如何为git rebase选择合并策略？

git-rebase手册页中提到的内容-X<option>可以传递给git-merge。何时/究竟如何？

我想通过应用修补程序与变基递归策略和他们的选项（适用任何棒，而不是跳过整个冲突的提交）。我不想合并，我想使历史线性化。

我试过了：

git rebase -Xtheirs

和

git rebase -s 'recursive -Xtheirs'

但是git -X在两种情况下都拒绝。

git rebase -Xtheirs在最新版本中有效，除了树冲突需要手动解决。解决这些冲突后，您需要运行git rebase -Xtheirs --continue（-X重复）。

您可以在Git v1.7.3或更高版本中使用它。

git rebase --strategy-option theirs ${branch} # Long option
git rebase -X theirs ${branch} # Short option

（这是文档中git rebase --strategy recursive --strategy-option theirs ${branch}所述的缩写）

从Git v1.7.3发行说明：

git rebase --strategy <s>了解了--strategy-option/ -X选项，以传递所选合并策略可以理解的其他选项。

注意：“我们的”和“他们的”是指他们在直接合并期间所做的相反的事情。换句话说，“他们”赞成当前分支上的提交。

这是针对带有各自选项的合并策略

git rebase <branch> -s recursive -X theirs

尽管此补丁提到（2010年2月），但它应该可以工作：

联机帮助页上说它git-rebase支持合并策略，但是rebase命令不了解-X，并给出了用法。

因此，如果仍然无法正常运行，则目前正在辩论中！
（最近的git支持）

来自提交db2b3b820e2b28da268cc88adff076b396392dfe的更新（2013年7月，git 1.8.4+），

不要忽略交互式变基中的合并选项

可以在中指定合并策略及其选项git rebase，但使用-- interactive可以完全忽略它们。

签字人：Arnaud Fontaine

这意味着-X，策略现在可以与交互式rebase以及普通rebase一起使用。

正如iCrazy所说，此功能仅适用于git 1.7.3及更高版本。因此，对于仍然使用1.7.1的可怜的灵魂（像我一样），我提出了自己解决的方案：

git-rebase-他们

这是一个经过精心抛光（因此很长）的脚本，供生产使用：ui选项，处理多个文件，检查文件是否实际具有冲突标记等，但“核心”可以概括为两行：

cp file file.bak
awk '/^<+ HEAD$/,/^=+$/{next} /^>+ /{next} 1' file.bak > file

这是完整的脚本：

    Resolve git rebase conflicts in FILE(s) by favoring 'theirs' version

    When using git rebase, conflicts are usually wanted to be resolved
    by favoring the <working branch> version (the branch being rebased,
    'theirs' side in a rebase), instead of the <upstream> version (the
    base branch, 'ours' side)

    But git rebase --strategy -X theirs is only available from git 1.7.3
    For older versions, $myname is the solution.

    It works by discarding all lines between '<<<<<<< HEAD' and '========'
    inclusive, and also the the '>>>>>> commit' marker.

    By default it outputs to stdout, but files can be edited in-place
    using --in-place, which, unlike sed, creates a backup by default.

    Options:
      -h|--help            show this page.
      -v|--verbose         print more details in stderr.

      --in-place[=SUFFIX]  edit files in place, creating a backup with
                           SUFFIX extension. Default if blank is ""$ext"

       --no-backup         disables backup
