 'git notes' prune [-n | -v]
 'git notes' get-ref


 DESCRIPTION
 -----------
 Adds, removes, or reads notes attached to objects, without touching
 the objects themselves.

 By default, notes are saved to and read from `refs/notes/commits`, but
 this default can be overridden.  See the OPTIONS, CONFIGURATION, and
 ENVIRONMENT sections below.  If this ref does not exist, it will be
 quietly created when it is first needed to store a note.

 A typical use of notes is to supplement a commit message without
 changing the commit itself. Notes can be shown by 'git log' along with
 the original commit message. To distinguish these notes from the
 message stored in the commit object, the notes are indented like the
 message, after an unindented line saying "Notes (<refname>):" (or
 "Notes:" for `refs/notes/commits`).

 Notes can also be added to patches prepared with `git format-patch` by
 using the `--notes` option. Such notes are added as a patch commentary
 after a three dash separator line.

 To change which notes are shown by 'git log', see the
 "notes.displayRef" configuration in linkgit:git-log[1].

 See the "notes.rewrite.<command>" configuration for a way to carry
 notes across commands that rewrite commits.


 SUBCOMMANDS
 -----------

 list::
 	List the notes object for a given object. If no object is
 	given, show a list of all note objects and the objects they
 	annotate (in the format "<note object> <annotated object>").
 	This is the default subcommand if no subcommand is given.

 add::
 	Add notes for a given object (defaults to HEAD). Abort if the
 	object already has notes (use `-f` to overwrite existing notes).
 	However, if you're using `add` interactively (using an editor
 	to supply the notes contents), then - instead of aborting -
 	the existing notes will be opened in the editor (like the `edit`
 	subcommand).

 copy::
 	Copy the notes for the first object onto the second object.
 	Abort if the second object already has notes, or if the first
 	object has none (use -f to overwrite existing notes to the
 	second object). This subcommand is equivalent to:
 	`git notes add [-f] -C $(git notes list <from-object>) <to-object>`
 +
 In `--stdin` mode, take lines in the format
 +
 ----------
 <from-object> SP <to-object> [ SP <rest> ] LF
 ----------
 +
 on standard input, and copy the notes from each <from-object> to its
 corresponding <to-object>.  (The optional `<rest>` is ignored so that
 the command can read the input given to the `post-rewrite` hook.)

 append::
 	Append to the notes of an existing object (defaults to HEAD).
 	Creates a new notes object if needed.

 edit::
 	Edit the notes for a given object (defaults to HEAD).

 show::
 	Show the notes for a given object (defaults to HEAD).

 merge::
 	Merge the given notes ref into the current notes ref.
 	This will try to merge the changes made by the given
 	notes ref (called "remote") since the merge-base (if
 	any) into the current notes ref (called "local").
 +
 If conflicts arise and a strategy for automatically resolving
 conflicting notes (see the -s/--strategy option) is not given,
 the "manual" resolver is used. This resolver checks out the
 conflicting notes in a special worktree (`.git/NOTES_MERGE_WORKTREE`),
 and instructs the user to manually resolve the conflicts there.
 When done, the user can either finalize the merge with
 'git notes merge --commit', or abort the merge with
 'git notes merge --abort'.

 remove::
 	Remove the notes for given objects (defaults to HEAD). When
 	giving zero or one object from the command line, this is
 	equivalent to specifying an empty note message to
 	the `edit` subcommand.

 prune::
 	Remove all notes for non-existing/unreachable objects.

 get-ref::
 	Print the current notes ref. This provides an easy way to
 	retrieve the current notes ref (e.g. from scripts).

 OPTIONS
 -------
 -f::
 --force::
 	When adding notes to an object that already has notes,
 	overwrite the existing notes (instead of aborting).

 -m <msg>::
 --message=<msg>::
 	Use the given note message (instead of prompting).
 	If multiple `-m` options are given, their values
 	are concatenated as separate paragraphs.
 	Lines starting with `#` and empty lines other than a
 	single line between paragraphs will be stripped out.

 -F <file>::
 --file=<file>::
 	Take the note message from the given file.  Use '-' to
 	read the note message from the standard input.
 	Lines starting with `#` and empty lines other than a
 	single line between paragraphs will be stripped out.

