Git冲突中git checkout高级用法是什么

背景

Git冲突的原因，一般是修改了同一个文件导致的，这个文件有可能是别人提交到远程仓库里面，还有就是需要合并这个文件导致的。

解决方法

1. 你确定你需要的是哪个仓库的文件

git checkout --theirs conflicted_file.txt  # 保留远端的
git checkout --ours conflicted_file.txt # 保留本地的

2. 然后执行add和commit

git add -A
git commit -m "update conflict

举个栗子

获取远端服务器上的文件，提示冲突了需要合并

# git cherry-pick FETCH_HEAD
* branch            refs/changes/85/12385/3 -> FETCH_HEAD
error: 'cherry-pick' is not possible because you have unmerged files.
hint: Fix them up in the work tree,
hint: and then use 'git add/rm ' as
hint: appropriate to mark resolution and make a commit,
hint: or use 'git commit -a'.
fatal: cherry-pick failed

查看当前仓库的状态

# git status
Not currently on any branch.
You are currently cherry-picking commit 53e5374.
  (fix conflicts and run "git cherry-pick --continue")
  (use "git cherry-pick --abort" to cancel the cherry-pick operation)

Unmerged paths:
  (use "git add ..." to mark resolution)
     both modified: file1.txt

用提示的命令执行

# git cherry-pick --continue

U   file1.txt

error: 'commit' is not possible because you have unmerged files.
hint: Fix them up in the work tree,
hint: and then use 'git add/rm ' as
hint: appropriate to mark resolution and make a commit,
hint: or use 'git commit -a'.
fatal: Exiting because of an unresolved conflict.

提示file1.txt有更新，确定替换为远程仓库的文件。这里用theirs

git checkout --theirs file1.txt

然后添加到本地仓库

git add -A

最后继续cherry-pick「复制」

# git cherry-pick --continue
[detached HEAD 8f26ce8] Summary : test git checkout --theirs

小结

git ckeckout 和 带参数的--ours和 --theirs还是有区别的。
