  23 Options:
  24 -1     Encode the whole CD in a single file
  25 -a <action1[,action2]...>
  26        Actions to perform:
  27        cddb,read,normalize,encode,tag,move,replaygain,playlist,clean
  28 -b     Enable batch normalization
  29 -c <file>
  30        Specify a configuration file (overrides system and user config files)
  31 -C <discid#>
  32        Specify discid to resume from (only needed if you no longer have the cd)
  33 -d <device>
  34        Specify CDROM device to grab (flac uses a single-track flac file)
  35 -D     Debugging mode (equivalent to sh -x abcde)
  36 -e     Erase encoded track information from status file
  37 -f     Force operations that otherwise are considered harmful. Read "man abcde"
  38 -g     Use "lame --nogap" for MP3 encoding. Disables low disk and pipes flags
  39 -h     This help information
  40 #-i    Tag files while encoding, when possible (local only) -NWY-
  41 -j <#> Number of encoder processes to run at once (localhost)
  42 -k     Keep the wav tracks for later use
  43 -l     Use low disk space algorithm
  44 -L     Use local CDDB storage directory
  45 -n     No lookup. Don't query CDDB, just create and use template
  46 -N     Noninteractive. Never prompt for anything
  47 -m     Modify playlist to include CRLF endings, to comply with some players
  48        WARNING: Deprecated. Use \"cue\" action
  49 -o <type1[,type2]...>
  50        Output file type(s) (vorbis,mp3,flac,spx,mpc,wav,m4a). Defaults to vorbis
  51 -p     Pad track numbers with 0's (if less than 10 tracks)
  52 -P     Use UNIX pipes to read+encode without wav files
  53 -q <level>
  54        Set quality level (high,medium,low)
  55 -r <host1[,host2]...>
  56        Also encode on these remote hosts
  57 -R     Use local CDDB in recursive mode
  58 -s <field>
  59        Show dielfs from the CDDB info (year,genre)
  60 -S <#> Set the CD speed
  61 -t <#> Start the track numbering at a given number
  62 -T <#> Same as -t but modifies tag numbering
  63 -U     Do NOT use UNICODE (UTF8) tags and comments
  64 -v     Show version number and exit
  65 -V     Be a bit more verbose about what is happening behind the scenes
  66 -x     Eject CD after all tracks are read
  67 -w <comment>
  68        Add a comment to the CD tracks
  69 -W <#> Contatenate CDs: -T #01 -w "CD #"
  70 -z     Use debug CDROMREADERSYNTAX option (needs cdparanoia)
  71
  72 Tracks is a space-delimited list of tracks to grab.
  73 Ranges specified with hyphens are allowed (i.e., 1-5).
