这让我感到困惑：通常git rebase HEAD^^^^^^^简单地指出：
当前分支测试是最新的。
但是，今天，我向同事演示git rebase -i，我首先做了git rebase 63c1e126，其中63c1e126是从提交日志中选择的提交，并且重新设置因冲突而失败。怎么会这样？
进行rebase -i的原因是为了解决一个问题，即在其他rebase / force push混乱（我想）之后两次应用了相同的提交，并且rebase在应用的第一次提交上发生了冲突。第二次（具有不同的提交哈希和一些空白更改）。
git的输出：
$ git rebase 63c1e126

Resolve all conflicts manually, mark them as resolved with
"git add/rm <conflicted_files>", then run "git rebase --continue".
You can instead skip this commit: run "git rebase --skip".
To abort and get back to the state before "git rebase", run "git rebase --abort".
git log给出类似（替换的提交哈希）：

git log对您说谎并显示线性历史记录。 Git历史不是线性的，分支和合并实际上就是那样。 git log --graph显示真实的历史记录。您的历史已合并。这意味着您的提交历史看起来像这样。
63c1e126 - B - C - I - G - H - K [github/1381_bak]
\ /
D - E - F
git rebase，默认情况下，将删除合并提交并展平您的历史记录。像这样的东西。
63c1e126 - B - D1 - C1 - E1 - I1 - F1 - G1 - H1 - K1 [github/1381_bak]
注意分支的提交现在如何交错。这可能会导致冲突，因为E不是写在C之上。
[如果我们查看重新排列的顺序，我们可以在Added monthly index-file and stations rtf to gitignore之后看到交错的提交。 Initial clean-up和Reformat using Eclipse formatting rules最初都写在Added monthly index-file and stations rtf to gitignore的顶部。但是，重新设置将Reformat using Eclipse formatting rules放在Initial clean-up之上。第二个Initial clean-up也有类似的问题。
$ git rebase 63c1e126

Applying: Cherrypicking python files to commit to master

注意，如果您使用的是新的git rebase -r或--rebase-merges，Git将尝试保留分支并重新创建合并。除非您明确想弄平历史记录，否则请使用-r。
