Description

The conversions known by ftpd(ADMN) and their attributes are stored in an ASCII file that is structured as shown in the ``Format'' section. Each line in the file provides a description for a single conversion. Fields are separated by colons (:).

Prefix and postfix

The prefix fields are not currently used. The postfix fields define extensions to be added or removed from user-specified filenames. The ``addon postfix'' field is assumed to have been appended to a real filename and is removed prior to looking up the file. The ``strip postfix'' field is appended to the user-supplied filename prior to looking up the file. This is somewhat counter-intuitive.

The file name that results is available for use in the ``external command'' field by using the special string ``%s''.

Types

The following types are defined:

T_ASCII: ASCII files
T_DIR: directories
T_REG: regular files.

A type specification indicates that only files of the specified type are allowed to be converted. This is used to prevent transferring of compressed files in binary mode or attempts to compress directories.

More than one type may be specified by separating them with the ``|'' character.

Options

Some built-in options are known to the FTP server and will cause special information to be displayed in the log file (see ftplog(SFF)) if transfers are being logged. These are:

O_COMPRESS: the file was compressed during transfer
O_TAR: the file was tar'd during transfer
O_UNCOMPRESS: the file was uncompressed during transfer.

More than one option may be specified by separating them with the ``|'' character.

Example

The following example shows a conversion that causes files whose names end in ``.tar'' to have their suffix removed. The resulting filename is used as an argument to the tar(C) command. The transfer is not allowed to be performed in ASCII mode and a special ``tar'' flag will be written to the transfer log.
