, filename is .Parent, and so on.

When setting option **-e**, **-f** or **-d**, assume FinderInfo and don’t look for other data.
