 NAME
 ----
 git-cherry-pick - Apply the changes introduced by some existing commits

 SYNOPSIS
 --------
 [verse]
 'git cherry-pick' [--edit] [-n] [-m parent-number] [-s] [-x] [--ff]
 		  [-S[<keyid>]] <commit>...
 'git cherry-pick' --continue
 'git cherry-pick' --quit
 'git cherry-pick' --abort

 DESCRIPTION
 -----------

 Given one or more existing commits, apply the change each one
 introduces, recording a new commit for each.  This requires your
 working tree to be clean (no modifications from the HEAD commit).

 When it is not obvious how to apply a change, the following
 happens:

 1. The current branch and `HEAD` pointer stay at the last commit
    successfully made.
 2. The `CHERRY_PICK_HEAD` ref is set to point at the commit that
    introduced the change that is difficult to apply.
 3. Paths in which the change applied cleanly are updated both
    in the index file and in your working tree.
 4. For conflicting paths, the index file records up to three
    versions, as described in the "TRUE MERGE" section of
    linkgit:git-merge[1].  The working tree files will include
    a description of the conflict bracketed by the usual
    conflict markers `<<<<<<<` and `>>>>>>>`.
 5. No other modifications are made.

 See linkgit:git-merge[1] for some hints on resolving such
 conflicts.

 OPTIONS
 -------
 <commit>...::
 	Commits to cherry-pick.
 	For a more complete list of ways to spell commits, see
 	linkgit:gitrevisions[7].
 	Sets of commits can be passed but no traversal is done by
 	default, as if the '--no-walk' option was specified, see
 	linkgit:git-rev-list[1]. Note that specifying a range will
 	feed all <commit>... arguments to a single revision walk
 	(see a later example that uses 'maint master..next').

 -e::
 --edit::
 	With this option, 'git cherry-pick' will let you edit the commit
 	message prior to committing.

 -x::
 	When recording the commit, append a line that says
 	"(cherry picked from commit ...)" to the original commit
 	message in order to indicate which commit this change was
 	cherry-picked from.  This is done only for cherry
 	picks without conflicts.  Do not use this option if
 	you are cherry-picking from your private branch because
 	the information is useless to the recipient.  If on the
 	other hand you are cherry-picking between two publicly
 	visible branches (e.g. backporting a fix to a
 	maintenance branch for an older release from a
 	development branch), adding this information can be
 	useful.

 -r::
 	It used to be that the command defaulted to do `-x`
 	described above, and `-r` was to disable it.  Now the
 	default is not to do `-x` so this option is a no-op.

 -m parent-number::
 --mainline parent-number::
 	Usually you cannot cherry-pick a merge because you do not know which
 	side of the merge should be considered the mainline.  This
 	option specifies the parent number (starting from 1) of
 	the mainline and allows cherry-pick to replay the change
 	relative to the specified parent.

 -n::
 --no-commit::
 	Usually the command automatically creates a sequence of commits.
 	This flag applies the changes necessary to cherry-pick
 	each named commit to your working tree and the index,
 	without making any commit.  In addition, when this
 	option is used, your index does not have to match the
 	HEAD commit.  The cherry-pick is done against the
 	beginning state of your index.
 +
 This is useful when cherry-picking more than one commits'
 effect to your index in a row.

 -s::
 --signoff::
 	Add Signed-off-by line at the end of the commit message.
 	See the signoff option in linkgit:git-commit[1] for more information.

 -S[<keyid>]::
 --gpg-sign[=<keyid>]::
 	GPG-sign commits. The `keyid` argument is optional and
 	defaults to the committer identity; if specified, it must be
 	stuck to the option without a space.

 --ff::
 	If the current HEAD is the same as the parent of the
 	cherry-pick'ed commit, then a fast forward to this commit will
 	be performed.