 -C <object>::
 --reuse-message=<object>::
 	Take the given blob object (for	example, another note) as the
 	note message. (Use `git notes copy <object>` instead to
 	copy notes between objects.)

 -c <object>::
 --reedit-message=<object>::
 	Like '-C', but with '-c' the editor is invoked, so that
 	the user can further edit the note message.

 --ref <ref>::
 	Manipulate the notes tree in <ref>.  This overrides
 	'GIT_NOTES_REF' and the "core.notesRef" configuration.  The ref
 	is taken to be in `refs/notes/` if it is not qualified.

 --ignore-missing::
 	Do not consider it an error to request removing notes from an
 	object that does not have notes attached to it.

 --stdin::
 	Also read the object names to remove notes from from the standard
 	input (there is no reason you cannot combine this with object
 	names from the command line).

 -n::
 --dry-run::
 	Do not remove anything; just report the object names whose notes
 	would be removed.

 -s <strategy>::
 --strategy=<strategy>::
 	When merging notes, resolve notes conflicts using the given
 	strategy. The following strategies are recognized: "manual"
 	(default), "ours", "theirs", "union" and "cat_sort_uniq".
 	See the "NOTES MERGE STRATEGIES" section below for more
 	information on each notes merge strategy.

 --commit::
 	Finalize an in-progress 'git notes merge'. Use this option
 	when you have resolved the conflicts that 'git notes merge'
 	stored in .git/NOTES_MERGE_WORKTREE. This amends the partial
 	merge commit created by 'git notes merge' (stored in
 	.git/NOTES_MERGE_PARTIAL) by adding the notes in
 	.git/NOTES_MERGE_WORKTREE. The notes ref stored in the
 	.git/NOTES_MERGE_REF symref is updated to the resulting commit.

 --abort::
 	Abort/reset a in-progress 'git notes merge', i.e. a notes merge
 	with conflicts. This simply removes all files related to the
 	notes merge.

 -q::
 --quiet::
 	When merging notes, operate quietly.

 -v::
 --verbose::
 	When merging notes, be more verbose.
 	When pruning notes, report all object names whose notes are
 	removed.


 DISCUSSION
 ----------

 Commit notes are blobs containing extra information about an object
 (usually information to supplement a commit's message).  These blobs
 are taken from notes refs.  A notes ref is usually a branch which
 contains "files" whose paths are the object names for the objects
 they describe, with some directory separators included for performance
 reasons footnote:[Permitted pathnames have the form
 'ab'`/`'cd'`/`'ef'`/`'...'`/`'abcdef...': a sequence of directory
 names of two hexadecimal digits each followed by a filename with the
 rest of the object ID.].

 Every notes change creates a new commit at the specified notes ref.
 You can therefore inspect the history of the notes by invoking, e.g.,
 `git log -p notes/commits`.  Currently the commit message only records
 which operation triggered the update, and the commit authorship is
 determined according to the usual rules (see linkgit:git-commit[1]).
 These details may change in the future.

 It is also permitted for a notes ref to point directly to a tree
 object, in which case the history of the notes can be read with
 `git log -p -g <refname>`.


 NOTES MERGE STRATEGIES
 ----------------------

 The default notes merge strategy is "manual", which checks out
 conflicting notes in a special work tree for resolving notes conflicts
 (`.git/NOTES_MERGE_WORKTREE`), and instructs the user to resolve the
 conflicts in that work tree.
 When done, the user can either finalize the merge with
 'git notes merge --commit', or abort the merge with
 'git notes merge --abort'.

 "ours" automatically resolves conflicting notes in favor of the local
 version (i.e. the current notes ref).

 "theirs" automatically resolves notes conflicts in favor of the remote
 version (i.e. the given notes ref being merged into the current notes
 ref).

 "union" automatically resolves notes conflicts by concatenating the
 local and remote versions.

 "cat_sort_uniq" is similar to "union", but in addition to concatenating
 the local and remote versions, this strategy also sorts the resulting
 lines, and removes duplicate lines from the result. This is equivalent
 to applying the "cat | sort | uniq" shell pipeline to the local and
 remote versions. This strategy is useful if the notes follow a line-based
 format where one wants to avoid duplicated lines in the merge result.
 Note that if either the local or remote version contain duplicate lines
 prior to the merge, these will also be removed by this notes merge
 strategy.


