/usr/bin/xorriso

usage: /usr/bin/xorriso [settings|actions]

This program creates, loads, manipulates and writes ISO 9660 filesystem
images with Rock Ridge extensions. Write targets can be drives with optical
media or local filesystem objects.
The program operations are controlled by a sequence of commands, of which
the initial ones are given as program arguments or as lines in startup
files. Further commands may get read from files in batch mode or from
standard input in dialog mode.

  -x             Only in effect if given as program argument:
                 Execute commands given as program arguments in a sequence
                 that most likely makes some sense. Default is to execute
                 program arguments exactly in the sequence as given.

Preparation commands:
Drive addresses are either /dev/... as listed with command -devices or
disk files, eventually with prefix "stdio:" if non-CD-drive in /dev tree.

  -dev address   Set input and output drive and load eventual ISO image.
                 Set the image expansion method to growing.
  -indev address  Set input drive and load eventual ISO image. Use expansion
                 methods modifying or blind growing.

                 "gpt_crc_of:" prints GPT CRC of file disk_path.
                 For "cmd" and "as_mkisofs" see -report_el_torito.

Commands with variable length path list [...] need the list delimiter text
as end mark if they are followed by another command. By default this
delimiter is "--". In dialog and with commands read from files, the line
end serves as such a mark. With program arguments this mark can be omitted
only with the last command in the list of program arguments.
For brevity the list delimiter is referred as "--" throughout this text.

  -list_delimiter text   Set the list delimiter to be used instead of "--"
                 It has to be a single word, must not be empty, not longer
                 than 80 characters, may not contain quotation marks.

Navigation commands:

  -cd iso_rr_path  Change working directory in the ISO image. iso_rr_paths
                 which do not begin with '/' will be inserted beginning at

                 Start prog with given args and write content of iso_rr_paths
                 into its standard input. prog must at least contain one '/'.
                 lim may be any word that is not among prog and args.
  -mount drive entity id path
                 Like -mount_cmd but actually performing that command if
                 not setuid or setgid is active.

Evaluation of readability:
  -check_media [options] --
                 Try to read data blocks from the medium and report about the

              Handling of signals. Default "on" uses libburn handler.
  -error_behavior "image_loading"|"file_extraction" behavior
              Behavior "best_effort" is most endurant but may produce
              results which are correct only on the first glimpse.
  -dialog "on"|"off"|"single_line"
              After all program arguments are processed, enter dialog mode.
              "single_line" does not support newline characters within
              open quotation marks and no line continuation by trailing \.
  -page len width  Prompt user after len output lines (0=no prompt).
              width (default 80) can adjust line number computation
              to the output terminal's line width.
  -use_readline "on"|"off"
              Whether to use libreadline for dialog if available.
  -history text  Copy text into libreadline history. This command
              itself is not copied to the history list.
  -sh_style_result "on"|"off"
              If "on" do not wrap file addresses in quotation marks with
                -pwd -pwdx -ls -lsd -lsl -lsdl -lsx -lsdx -lslx -lsdlx
                -du -dus -dux -dusx -findx -find
  -backslash_codes "on"|"off"|
                   "in_double_quotes"|"in_quotes"|"with_quoted_input"
                   [:"with_program_arguments"][:"encode_output"]
              Disable or enable interpretation of \a \b \e \f \n \r \t \v
              \\ \NNN \xNN \cC in input or program arguments.
  -pkt_output "on"|"off"  Direct output to stdout and prefix each line
              by a short header which tells channel id and a mode number.
              Each such output packet is finalized by a newline.
              Channel ids are 'R:' for result lines, 'I:' for notes
              and error messages, 'M:' for -mark texts. Bit 0 of the
              mode number tells whether the newline is also part of the
              packet payload. Example of a info message with newline:
                I:1: enter option text :
              -pkt_output:on is intended for use by frontend programs.
  -msg_op "start_sieve"|"read_sieve"|"clear_sieve"|"end_sieve"|
          "parse"|"parse_silently"|"parse_bulk"|"parse_bulk_silently"|
          "compare_sev"|"list_sev" param_text
              Enable, use, or disable message sieve. Or parse lines into
              words. Or compare or list severity names.
  -named_pipes_loop mode[:mode]
                    disk_path_stdin disk_path_stdout disk_path_stderr
              Enter an EOF resistant dialog loop at a named pipe as input
              and zero, one or two named pipes as output. "-" = no pipe.
              Mode "cleanup" removes pipes at loop end. "keep" does not.
              Mode "buffered" reads all lines from input pipe before it
              opens the output pipes. "direct" opens after first input.
  -launch_frontend program [args ...] --
              Start a program, connect its stdin to xorriso stdout and
              stderr, connect its stdout to xorriso stdin.
              Use any given parameters as arguments for the started program.
  -logfile channel fileaddress  Copy output of a channel to the given file.
              channel may be 'R','I','M' as with -pkt_output or '.'
              for the consolidated -pkt_output stream.
  -mark text  If text is not empty it will get put out each time a command
              is completed.
  -temp_mem_limit number["k"|"m"]
              Set the maximum size for pattern expansion. (Default is 16m)
  -prog text  Use text as this program's name in subsequent messages
  -prog_help text  Use text as this program's name and perform -help
  -status mode|filter  Report the current settings of persistent commands.
              Modes:
                 short... print only important or altered settings
                 long ... print settings even if they have default values
                 long_history  like long plus -history: lines
              Filters begin with '-' and are compared literally against the
              output lines of -status long_history. A line is put out only
              if its start matches the filter.
  -status_history_max number  Maximum number of history lines to be reported
              with -status:long_history
  -options_from_file fileaddress
              Reads lines from the given file and executes them as commands.
  -no_rc      Only if used as first program argument, this command
              prevents reading and interpretation of these startup files:
               /etc/default/xorriso , /etc/opt/xorriso/rc
               /etc/xorriso/xorriso.conf , $HOME/.xorrisorc

  -scsi_log "on"|"off"
              Enable or disable logging of SCSI commands to stderr.
  # any text  Is ignored. In dialog mode the input line will be stored in
              the eventual readline history, nevertheless.
  -list_extras code
              Tell whether certain extra features were enabled at compile
              time. Code "all" lists all features and a headline. Other
              codes pick a single feature. "codes" lists the known codes.
  -list_arg_sorting
              Print the sorting order of xorriso commands with option -x.

              End program. Discard pending changes.


Command -page causes a user prompt after the given number of result lines.
Empty input resumes output until the next prompt. Other input may be:
  @     suppresses paging until the current action is done
  @@    suppresses further result output but continues the action
  @@@   aborts the current action
  other aborts the current action and executes input as new command
