@kindex -concat copies ISO file content
@cindex File content, copy, -concat
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.
@*
Modes @strong{overwrite} and @strong{append} 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 --
@*
Mode @strong{pipe} 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:
@*
-concat pipe + /usr/bin/wc + /my/iso/files* --
@*
The further parameters in all modes are the iso_rr_paths of data files.
Their content gets concatenated in the copy.
