c9c2ca27 2.SH NAME
99d009fa 3abcde \- Grab an entire CD and compress it to Ogg/Vorbis, MP3, FLAC, Ogg/Speex and/or MPP/MP+(Musepack) format.
c9c2ca27 4.SH SYNOPSIS
5.B abcde
6.I [options] [tracks]
7.SH DESCRIPTION
8Ordinarily, the process of grabbing the data off a CD and encoding it, then
9tagging or commenting it, is very involved.
10.BR abcde
11is designed to automate this. It will take an entire CD and convert it into
12a compressed audio format - Ogg/Vorbis, MPEG Audio Layer III, Free Lossless
d100b6be 13Audio Codec (FLAC), Ogg/Speex, MPP/MP+(Musepack) and/or M4A (AAC) format(s).
14With one command, it will:
c9c2ca27 15.TP
16.B *
17Do a CDDB query over the Internet to look up your CD or use a locally stored CDDB entry
18.TP
19.B *

ffd57cfc 42.P
43Alternatively,
44.B abcde
45can also grab a CD and turn it into a single FLAC file with an embedded
46cuesheet which can be user later on as a source for other formats, and will be
47treated as if it was the original CD. In a way,
48.B abcde
49can take a compressed backup of your CD collection.
c9c2ca27 50.SH OPTIONS
51.TP
52.B \-1
53Encode the whole CD in a single file. The resulting file uses the CD title
8f9c0102 54for tagging. If the resulting format is a flac file with an embedded cuesheet,
93a69eff 55the file can be used as a source for creating other formats. Use "-1 -o
56flac -a default,cue" for obtaining such a file.
d68ebfff 57.TP
c9c2ca27 58.B \-a [actions]
f7c6d185 59Comma-delimited list of actions to perform. Can be one or more of: cddb, cue,
60read, normalize, encode, tag, move, replaygain, playlist, clean. Normalize and
61encode imply read. Tag implies cddb, read, encode. Move implies cddb, read,
62encode, tag. Replaygain implies cddb, read, encode, tag and move. Playlist
93a69eff 63implies cddb. The default is to do all actions except cue, normalize,
64replaygain and playlist.
c9c2ca27 65.TP
66.B \-b
0709e644 67Enable batch mode normalization. See the BATCHNORM configuration variable.
c9c2ca27 68.TP
6fba8f12 69.B \-B
70Disable batch mode replaygain. It processes file by file to add the replaygain
89d883d6 71information. See the NOBATCHREPLAYGAIN configuration variable.
6fba8f12 72.TP
c9c2ca27 73.B \-c [filename]
74Specifies an additional configuration file to parse. Configuration options
75in this file override those in /etc/abcde.conf or $HOME/.abcde.conf.
76.TP
77.B \-C [discid]
78Allows you to resume a session for
79.I discid
80when you no longer have the CD available (abcde will automatically resume if
81you still have the CD in the drive). You must have already finished at
82least the "read" action during the previous session.
83.TP
1b94d6b7 84.B \-d [devicename | filename]
85CD\-ROM block device that contains audio tracks to be read. Alternatively, a
8f9c0102 86single-track flac file with embedded cuesheet.
c9c2ca27 87.TP
88.B \-D
89Capture debugging information (you'll want to redirect this \- try 'abcde \-D
902>logfile')
91.TP
0709e644 92.B \-e
93Erase information about encoded tracks from the internal status file, to enable
94other encodings if the wav files have been kept.
95.TP
fa421b8b 96.B \-f
97Force the removal of the temporary ABCDETEMPDIR directory, even when we have
98not finished. For example, one can read and encode several formats, including
99\'.ogg\', and later on execute a \'move\' action with only one of the given
100formats. On a normal situation it would erase the rest of those encoded
101formats. In this case, abcde will refuse to execute such command, except if \-f
102is used.
