'git cherry-pick' [--edit] [-n] [-m parent-number] [-s] [-x] [--ff]
|

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 behaviour, 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
|
|
---------------------

|
|
|
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.
