HELP: File with parameters for en/decryption. TYPE: STRING SYNTAX: PARFILE/PARF/PAFILE/PARAMETER_FILE='str'
This parameter specifies a file name containing FLAM parameters.
Specifying a parameter file permits default values to be overridden without the need for complex inputs in the command line.
This specified file can be created interactively using a text editor.
Syntax restrictions for FLAMv4 or older:
PARFILE=parameter filename
PARF=parameter filename
-parfile=parameter filename
parfile=parameter filename
parfile
specification. Furthermore, it may not change the -show
parameter whose setting is determined when the command line is
analyzed.Settings such as the type of operation (compress or decompress), the input/output files, etc., can be entered either directly in the flam command or explicitly in a parameter file. Implicit settings are also possible simply by omitting certain information, for example the compression mode for the compression procedure. The settings which apply automatically if any specifications are missing or redundant are determined by evaluating certain information in a fixed sequence; this results in an order of priorities, which is based both on the category and on the origin of the information. Since parameter files may refer to other parameter files, it is possible for several such files, possibly containing contradictory information, to be concatenated. The first of these parameter files has priority over all the others. If the same parameter is specified more than once within a parameter file, however, only the final specification is valid. The information which is used to determine the FLAM settings is evaluated in the following order:
If the command itself contains any contradictory or incompatible information, it is rejected and an error message is output.
The following priority rules apply in all other situations:
-parfile=...
or by default.
If the operation is not specified as a FLAM parameter either, the
installed default value, i.e. the default operation, is taken instead.stdin
and stdout
files are used. In the case of FLAM parameters,
specifications with a lower priority are always completely overridden
by the higher priority, i.e. it is not possible to define a list of
input specifications partly in the command itself and partly in the
parameter file or in the form of default values. The list in the
command cancels out the list at the lower specification level.
