CDIO(1)                    OpenBSD Reference Manual                    CDIO(1)

     cdio - compact disc control utility

     cdio [-s] [-v] [-f device] [command args ...]

     The cdio program controls audio features of a CD drive. The device is a
     name such as ``cd0'', or ``mcd0''.

     If a device is not specified, the environment variable DISC will be used
     to find the CD device.

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

     The following options are available:

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

     -v    Verbose mode. Print as much information as possible.

     -f device
           Specifies a device name such as /dev/rcd0d or mcd0. Both absolute
           and relative paths to /dev filenames are possible.  The raw parti-
           tion name is added if needed.

     The available commands are listed below.  Only as many characters as are
     required to uniquely identify a command need be specified. The word play
     may be omitted.

     play first_track [last_track]
                 Play from track first_track to track last_track. The first
                 track has number 1 and may be omitted in all cases.

     play start_m:start_s.start_f [end_m:end_s.end_f]
                 Play from the absolute address (MSF) defined by start_m in
                 minutes, start_s, in seconds and start_f (frame number) to
                 the absolute address defined by end_m in minutes, end_s, in
                 seconds and end_f (frame number). Minutes are in the range
                 0-99. Seconds are in the range 0-59.  Frame numbers are in
                 the range 0-74.

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

     pause       Stop playing. Do not stop the disc.

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

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

     replay      Replay the current track again.

     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 mute
                 Turn the sound off.

     volume mono
                 Set the mono mode.

     volume stereo
                 Set the stereo mode.

                 and position, the current media catalog status, the current
                 values of the volume for left and right channels.

     help        Print the list of available commands.

     debug on    Enable the debugging mode of the CD device driver.

     debug off   Disable the driver debugging mode.

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

     reset       Perform a hardware reset of the device.