 --allow-empty::
 	By default, cherry-picking an empty commit will fail,
 	indicating that an explicit invocation of `git commit
 	--allow-empty` is required. This option overrides that
 	behavior, allowing empty commits to be preserved automatically
 	in a cherry-pick. Note that when "--ff" is in effect, empty
 	commits that meet the "fast-forward" requirement will be kept
 	even without this option.  Note also, that use of this option only
 	keeps commits that were initially empty (i.e. the commit recorded the
 	same tree as its parent).  Commits which are made empty due to a
 	previous commit are dropped.  To force the inclusion of those commits
 	use `--keep-redundant-commits`.

 --allow-empty-message::
 	By default, cherry-picking a commit with an empty message will fail.
 	This option overrides that behavior, allowing commits with empty
 	messages to be cherry picked.

 --keep-redundant-commits::
 	If a commit being cherry picked duplicates a commit already in the
 	current history, it will become empty.  By default these
 	redundant commits cause `cherry-pick` to stop so the user can
 	examine the commit. This option overrides that behavior and
 	creates an empty commit object.  Implies `--allow-empty`.

 --strategy=<strategy>::
 	Use the given merge strategy.  Should only be used once.
 	See the MERGE STRATEGIES section in linkgit:git-merge[1]
 	for details.

 -X<option>::
 --strategy-option=<option>::
 	Pass the merge strategy-specific option through to the
 	merge strategy.  See linkgit:git-merge[1] for details.

 SEQUENCER SUBCOMMANDS
 ---------------------
 include::sequencer.txt[]

 EXAMPLES
 --------
 `git cherry-pick master`::

 	Apply the change introduced by the commit at the tip of the
 	master branch and create a new commit with this change.

 `git cherry-pick ..master`::
 `git cherry-pick ^HEAD master`::

 	Apply the changes introduced by all commits that are ancestors
 	of master but not of HEAD to produce new commits.

 `git cherry-pick maint next ^master`::
 `git cherry-pick maint master..next`::

 	Apply the changes introduced by all commits that are
 	ancestors of maint or next, but not master or any of its
 	ancestors.  Note that the latter does not mean `maint` and
 	everything between `master` and `next`; specifically,
 	`maint` will not be used if it is included in `master`.

 `git cherry-pick master~4 master~2`::

 	Apply the changes introduced by the fifth and third last
 	commits pointed to by master and create 2 new commits with
 	these changes.

 `git cherry-pick -n master~1 next`::

 	Apply to the working tree and the index the changes introduced
 	by the second last commit pointed to by master and by the last
 	commit pointed to by next, but do not create any commit with
 	these changes.

 `git cherry-pick --ff ..next`::

 	If history is linear and HEAD is an ancestor of next, update
 	the working tree and advance the HEAD pointer to match next.
 	Otherwise, apply the changes introduced by those commits that
 	are in next but not HEAD to the current branch, creating a new
 	commit for each new change.

 `git rev-list --reverse master -- README | git cherry-pick -n --stdin`::

 	Apply the changes introduced by all commits on the master
 	branch that touched README to the working tree and index,
 	so the result can be inspected and made into a single new
 	commit if suitable.

 The following sequence attempts to backport a patch, bails out because
 the code the patch applies to has changed too much, and then tries
 again, this time exercising more care about matching up context lines.

 ------------
 $ git cherry-pick topic^             <1>
 $ git diff                           <2>
 $ git reset --merge ORIG_HEAD        <3>
 $ git cherry-pick -Xpatience topic^  <4>
 ------------
 <1> apply the change that would be shown by `git show topic^`.
 In this example, the patch does not apply cleanly, so
 information about the conflict is written to the index and
 working tree and no new commit results.
 <2> summarize changes to be reconciled
 <3> cancel the cherry-pick.  In other words, return to the
 pre-cherry-pick state, preserving any local modifications you had in
 the working tree.
 <4> try to apply the change introduced by `topic^` again,
 spending extra time to avoid mistakes based on incorrectly matching
 context lines.