103.TP
0709e644 104.B \-g
105Enable lame's \-\-nogap option. See the NOGAP variable. WARNING: lame's
106\-\-nogap disables the Xing mp3 tag. This tag is required for mp3 players to
107correctly display track lengths when playing variable-bit-rate mp3 files.
108.TP
81bc6204 109.B \-h
110Get help information.
04609998 111.TP
c9c2ca27 112.B \-j [number]
113Start [number] encoder processes at once. Useful for SMP systems. Overrides
114the MAXPROCS configuration variable. Set it to "0" when using distmp3 to avoid
115local encoding processes.
116.TP
117.B \-k
118Keep the wav files after encoding.
119.TP
120.B \-l
121Use the low-diskspace algorithm. See the LOWDISK configuration variable.
122.TP
123.B \-L
124Use a local CDDB repository. See CDDBLOCALDIR variable.
125.TP
81bc6204 126.B \-n
c9c2ca27 127Do not query CDDB database. Create and use a template. Edit the template to
128provide song names, artist(s), ...
129.TP
81bc6204 130.B \-N
c9c2ca27 131Non interactive mode. Do not ask anything from the user. Just go ahead.
132.TP
81bc6204 133.B \-m
c9c2ca27 134Create DOS-style playlists, modifying the resulting one by adding CRLF line
135endings. Some hardware players insist on having those to work.
136.TP
24f444d7 137.B \-o [filetype][:filetypeoptions]
fa421b8b 138Select output type. Can be "vorbis" (or "ogg"), "mp3", "flac", "spx", "mpc",
139"m4a" or "wav". Specify a comma-delimited list of output types to obtain all
140specified types. See the OUTPUTTYPE configuration variable. One can pass
141options to the encoder for a specific filetype on the command line separating
142them with a colon. The options must be escaped with double-quotes.
c9c2ca27 143.TP
144.B \-p
145Pads track numbers with 0\'s.
146.TP
fa421b8b 147.B \-P
148Use Unix PIPES to read and encode in one step. It disables multiple encodings,
149since the WAV audio file is never stored in the disc.
150.TP
93a69eff 151.B \-q [quality]
152Use a pre-defined quality level for the encoding process. Defined as low,
153medium or high. The "medium" value is used to reset the default values if other
154are used in the config file(s).
155.TP
c9c2ca27 156.B \-r [hosts...]
157Remote encode on this comma-delimited list of machines using distmp3. See
158the REMOTEHOSTS configuration variable.
159.TP
f23735e2 160.B \-R
161When CDDBLOCALDIR and CDDBUSELOCAL are defined, search recursively under the
162defined directory for matches of the CDDB entry.
163.TP
411ef0b0 164.B \-s [fields...]
165List, separated by comas, the fields to be shown in the CDDB parsed entries.
166Right now it only uses "year" and "genre".
167.TP
c9c2ca27 168.B \-S [speed]
169Set the speed of the CD drive. Needs CDSPEED and CDSPEEDOPTS set properly
170and both the program and device must support the capability.
171.TP
79e3928b 172.B \-t [number]
173Start the numbering of the tracks at a given number. It only affects the
174filenames and the playlist. Internal (tag) numbering remains the same.
175.TP
176.B \-T [number]
177Same as \-t but changes also the internal (tag) numbering. Keep in mind that
178the default TRACK tag for MP3 is $T/$TRACKS so it is changed to simply $T.
179.TP
f7c6d185 180.B \-U
181Set CDDBPROTO to version 5, so that we retrieve ISO-8859-15 encoded CDDB
182information, and we tag and add comments with Latin1 encoding.
cdbd4cc8 183.TP
c9c2ca27 184.B \-v
185Show the version and exit
186.TP
187.B \-V
188Be a bit more verbose. On slow networks the CDDB requests might give the
8f9c0102 189sensation nothing is happening.
c9c2ca27 190.TP
191.B \-x
192Eject the CD when all tracks have been read. See the EJECTCD configuration
193variable.
