is not applied to any file in the ISO image.
.TP
\fB\-close_filter_list\fR
Irrevocably ban commands \-external_filter and \-unregister_filter,
but not \-set_filter. Use this to prevent external filtering in general or
when all intended filters are registered.
Irrevocably ban commands \-concat "pipe", \-external_filter,
and \-unregister_filter, but not \-set_filter. Use this to prevent external
filtering in general or when all intended filters are registered and \-concat
mode "pipe" shall be disallowed.
External filters may also be banned totally at compile time of
\fBxorriso\fR.
By default they are banned if \fBxorriso\fR runs under setuid permission.
@ -4308,6 +4309,33 @@ Read the content of a ISO data file and write it into a data file on disk
beginning at the byte_offset. Write at most byte_count bytes.
This is the inverse of command \-cut_out.
.TP
\fB\-concat\fR mode [target | lim prog [args [...]] lim] iso_rr_path [***]
Copy the data content of one or more data files of the ISO image into a
disk file object, into a file descriptor, or start a program and copy the
data into its standard input.
The latter is subject to the security restrictions for external filters.
.br
Modes \fBoverwrite\fR and \fBappend\fR write into the target which is
given by the second parameter. This may be the path to a disk file object,
or "\-" which means standard output, or a text of the form /dev/fd/number,
where number is an open file descriptor (e.g. standard error is /dev/fd/2).
An existing target file is not removed before writing begins. If it is not
able to take content data, then this command fails.
Mode overwrite truncates regular data files to 0 size before writing into them.
Example:
\-concat append /home/me/accumulated_text /my/iso/text \-\-
.br
Mode \fBpipe\fR expects as second parameter a delimiter word which shall
mark the end of the program argument list. The third argument is the disk_path
to the program. It must contain at least one '/'. $PATH is not applied.
Further parameters up to the announced delimiter
word are used as arguments with the program start. Example:
.br
\-concat pipe + /usr/bin/wc + /my/iso/files* \-\-
.br
The further parameters in all modes are the iso_rr_paths of data files.
Their content gets concatenated in the copy.
.TP
\fB\-mount\fR drive entity id path
Produce the same line as \-mount_cmd and then execute it as external program run
after giving up the depicted drive. See also \-mount_opts.
