     cdio - compact disc control utility

     cdio [-sv] [-d host:port] [-f device] [command args ...]

     The cdio program is a compact disc control utility, with support for
     playing audio CDs and TAO CD writing.

     If no command is given, cdio enters interactive mode, reading commands
     from the standard input.

     The options are as follows:

     -d host:port
	     Specifies a CDDB host [default:].

     -f device
	     Specifies the name of the CD device, such as /dev/rcd0c or mcd0.
	     Both absolute and relative paths to /dev filenames are possible;
	     the raw partition name is added if needed.

     -s	     Silent mode.  Do not print table headers or human-readable

     -v	     Verbose mode.  A second occurrence of -v causes even more
	     information to be printed.

     The available commands are listed below.  Only as many characters as are
     required to uniquely identify a command need be specified.	 If no command
     is given, only a track number or range, then play is assumed.

     blank   Minimally blank the disc.

     cddbinfo [n]
	     Print the Table Of Contents (TOC) after matching the disc with
	     the CDDB.	In case of multiple matches, reissue the command with

     cdid    Print the disc ID that will be used for matching with the CDDB.

     cdplay [track1-trackN ...]
	     Play specified tracks from disk.  Unlike play, the CD player need
	     not be connected to an audio device; instead it rips tracks from
	     disk and outputs audio data to the default audio(4) device or
	     aucat(1) socket.  Both individual tracks and track ranges may be
	     specified.	 If range is specified in descending order tracks will
	     be played in descending order.  If the first value in the range
	     is omitted, tracks from first track on disk to the specified one
	     will be played.  If the last value in the range is omitted,
	     tracks from the specified track to the last track on disk will be

     cdrip [track1-trackN ...]
	     Rip specified tracks from disk.  Audio tracks are saved as WAVE
	     sound files.  All tracks will be saved in the current working
	     directory.	 If parameters are omitted, all tracks are ripped.
	     Both individual tracks and track ranges may be specified, in the
	     same format as the cdplay command.

     close   Inject the disc.

     debug on | off
	     Enable/disable the debugging mode of the CD device driver.

     device devname
	     Make devname the current CD device.  This is the equivalent of
	     quitting cdio and restarting with a different device.

     eject   Eject the disc.

     exit    A synonym for quit.

     help    Print the list of available commands.

     info    Print the Table Of Contents (TOC).	 If -v is also specified, the
	     current features and current profile is printed.  If -v is
	     specified twice, the complete list of supported profiles and a
	     hex dump of each current feature is printed.

     next    Play the next track.  If we're at the last track, stop.

     pause   Stop playing.  Do not stop the disc.

     play [track1[.index1] [track2[.index2]]]
	     Play from track1 to track2; an optional index point can be
	     specified for each track.	If only one track is specified, play
	     from that track to the end of the disc.  If no tracks are
	     specified, play the whole disc.

     play [[tr1] m1:s1[.f1] [tr2] [m2:s2[.f2]]]
	     Play from the absolute address (MSF) defined by m1 in minutes, s1
	     in seconds, frame number f1, to the absolute address defined by
	     m2 in minutes, s2 in seconds, frame number f2.  If a track number
	     is specified (trX), then the minutes, seconds, and frame numbers
	     are relative to the start of that track.  Minutes are in the
	     range 0-99.  Seconds are in the range 0-59.  Frame numbers are in
	     the range 0-74.

     play [#block [len]]
	     Play starting from the logical block using len logical blocks.

	     Play the previous track.  If we're at the first track, restart.

     quit    Quit the program.

     replay  Replay the current track.

     reset   Perform a hardware reset of the device.

     resume  Resume playing.  Used after the pause command.

     set lba | msf
	     Set LBA (lba) or minute-second-frame (msf) ioctl mode.  The
	     default is minute-second-frame ioctl mode.

     status  Print information about the disc: the current playing status and
	     position, the current media catalog status, and the current
	     values of the volume for left and right channels.

     stop    Stop the disc.

     tao [-ad] [-s speed] trackfile ...
	     [command line only]  Write a track-at-once CD containing the
	     specified trackfile.

	     The options are as follows:

	     -a	     Write files as audio tracks.  File formats of audio
		     tracks may be CDDA or WAVE with 2 channels of PCM audio,
		     signed 16-bit (little endian) values sampled at 44100 Hz.
	     -d	     Write files as data tracks (the default).
	     -s speed
		     Specify a write speed for tracks.	speed may be a
		     numerical value between 1 and the maximum speed supported
		     by the media and drive, or one of the literal strings
		     ``auto'' or ``max'', meaning the optimal or maximum speed

     volume left_channel right_channel
	     Set the volume of the left channel to left_channel and the volume
	     of the right channel to right_channel.  Allowed values are in the
	     range 0-255.

     volume left | right | mono | stereo | mute
	     Respectively: play the left subtrack on both left and right
	     channels; play the right subtrack on both left and right
	     channels; set mono mode; set stereo mode; turn the sound off.

     DISC, CDROM     Specifies the name of the CD device to use.  If both DISC
		     and CDROM are set, DISC takes precedence.	If neither
		     DISC nor CDROM are set, the default is cd0.  See also the
		     -f option, above.

     AUDIODEVICE     Name of the aucat(1) socket to connect to, or path to the
		     audio(4) device to use.


     aucat(1), audioctl(1), mixerctl(1), audio(4)

     The cdio command is based on cdcontrol, which first appeared in
     FreeBSD 2.1.