194.TP
ffd57cfc 195.B \-X [cue2discid]
196Use an alternative "cue2discid" implementation. The name of the binary must be
197exactly that. abcde comes with an implementation in python under the examples
198directory. The special keyword "builtin" forces the usage of the internal
199(default) implementation in shell script.
200.TP
81bc6204 201.B \-w [comment]
202Add a comment to the tracks ripped from the CD.
203.TP
204.B \-W [number]
205Concatenate CD\'s. It uses the number provided to define a comment "CD #" and
206to modify the numbering of the tracks, starting with "#01".
c9c2ca27 207.TP
fd37d8dd 208.B \-z
209DEBUG mode: it will rip, using cdparanoia, the very first second of each track
210and proceed with the actions requested very quickly, also providing some
211"hidden" information about what happens on the background. CAUTION: IT WILL
212ERASE ANY EXISTING RIPS WITHOUT WARNING!
213.TP
c9c2ca27 214.B [tracks]
215A list of tracks you want abcde to process. If this isn't specified, abcde
216will process the entire CD. Accepts ranges of track numbers -
217"abcde 1-5 7 9" will process tracks 1, 2, 3, 4, 5, 7, and 9.
218.SH OUTPUT
219Each track is, by default, placed in a separate file named after the track
9f659ada 220in a subdirectory named after the artist under the current directory.
c9c2ca27 221This can be modified using the OUTPUTFORMAT and VAOUTPUTFORMAT
9f659ada 222variables in your abcde.conf. Each file is given an extension identifying
fa421b8b 223its compression format, 'vorbis' for '.ogg', '.mp3', '.flac', '.spx', '.mpc', '.aac' or '.wav'.
c9c2ca27 224.SH CONFIGURATION
225abcde sources two configuration files on startup - /etc/abcde.conf and
226$HOME/.abcde.conf, in that order.
227.TP
8f9c0102 228The configuration options stated on those files can be overridden by providing
229the appropriate flags at runtime.
6119aaa1 230.TP
c9c2ca27 231The configuration variables have to be set as follows:
232.TP
233.B VARIABLE=value
c9c2ca27 234Except when "value" needs to be quoted or otherwise interpreted. If other
235variables within "value" are to be expanded upon reading the configuration
236file, then double quotes should be used. If they are only supposed to be
237expanded upon use (for example OUTPUTFORMAT) then single quotes must be used.
238.TP
239All sh escaping/quoting rules apply.
240.TP
241Here is a list of options abcde recognizes:
242.TP
fa421b8b 243.B CDDBMETHOD
244Specifies the method we want to use to retrieve the track information. Two
245values are recognized: "cddb" and "musicbrainz". The "cddb" value needs the
246CDDBURL and HELLOINFO variables described below. The "musicbrainz" value uses
8f9c0102 247Python to establish a conversation with the server for information retrieval.
fa421b8b 248.TP
c9c2ca27 249.B CDDBURL
250Specifies a server to use for CDDB lookups.
251.TP
d100b6be 252.B CDDBPROTO
253Specifies the protocol version used for the CDDB retrieval of results. Version
2546 retrieves CDDB entries in UTF-8 format.
255.TP
81bc6204 256.B HELLOINFO
257Specifies the Hello information to send to the CDDB server. The CDDB
258protocol requires you to send a valid username and hostname each time you
259connect. The format of this is username@hostname.
260.TP
261.B CDDBLOCALDIR
262Specifies a directory where we store a local CDDB repository. The entries must
263be standard CDDB entries, with the filename being the DISCID value. Other
264CD playing and ripping programs (like Grip) store the entries under ~/.cddb
265and we can make use of those entries.
266.TP
f23735e2 267.B CDDBLOCALRECURSIVE
268Specifies if the CDDBLOCALDIR has to be searched recursively trying to find a
269match for the CDDB entry. If a match is found and selected, and CDDBCOPYLOCAL
270is selected, it will be copied to the root of the CDDBLOCALDIR if
271CDDBLOCALPOLICY is "modified" or "new".