 EXAMPLES
 --------

 You can use notes to add annotations with information that was not
 available at the time a commit was written.

 ------------
 $ git notes add -m 'Tested-by: Johannes Sixt <j6t@kdbg.org>' 72a144e2
 $ git show -s 72a144e
 [...]
     Signed-off-by: Junio C Hamano <gitster@pobox.com>

 Notes:
     Tested-by: Johannes Sixt <j6t@kdbg.org>
 ------------

 In principle, a note is a regular Git blob, and any kind of
 (non-)format is accepted.  You can binary-safely create notes from
 arbitrary files using 'git hash-object':

 ------------
 $ cc *.c
 $ blob=$(git hash-object -w a.out)
 $ git notes --ref=built add -C "$blob" HEAD
 ------------

 (You cannot simply use `git notes --ref=built add -F a.out HEAD`
 because that is not binary-safe.)
 Of course, it doesn't make much sense to display non-text-format notes
 with 'git log', so if you use such notes, you'll probably need to write
 some special-purpose tools to do something useful with them.


 CONFIGURATION
 -------------

 core.notesRef::
 	Notes ref to read and manipulate instead of
 	`refs/notes/commits`.  Must be an unabbreviated ref name.
 	This setting can be overridden through the environment and
 	command line.

 notes.displayRef::
 	Which ref (or refs, if a glob or specified more than once), in
 	addition to the default set by `core.notesRef` or
 	'GIT_NOTES_REF', to read notes from when showing commit
 	messages with the 'git log' family of commands.
 	This setting can be overridden on the command line or by the
 	'GIT_NOTES_DISPLAY_REF' environment variable.
 	See linkgit:git-log[1].

 notes.rewrite.<command>::
 	When rewriting commits with <command> (currently `amend` or
 	`rebase`), if this variable is `false`, git will not copy
 	notes from the original to the rewritten commit.  Defaults to
 	`true`.  See also "`notes.rewriteRef`" below.
 +
 This setting can be overridden by the 'GIT_NOTES_REWRITE_REF'
 environment variable.

 notes.rewriteMode::
 	When copying notes during a rewrite, what to do if the target
 	commit already has a note.  Must be one of `overwrite`,
 	`concatenate`, and `ignore`.  Defaults to `concatenate`.
 +
 This setting can be overridden with the `GIT_NOTES_REWRITE_MODE`
 environment variable.

 notes.rewriteRef::
 	When copying notes during a rewrite, specifies the (fully
 	qualified) ref whose notes should be copied.  May be a glob,
 	in which case notes in all matching refs will be copied.  You
 	may also specify this configuration several times.
 +
 Does not have a default value; you must configure this variable to
 enable note rewriting.
 +
 Can be overridden with the 'GIT_NOTES_REWRITE_REF' environment variable.


 ENVIRONMENT
 -----------

 'GIT_NOTES_REF'::
 	Which ref to manipulate notes from, instead of `refs/notes/commits`.
 	This overrides the `core.notesRef` setting.

 'GIT_NOTES_DISPLAY_REF'::
 	Colon-delimited list of refs or globs indicating which refs,
 	in addition to the default from `core.notesRef` or
 	'GIT_NOTES_REF', to read notes from when showing commit
 	messages.
 	This overrides the `notes.displayRef` setting.
 +
 A warning will be issued for refs that do not exist, but a glob that
 does not match any refs is silently ignored.

 'GIT_NOTES_REWRITE_MODE'::
 	When copying notes during a rewrite, what to do if the target
 	commit already has a note.
 	Must be one of `overwrite`, `concatenate`, and `ignore`.
 	This overrides the `core.rewriteMode` setting.

 'GIT_NOTES_REWRITE_REF'::
 	When rewriting commits, which notes to copy from the original
 	to the rewritten commit.  Must be a colon-delimited list of
 	refs or globs.
 +
 If not set in the environment, the list of notes to copy depends
 on the `notes.rewrite.<command>` and `notes.rewriteRef` settings.
