pdfdetach(1)

NAME
pdfdetach - Portable Document Format (PDF) document embedded file extractor (version 3.04)

SYNOPSIS
pdfdetach [options] [PDF-file]

DESCRIPTION
Pdfdetach lists or extracts embedded files (attachments) from a Portable Document Format (PDF) file.

CONFIGURATION FILE
Pdfdetach reads a configuration file at startup. It first tries to find the user's private config file, ~/.xpdfrc. If that doesn't exist, it looks for a system-wide config file, typically /usr/local/etc/xpdfrc (but this location can be changed when pdfinfo is built). See the xpdfrc(5) man page for details.

OPTIONS
Some of the following options can be set with configuration file commands. These are listed in square brackets with the description of the corresponding command line option.

-list
    List all of the embedded files in the PDF file. File names are converted to the text encoding specified by the "-enc" switch.

-save number
    Save the specified embedded file. By default, this uses the file name associated with the embedded file (as printed by the "-list" switch); the file name can be changed with the "-o" switch.

-saveall
    Save all of the embedded files. This uses the file names associated with the embedded files (as printed by the "-list" switch). By default, the files are saved in the current directory; this can be changed with the "-o" switch.

-o path
    Set the file name used when saving an embedded file with the "-save" switch, or the directory used by "-saveall".

-enc encoding-name
    Sets the encoding to use for text output (embedded file names). The encoding-name must be defined with the unicodeMap command (see xpdfrc(5)). This defaults to "Latin1" (which is a built-in encoding). [config file: textEncoding]

-opw password
    Specify the owner password for the PDF file. Providing this will bypass all security restrictions.

-upw password
    Specify the user password for the PDF file.

-cfg config-file
    Read config-file in place of ~/.xpdfrc or the system-wide config file.

-v  Print copyright and version information.

-h  Print usage information. (-help and --help are equivalent.)

EXIT CODES
The Xpdf tools use the following exit codes:

0   No error.

1   Error opening a PDF file.

2   Error opening an output file.

3   Error related to PDF permissions.

99  Other error.