272.TP
273.B CDDBLOCALPOLICY
274Defines when a CDDB entry should be stored in the defined CDDBLOCALDIR. The
275possible policies are: "net" for a CDDB entry which has been received from the
276net (overwriting any possible local CDDB entry); "new" for a CDDB entry which
277was received from the net, but will request confirmation to overwrite a local
278CDDB entry found in the root of the CDDBLOCALDIR directory; "modified" for a
279CDDB entry found in the local repository but which has been modified by the
280user; and "always" which forces the CDDB entry to be stored back in the root of
281the CDDBLOCALDIR no matter where it was found, and no matter it was not edited.
282This last option will always overwrite the one found in the root of the local
d100b6be 283repository (if any). STILL NOT WORKING!!
f23735e2 284.TP
81bc6204 285.B CDDBCOPYLOCAL
286Store local copies of the CDDB entries under the $CDDBLOCALDIR directory.
287.TP
288.B CDDBUSELOCAL
8f9c0102 289Actually use the stored copies of the CDDB entries. Can be overridden using the
81bc6204 290"-L" flag (if is CDDBUSELOCAL in "n"). If an entry is found, we always give
291the choice of retrieving a CDDB entry from the internet.
292.TP
9ff5088c 293.B SHOWCDDBFIELDS
294Coma-separated list of fields we want to parse during the CDDB parsing.
295Defaults to "year,genre".
296.TP
c9c2ca27 297.B OGGENCODERSYNTAX
298Specifies the style of encoder to use for the Ogg/Vorbis encoder. Valid options
299are \'oggenc\' (default for Ogg/Vorbis) and \'vorbize\'.
300This affects the default location of the binary,
301the variable to pick encoder command-line options from, and where the options
302are given.
303.TP
304.B MP3ENCODERSYNTAX
305Specifies the style of encoder to use for the MP3 encoder. Valid options are
306\'lame\' (default for MP3), \'gogo\', \'bladeenc\', \'l3enc\' and \'mp3enc\'.
307Affects the same way as explained above for Ogg/Vorbis.
308.TP
309.B FLACENCODERSYNTAX
310Specifies the style of encoder to use for the FLAC encoder. At this point only
311\'flac\' is available for FLAC encoding.
312.TP
313.B SPEEXENCODERSYNTAX
314Specifies the style of encoder to use for Speex encoder. At this point only
315\'speexenc\' is available for Ogg/Speex encoding.
316.TP
99d009fa 317.B MPPENCODERSYNTAX
318Specifies the style of encoder to use for MPP/MP+ (Musepack) encoder. At this
319point we only have \'mppenc\' available, from corecodecs.org.
320.TP
fa421b8b 321.B AACENCODERSYNTAX
322Specifies the style of encoder to use for M4A (AAC) encoder. At this point we
323only support \'faac\', so \'default\' points to it.
324.TP
c9c2ca27 325.B NORMALIZERSYNTAX
326Specifies the style of normalizer to use. Valid options are \'default\'
81bc6204 327and \'normalize'\ (and both run \'normalize-audio\'), since we only support it,
328ATM.
c9c2ca27 329.TP
81bc6204 330.B CDROMREADERSYNTAX
1b94d6b7 331Specifies the style of cdrom reader to use. Valid options are \'cdparanoia\',
332\'debug\' and \'flac\'. It is used for querying the CDROM and obtain a list of
333valid tracks and DATA tracks. The special \'flac\' case is used to "rip" CD
334tracks from a single-track flac file.
c9c2ca27 335.TP
f00ed3e7 336.B CUEREADERSYNTAX
337Specifies the syntax of the program we use to read the CD CUE sheet. Right now
338we only support \'mkcue\', but in the future other readers might be used.
