  21DESCRIPTION
  22-----------
  23This command allows you to add/remove notes to/from objects, without
  24changing the objects themselves.
  25
  26A typical use of notes is to extend a commit message without having
  27to change the commit itself. Such commit notes can be shown by `git log`
  28along with the original commit message. To discern these notes from the
  29message stored in the commit object, the notes are indented like the
  30message, after an unindented line saying "Notes (<refname>):" (or
  31"Notes:" for `refs/notes/commits`).
  32
  33This command always manipulates the notes specified in "core.notesRef"
  34(see linkgit:git-config[1]), which can be overridden by GIT_NOTES_REF.
  35To change which notes are shown by 'git-log', see the
  36"notes.displayRef" configuration.
  37
  38See the description of "notes.rewrite.<command>" in
  39linkgit:git-config[1] for a way of carrying your notes across commands
  40that rewrite commits.

  43SUBCOMMANDS
  44-----------
  45
  46list::
  47        List the notes object for a given object. If no object is
  48        given, show a list of all note objects and the objects they
  49        annotate (in the format "<note object> <annotated object>").
  50        This is the default subcommand if no subcommand is given.
  51
  52add::
  53        Add notes for a given object (defaults to HEAD). Abort if the
  54        object already has notes (use `-f` to overwrite an
  55        existing note).
  56
  57copy::
  58        Copy the notes for the first object onto the second object.
  59        Abort if the second object already has notes, or if the first
  60        object has none (use -f to overwrite existing notes to the
  61        second object). This subcommand is equivalent to:
  62        `git notes add [-f] -C $(git notes list <from-object>) <to-object>`
  63+
  64In `\--stdin` mode, take lines in the format
  65+
  66----------
  67<from-object> SP <to-object> [ SP <rest> ] LF
  68----------
  69+
  70on standard input, and copy the notes from each <from-object> to its
  71corresponding <to-object>.  (The optional `<rest>` is ignored so that
  72the command can read the input given to the `post-rewrite` hook.)
  73
  74append::
  75        Append to the notes of an existing object (defaults to HEAD).
  76        Creates a new notes object if needed.
  77
  78edit::
  79        Edit the notes for a given object (defaults to HEAD).
  80
  81show::
  82        Show the notes for a given object (defaults to HEAD).
  83
  84remove::
  85        Remove the notes for a given object (defaults to HEAD).
  86        This is equivalent to specifying an empty note message to
  87        the `edit` subcommand.
  88
  89prune::
  90        Remove all notes for non-existing/unreachable objects.
  91
  92OPTIONS
  93-------
  94-f::
  95--force::
  96        When adding notes to an object that already has notes,
  97        overwrite the existing notes (instead of aborting).
  98
  99-m <msg>::
 100--message=<msg>::
 101        Use the given note message (instead of prompting).
 102        If multiple `-m` options are given, their values
 103        are concatenated as separate paragraphs.
 104        Lines starting with `#` and empty lines other than a
 105        single line between paragraphs will be stripped out.
 106
 107-F <file>::
 108--file=<file>::
 109        Take the note message from the given file.  Use '-' to
 110        read the note message from the standard input.
 111        Lines starting with `#` and empty lines other than a
 112        single line between paragraphs will be stripped out.
 113
 114-C <object>::
 115--reuse-message=<object>::
 116        Take the note message from the given blob object (for
 117        example, another note).
 118
 119-c <object>::
 120--reedit-message=<object>::
 121        Like '-C', but with '-c' the editor is invoked, so that
 122        the user can further edit the note message.
 123
 124--ref <ref>::
 125        Manipulate the notes tree in <ref>.  This overrides both
 126        GIT_NOTES_REF and the "core.notesRef" configuration.  The ref
 127        is taken to be in `refs/notes/` if it is not qualified.
 128

 130DISCUSSION
 131----------
 132
 133Commit notes are blobs containing extra information about an object
 134(usually information to supplement a commit's message).  These blobs
 135are taken from notes refs.  A notes ref is usually a branch which
 136contains "files" whose paths are the object names for the objects
 137they describe, with some directory separators included for performance
 138reasons footnote:[Permitted pathnames have the form
 139'ab'`/`'cd'`/`'ef'`/`'...'`/`'abcdef...': a sequence of directory
 140names of two hexadecimal digits each followed by a filename with the
 141rest of the object ID.].
 142
 143Every notes change creates a new commit at the specified notes ref.
 144You can therefore inspect the history of the notes by invoking, e.g.,
 145`git log -p notes/commits`.  Currently the commit message only records
 146which operation triggered the update, and the commit authorship is
 147determined according to the usual rules (see linkgit:git-commit[1]).
 148These details may change in the future.
 149
 150It is also permitted for a notes ref to point directly to a tree
 151object, in which case the history of the notes can be read with
 152`git log -p -g <refname>`.
 153
 154
 155EXAMPLES
 156--------
 157
 158You can use notes to add annotations with information that was not
 159available at the time a commit was written.

 169------------
 170
 171In principle, a note is a regular Git blob, and any kind of
 172(non-)format is accepted.  You can binary-safely create notes from
 173arbitrary files using 'git hash-object':
 174
 175------------
 176$ cc *.c
 177$ blob=$(git hash-object -w a.out)
 178$ git notes --ref=built add -C "$blob" HEAD
 179------------
 180
 181Of course, it doesn't make much sense to display non-text-format notes
 182with 'git log', so if you use such notes, you'll probably need to write
 183some special-purpose tools to do something useful with them.
