DESCRIPTION

14       abc2abc is a simple abc checker/re-formatter/transposer.  It will check
15       whether the file given on the command line obeys basic abc syntax.
16
17       If you want to check an abc  tune,  it  is  recommended  that  you  use
18       abc2midi  with  the -c option.  This performs extra checks that abc2abc
19       does not do.
20
21       The output of abc2abc goes to standard output.  Use redirection to save
22       it to a file.
23

OPTIONS

25       -s     Rework  spacing  in the file (which affects how notes are beamed
26              together when the music is printed out). This  option  does  not
27              appear to be working correctly.
28
29       -n X   Reformats the abc file with line breaks every X bars.
30
31       -b     Don't do bar checking.
32
33       -r     Don't do repeat checking.
34
35       -e     Don't report errors.
36
37       -t n   Transpose tune by n semitones. This function will also work with
38              K: none or one of -nokeys or -nokeyf.  If a voice is assigned to
39              channel  10  (drum  channel)  using a %%MIDI channel 10 command,
40              then this voice is never transposed.
41
42
43       -nda   Convert double accidentals in  guitar  chord  to  another  chord
44              though strictly not correct.
45
46       -u     Update  notation;  the older notation + + for chords is replaced
47              by [] and s s for slurs is replaced by ().
48
49       -OCC   Accept the old notation for chord. Normally this is turned  off,
50              since it conflicts with abc draft standard version 2.0 for deco‐
51              rations (eg. +crescendo(+).
52
53       -d     Re-notate the tune with  all  note  lengths  doubled.  The  unit
54              length  specified  by the L: field command is halved (e.g. L:1/8
55              to L:1/16).
56
57       -v     Re-notate the tune with all note lengths halved. The unit length
58              specified  by  the  L:  field  command is doubled (e.g. L:1/8 to
59              L:1/4).
60
61       -ver   Prints version number and exits.
62
63       -V X   For multivoiced abc files (i.e.  contains  V:  field  commands),
64              only voice X is copied.
65
66       -X n   For  a  file containing many tunes, the X: reference numbers are
67              renumbered sequentially starting from number n.
68
69       -nokeys
70              No key signature will be assumed. Instead, sharps  and  naturals
71              will be placed wherever they are needed.
72
73       -nokeyf
74              No  key  signature  will be assumed. Instead, flats and naturals
75              will be placed wherever they are needed.
76
77       -usekey  sf
78              This will force abc2abc to output the notes in the key signature
79              keys[sf]  where  sf specifies the number of flats (-negative) or
80              sharps (+positive) in the key signature. It is a number  between
81              -5 and +5 inclusive.
82
83       * Normally abc2abc will convert the deprecated notation for decorations
84       (eg. !ppp!) to the abc version 2.0 draft standard (eg. +ppp+).  If  you
85       do not wish to change to this standard include the -OCC flag.