339.TP
81bc6204 340.B KEEPWAVS
341It defaults to no, so if you want to keep those wavs ripped from your CD,
342set it to "y". You can use the "-k" switch in the command line. The default
6fba8f12 343behaviour with KEEPWAVS set is to keep the temporary directory and the wav
81bc6204 344files even you have requested the "clean" action.
c9c2ca27 345.TP
81bc6204 346.B PADTRACKS
347If set to "y", it adds 0's to the file numbers to complete a two-number
65f3ebb1 348holder. Useful when encoding tracks 1-9.
c9c2ca27 349.TP
81bc6204 350.B INTERACTIVE
351Set to "n" if you want to perform automatic rips, without user intervention.
352.TP
353.B NICE VALUES
354Define the values for priorities (nice values) for the different CPU-hungry
355processes: encoding (ENCNICE), CDROM read (READNICE) and distributed encoder
356with distmp3 (DISTMP3NICE).
357.TP
358.B PATHNAMES
359The following configuration file options specify the pathnames of their
c1bbe6c3 360respective utilities: LAME, TOOLAME, GOGO, BLADEENC, L3ENC, XINGMP3ENC, MP3ENC,
fa421b8b 361VORBIZE, OGGENC, FLAC, SPEEXENC, MPPENC, AACEND, ID3, ID3V2, EYED3, METAFLAC,
cb414c1e 362CDPARANOIA, CDDA2WAV, CDDAFS, CDDISCID, CDDBTOOL, EJECT, MD5SUM, DISTMP3,
363VORBISCOMMENT, NORMALIZE, CDSPEED, MP3GAIN, VORBISGAIN, MPPGAIN, MKCUE, MKTOC,
ffd57cfc 364CUE2DISCID (see option "\-X"), DIFF and HTTPGET.
81bc6204 365.TP
366.B COMMAND-LINE OPTIONS
c1bbe6c3 367If you wish to specify command-line options to any of the programs abcde uses,
368set the following configuration file options: LAMEOPTS, TOOLAMEOPTS, GOGOOPTS,
81bc6204 369BLADEENCOPTS, L3ENCOPTS, XINGMP3ENCOPTS, MP3ENCOPTS, VORBIZEOPTS, OGGENCOPTS,
fa421b8b 370FLACOPTS, SPEEXENCOPTS, MPPENCOPTS, AACENCOPTS, ID3OPTS, ID3V2OPTS,
371CDPARANOIAOPTS, CDDA2WAVOPTS, CDDAFSOPTS, CDDBTOOLOPTS, EJECTOPTS, DISTMP3OPTS,
372NORMALIZEOPTS, CDSPEEDOPTS, MKCUEOPTS, VORBISCOMMMENTOPTS, METAFLACOPTS,
373DIFFOPTS and HTTPGETOPTS.
81bc6204 374.TP
375.B CDSPEEDVALUE
376Set the value of the CDROM speed. The default is to read the disc as fast as
377the reading program and the system permits. The steps are defined as 150kB/s
378(1x).
379.TP
380.B ACTIONS
381The default actions to be performed when reading a disc.
382.TP
383.B CDROM
384If set, it points to the CD-Rom device which has to be used for audio
1b94d6b7 385extraction. Abcde tries to guess the right device, but it may fail. The special
386\'flac\' option is defined to extract tracks from a single-track flac file.
c9c2ca27 387.TP
c008b56d 388.B CDPARANOIACDROMBUS
389Defined as "d" when using cdparanoia with an IDE bus and as "g" when using
390cdparanoia with the ide-scsi emulation layer.
391.TP
c9c2ca27 392.B OUTPUTDIR
393Specifies the directory to place completed tracks/playlists in.
394.TP
395.B WAVOUTPUTDIR
396Specifies the temporary directory to store .wav files in. Abcde may use up
397to 700MB of temporary space for each session (although it is rare to use
398over 100MB for a machine that can encode music as fast as it can read it).
