NAME
     cdio - compact disc control utility

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

DESCRIPTION
     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: freedb.freedb.org:cddb].

     -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 com-
             ments.

     -v      Verbose mode.  A second occurence of -v causes even more informa-
             tion 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
             n.

     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
             played.

     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 di-
             rectory.  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 speci-
             fied 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 speci-
             fied 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.

     previous
             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 de-
             fault 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 val-
             ues 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 numeri-
                     cal 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
                     detected.

     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 chan-
             nels; play the right subtrack on both left and right channels;
             set mono mode; set stereo mode; turn the sound off.

ENVIRONMENT
     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.

FILES
     /dev/rcd0c
     /dev/rmcd0c

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