Tnef

tnef - decode Microsoft's Transport Neutral Encapsulation Format

Beschreibung

TNEF ist ein Programm zur Dekomprimierung von MIME-Anhängen des Typs »application/ms-tnef«

• Dies ist ein typischer Microsoft-Anhang

Das Programm ermöglicht das Auspacken von in TNEF eingekapselten Anhängen

• Dies mildert die Notwendigkeit des Gebrauches von Microsoft Outlook, um diese Anhänge zu betrachten

This manual page documents the tnef filter

• tnef decodes e-mail attachments encoded in Microsoft's Transport Neutral Encapsulation Format (hereafter, TNEF), which "wraps" Microsoft e-mail attachments

Unfortunately, these "wrapped" attachments are inaccessible to any e-mail client that does not understand TNEF

• Fortunately, the tnef filter can be used by any MIME-aware client to unpack these attachments

Installation

# apt install tnef

Syntax

$ tnef [options] [FILE]
$ tnef {--help | --version}

Optionen

Option	Beschreibung
f FILE, --file=FILE	use FILE as input ('-' denotes stdin). When this option is omitted, tnef reads data from stdin.
C DIR, --directory=DIR	unpack file attachments into DIR.
x SIZE, --maxsize=SIZE	limit maximum size of extracted archive (bytes)
t, --list	list attached files, do not extract. For each file in the datafile the file name and full path will be printed. If the verbose option is also provided then this option acts as the --list-with-mime-types option and also prints the file length (in bytes) and the date of the file before the other data.
-list-with-mime-types	same as list option but also prints MIME type and content ID of each file after filename and file path.
w, --interactive, --confirmation	ask for confirmation for every action.
-overwrite	when extracting attachments, overwrite existing files.
-number-backups	when extracting attachments, if file FOO will be overwritten, create FOO.n instead.
-use-paths	honor file pathnames specified in the TNEF attachment. For security reasons, paths to attached files are ignored by default.
-save-body FILE	Save message body data found in the TNEF data. By default tnef only extracts the attached files and not the message body. There can be up to three message bodies in the file, plain text, HTML encoded, and RTF encoded. Which are saved is specified by the --body-pref option. By default the message bodies are written to a file named message with an extension based upon the type (txt, html, rtf).
-body-pref PREF	Specifies which of the possibly three message body formats will be saved. PREF can be up to three characters long and each character must be one of 'r', 'h', or 't' specifying RTF, HTML or text. The order is the order that the data will be checked, the first type found will be saved. If PREF is the special value of 'all' then any and all message body data found will be saved. The default is 'rht'.
-save-rtf FILE	DEPRECATED. Equivalent to --save-body=FILE --body-pref=r
h, --help	show usage message
V, --version	display version and copyright
v, --verbose	produce verbose output
-debug	enable debug output. (This will produce a very large amount of output.)

Bibliothek zur Handhabung von TNEF-Daten

Die Bibliothek Ktnef kann Daten im TNEF-Format handhaben. (Transport Neutral Encapsulation Format ist ein proprietäres Format von E-Mail-Anhängen, das von Microsoft Outlook und Microsoft Exchange Server verwendet wird.) Die API ermöglicht einen Zugriff auf die Anhänge und die Nachrichteneigenschaften (TNEF/MAPI). Außerdem kann man mit Ktnef im Rich Text Format verfasste Nachrichten ansehen/extrahieren.

KNOWN LIMITATIONS

tnef ignores the OEMCodePage data in the data file. It assumes Unicode data.