399.TP
c9c2ca27 400.B OUTPUTTYPE
401Specifies the encoding format to output, as well as the default extension and
b82e2042 402encoder. Defaults to "vorbis". Valid settings are "vorbis" (or "ogg")
403(Ogg/Vorbis), "mp3" (MPEG-1 Audio Layer III), "flac" (Free Lossless Audio
fa421b8b 404Codec), "spx" (Ogg/Speex), "mpc" (MPP/MP+ (Musepack)), "m4a" (for M4A (AAC)) or
405"wav" (Microsoft Waveform). Values like "vorbis,mp3" encode the tracks in both
406Ogg/Vorbis and MP3 formats.
81bc6204 407.br
c9c2ca27 408For each value in OUTPUTTYPE, abcde expands a different process for encoding,
409tagging and moving, so you can use the format placeholder, OUTPUT, to create
410different subdirectories to hold the different types. The variable OUTPUT will
fa421b8b 411be 'vorbis', 'mp3', 'flac', 'spx', 'mpc', 'm4a' and/or 'wav', depending on the
412OUTPUTTYPE you define. For example
81bc6204 413.br
c9c2ca27 414OUTPUTFORMAT='${OUTPUT}/${ARTISTFILE}/${ALBUMFILE}/${TRACKNUM}._${TRACKFILE}'
415.TP
81bc6204 416.B OUTPUTFORMAT
fa421b8b 417Specifies the format for completed Ogg/Vorbis, MP3, FLAC, Ogg/Speex, MPP/MP+
418(Musepack) or M4A filenames. Variables are included using standard shell
419syntax. Allowed variables are GENRE, ALBUMFILE, ARTISTFILE, TRACKFILE,
420TRACKNUM, and YEAR. Default is \'${ARTISTFILE}-${ALBUMFILE}/${TRACKNUM}-${TRACKFILE}\'.
421Make sure to use single quotes around this variable. TRACKNUM is automatically
422zero-padded, when the number of encoded tracks is higher than 9. When lower,
b8d3298b 423you can force with '-p' in the command line.
81bc6204 424.TP
c9c2ca27 425.B VAOUTPUTFORMAT
ffd57cfc 426Just like OUTPUTFORMAT but for Various Artists discs. The default is 'Various-${ALBUMFILE}/${TRACKNUM}.${ARTISTFILE}-${TRACKFILE}'
427.TP
428.B ONETRACKOUTPUTFORMAT
429Just like OUTPUTFORMAT but for single-track rips (see option "\-1"). The default is '${ARTISTFILE}-${ALBUMFILE}/${ALBUMFILE}'
430.TP
431.B VAONETRACKOUTPUTFORMAT
432Just like ONETRACKOUTPUTFORMAT but for Various Artists discs. The default is 'Various-${ALBUMFILE}/${ALBUMFILE}'
c9c2ca27 433.TP
c9c2ca27 434.B MAXPROCS
435Defines how many encoders to run at once. This makes for huge speedups
436on SMP systems. You should run one encoder per CPU at once for maximum
437efficiency, although more doesn't hurt very much. Set it "0" when using
438mp3dist to avoid getting encoding processes in the local host.
439.TP
440.B LOWDISK
441If set to y, conserves disk space by encoding tracks immediately after
442reading them. This is substantially slower than normal operation but
443requires several hundred MB less space to complete the encoding of an
444entire CD. Use only if your system is low on space and cannot encode as
445quickly as it can read.
446.TP
0709e644 447.B BATCHNORM
c9c2ca27 448If set to y, enables batch mode normalization, which preserves relative
449volume differences between tracks of an album. Also enables nogap encoding
450when using the \'lame\' encoder.
451.TP
0709e644 452.B NOGAP
453Activate the lame's \-\-nogap option, that allows files found in CDs with no
454silence between songs (such as live concerts) to be encoded without noticeable
455gaps. WARNING: lame's \-\-nogap disables the Xing mp3 tag. This tag is
456required for mp3 players to correctly display track lengths when playing
457variable-bit-rate mp3 files.
