CDCONTROL(1)            FreeBSD General Commands Manual           CDCONTROL(1)

NAME
     cdcontrol - compact disc control utility

SYNOPSIS
     cdcontrol [-sv] [-f device] [command ...]

DESCRIPTION
     The cdcontrol utility is a program to control audio features of a CD
     drive.  The device is a name such as cd0 or mcd0.

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

     The following options are available:

     -s      Silent mode - do not print table headers and human readable
             comments.

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

     -f device
             Specify a device, such as /dev/cd0c or mcd0.  Both absolute path
             and relative to /dev filename are possible.  Suffix `c' is added
             to the device name 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
     can be omitted or the characters ``+'' and ``-'' can be used in the place
     of next and prev.
