cdctrl command is a program that opens a CDROM device and may be used for interactive control of the CDROM including play starting at a track, next track, previous track, stop, pause, display info, display CDROM status, and display CDROM directory. This program may be used as a daemon to control an audio CDROM device.

The commands to the cdctrl command are:

device

-V

Print out version and build information.

-h

Display help.

-v

Display help.

-D

Enable runtime debugging.

-c

Output CR-LF at end of each line, not LF.

By default, cdctrl opens /dev/cdrom, but does not start playing. Output is to standard output with each line terminated by a linefeed (LF).

Commands to cdctrl are:

1

[1..99]

?

q

Each command results in one or multiple lines of output to stdout, followed by an info string, followed by END.

The format of the info string is:

CMD cmd-name cd-status track abs-time rel-time

  cmd-name  := {play, stop, ... quit} from above list
  cd-status := {invalid, play, paused}
  cd-status += {completed, error, no_status}
  track     := {1..99} CD track
  abs-time  := HH:MM:SS elapsed since CD start
  rel-time  := HH:MM:SS elapsed since track start

/dev/cdrom - default cdrom device
