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
comments.
-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
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
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.
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
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
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
channels; 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
SEE ALSO
aucat(1), audioctl(1), mixerctl(1), audio(4)
HISTORY
The cdio command is based on cdcontrol, which first appeared in
FreeBSD 2.1.