458.TP
c9c2ca27 459.B PLAYLISTFORMAT
460Specifies the format for completed playlist filenames. Works like the
461OUTPUTFORMAT configuration variable. Default is
462\'${ARTISTFILE}_\-_${ALBUMFILE}.m3u\'.
463Make sure to use single quotes around this variable.
464.TP
465.B PLAYLISTDATAPREFIX
466Specifies a prefix for filenames within a playlist. Useful for http
467playlists, etc.
468.TP
99d009fa 469.B DOSPLAYLIST
470If set, the resulting playlist will have CR-LF line endings, needed by some
471hardware-based players.
472.TP
c9c2ca27 473.B COMMENT
474Specifies a comment to embed in the ID3 or Ogg comment field of each
475finished track. Can be up to 28 characters long. Supports the same
476syntax as OUTPUTFORMAT. Does not currently support ID3v2.
477.TP
478.B REMOTEHOSTS
479Specifies a comma-delimited list of systems to use for remote encoding using
480distmp3. Equivalent to -r.
481.TP
482.B mungefilename
483mungefilename() is an abcde shell function that can be overridden via
484abcde.conf. It takes CDDB data as $1 and outputs the resulting filename on
485stdout. It defaults to eating control characters, apostrophes and
486question marks, translating spaces and forward slashes to underscores, and
487translating colons to an underscore and a hyphen.
488.br
489If you modify this function, it is probably a good idea to keep the forward
490slash munging (UNIX cannot store a file with a '/' char in it) as well as
491the control character munging (NULs can't be in a filename either, and
492newlines and such in filenames are typically not desirable).
493.TP
7acef70b 494.B mungegenre
495mungegenre () is a shell function used to modify the $GENRE variable. As
496a default action, it takes $GENRE as $1 and outputs the resulting value
497to stdout converting all UPPERCASE characters to lowercase.
498.TP
499.B pre_read
500pre_read () is a shell function which is executed before the CDROM is read
501for the first time, during abcde execution. It can be used to close the CDROM
502tray, to set its speed (via "setcd" or via "eject", if available) and other
503preparation actions. The default function is empty.
504.TP
9ff5088c 505.B post_read
506post_read () is a shell function which is executed after the CDROM is read
507(and, if applies, before the CDROM is ejected). It can be used to read a TOC
508from the CDROM, or to try to read the DATA areas from the CD (if any exist).
509The default function is empty.
510.TP
c9c2ca27 511.B EJECTCD
512If set to "y", abcde will call eject(1) to eject the cdrom from the drive
1b94d6b7 513after all tracks have been read. It has no effect when CDROM is set to a flac
514file.
79e3928b 515.TP
516.B EXTRAVERBOSE
517If set to "y", some operations which are usually now shown to the end user
65f3ebb1 518are visible, such as CDDB queries. Useful for initial debug and if your
79e3928b 519network/CDDB server is slow.

523.B abcde
524Will work in most systems
525.TP
0709e644 526.B abcde \-d /dev/cdrom2
8f9c0102 527If the CDROM you are reading from is not the standard /dev/cdrom (in GNU/Linux systems)
24f444d7 528.TP
0709e644 529.B abcde \-o vorbis,flac
24f444d7 530Will create both Ogg/Vorbis and Ogg/FLAC files.
531.TP
0709e644 532.B abcde \-o vorbis:"-b 192"
24f444d7 533Will pass "-b 192" to the Ogg/Vorbis encoder, without having to modify the
534config file
535.TP
0709e644 536.B abcde \-W 1
1b94d6b7 537For double+ CD settings: will create the 1st CD starting with the track number
538101, and will add a comment "CD 1" to the tracks, the second starting with 201
539and so on.
540.TP
541.B abcde \-d singletrack.flac
8f9c0102 542Will extract the files contained in singletrack using the embedded cuesheet.
