NAME    [Toc]    [Back]

     cdio - compact disc audio player and control utility

SYNOPSIS    [Toc]    [Back]

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

DESCRIPTION    [Toc]    [Back]

     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 options are as follows:

     -d host:port
             Specifies  cddb host (default: freedb.freedb.org:cddb).

     -f device
             Specifies a device name such as /dev/rcd0d 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  humanreadable comments.

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

     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.
