NAME
       dcd - play audio	CDs, program CD-ROM as a smart CD player

SYNOPSIS
       dcd [options] [track-list]

DESCRIPTION
       dcd will	help you use your CD-ROM drive as a CD player under Linux.  In
       addition	to merely playing CDs, dcd can also play random	tracks,	accept
       a  pre-programmed list of tracks, and generally do most of the things a
       good portable CD	player is capable of.

OPTIONS
       dir    List a directory of the CD contents (track numbers  and  playing
	      times,  and  track  names	 if  they are available).  This	option
	      causes dcd to exit immediately.

       eject  Open the CD-ROM tray, and	exit immediately. dcd tries to locate,
	      and kill,	other dcd processes that may be	running.

       help   Display a	friendly help message, and exit.

       info   Display one line of information about the	current	CD, like this:
	      Playing track 3 (of 15), length 5:35 (of 77:05)
	      This option causes dcd to	exit immediately.

       pause  Pause or resume the current CD, exiting immediately.

       stop   Stop  the	 CD  currently	in the player. stop makes a reasonable
	      effort to	locate,	and kill, other	dcd processes that may be run-
	      ning.

       version
	      Report the version of dcd	and a brief copyright notice, and exit
	      immediately.

       a      Print the	number of the first track of the  CD  to  stdout,  and
	      exit immediately.	Comes in handy for various shell scripts.

       z      Print the	number of the last track of the	CD to stdout, and exit
	      immediately. Comes in handy for various shell scripts.

       loop   Loop the tracks in the track list, or the	entire CD if no	tracks
	      are specified.  An effort	is made	to locate, and kill, other dcd
	      processes. (Having two copies of dcd running, each with  differ-
	      ent looped track lists, could get	very strange very quickly.)

       quit   Normally,	 dcd  does  everything	it  can	 to get	out of the way
	      quickly, freeing up the console or xterm it  was	launched  from
	      and  allowing  you  to  get  on  with  your day. Specifying quit
	      inhibits this; i.e. dcd will NOT exit until it's done. This lets
	      you  use	dcd  in	 things	 like  combined	CD/MP3 playlists.  dcd
	      attempts to detect unwise	combinations of	 commands  (like  loop
	      and random, which	would effectively create an infinite loop) and
	      nip them in the bud.

       random Play  randomly-selected  tracks  from  the  CD  forever	(until
	      killed), and return to the console immediately. As with loop, an
	      effort is	made to	deal with other	rogue dcd tasks.  This	option
	      may accept a tracklist.

       x      Display  the  CD	Index  discid for the CD, exiting immediately.
	      This isn't often useful by itself, but  might  be	 useful	 in  a
	      script of	some sort.

       back   Go  to  the  previous  track on the CD. If you're	already	on the
	      first track, this	loops around to	the last track.	As  with  many
	      other  options, we attempt to locate and kill other instances of
	      dcd.

       forward
	      Go to the	next track on the CD. If you're	already	 on  the  last
	      track,  this loops around	to the first track. As with many other
	      options, we attempt to locate and	kill other instances of	dcd.

       kill   Kills off	other known instances of dcd. Might  be	 useful	 in  a
	      shell  script, or	just in	case dcd somehow gets carried away and
	      starts doing weird things.

EXAMPLES
       dcd Plays a CD, plain and simple.

       dcd 2  Stars playing a CD from track 2.

       dcd loop
	      Plays the	whole CD, over and over	and over, until	 killed	 (with
	      dcd stop).

       dcd loop	2 4 7
	      Plays tracks 2, 4, and 7,	over and over, in that order.

       dcd random
	      Plays random tracks from the CD, over and	over and over...

       dcd random 1 3 5	7 9 12
	      Randomly	selects	from the tracks	listed,	and plays 'em over and
	      over...

       dcd 4 6 quit
	      Plays tracks 4 and 6, then exits.	(Normally, dcd will return you
	      to  a  shell  prompt immediately;	this option is useful for some
	      scripts, combination MP3/CD playlists, and other cool stuff.)

BUGS
       dcd doesn't make	nearly as many error/sanity checks as  it  could.   It
       assumes	you  know  what	you're doing, so trying	to eject a CD when the
       tray is already open (as	one example) could have	undefined results.  It
       shouldn't do anything truly bad,	but under the terms of the GNU General
       Public License anything it somehow does isn't my	fault.
       dcd unfortunately now requires Internet access to work. Blame the  peo-
       ple  at	MusicBrainz  for  that one. When they discontinued their lean,
       sexy "CD	Index" project in favor	of the current project,	things	got  a
       lot  less  pleasant  for	 everyone  involved (except perhaps for	them).
       Fortunately, broadband access is	rather	more  common  these  days,  so
       hopefully  this isn't as	much of	a problem as it	would have been	a cou-
       ple years back.
