git - 如何通过提交消息搜索Git存储库？(How to search a Git repository by commit message?)

Question

I checked some source code into GIT with the commit message "Build 0051".

(我使用提交消息“Build 0051”检查了一些源代码到GIT中。)

However, I can't seem to find that source code any more - how do I extract this source from the GIT repository, using the command line?

(但是，我似乎无法再找到源代码 - 如何使用命令行从GIT存储库中提取此源代码？)

Update

1. Checked in versions 0043, 0044, 0045 and 0046 using SmartGIT.

   (使用SmartGIT检查版本0043,0044,0045和0046。)

2. Checked out 0043, and checked in versions up to 0051 on a different branch.

   (检出0043，并检查其他分支上的版本0051。)

3. Checked out 0043 again.

   (再次检查0043。)

4. Now, 0051 has disappeared.

   (现在，0051已经消失了。)

The source code is definitely there, now its a matter of checking it out:

(源代码肯定存在，现在需要检查它：)

C:Source>git log -g --grep="0052"
commit 77b1f718d19e5cf46e2fab8405a9a0859c9c2889
Reflog: HEAD@{10} (unknown <Mike@.(none)>)

Answer 1

To search the commit log (across all branches) for the given text:

(要搜索给定文本的提交日志（跨所有分支）：)

git log --all --grep='Build 0051'

To search the actual content of commits through a repo's history, use:

(要通过回购历史记录搜索提交的实际内容，请使用：)

git grep 'Build 0051' $(git rev-list --all)

to show all instances of the given text, the containing file name, and the commit sha1.

(显示给定文本的所有实例，包含文件名和提交sha1。)

Finally, as a last resort in case your commit is dangling and not connected to history at all, you can search the reflog itself with the -g flag (short for --walk-reflogs :

(最后，作为最后的手段，如果您的提交悬空并且根本没有连接到历史记录，您可以使用-g标志搜索reflog本身（ --walk-reflogs ：)

git log -g --grep='Build 0051'

EDIT: if you seem to have lost your history, check the reflog as your safety net.

(编辑：如果您似乎丢失了历史记录，请将reflog作为您的安全网。)

Look for Build 0051 in one of the commits listed by

(在列出的其中一个提交中查找Build 0051)

git reflog

You may have simply set your HEAD to a part of history in which the 'Build 0051' commit is not visible, or you may have actually blown it away.

(您可能只是将HEAD设置为历史记录的一部分，其中“Build 0051”提交不可见，或者您可能实际上将其吹走了。)

The git-ready reflog article may be of help.

(git-ready reflog文章可能会有所帮助。)

To recover your commit from the reflog : do a git checkout of the commit you found (and optionally make a new branch or tag of it for reference)

(要从reflog中恢复您的提交 ：执行您找到的提交的git checkout（并可选择创建一个新的分支或标记以供参考）)

git checkout 77b1f718d19e5cf46e2fab8405a9a0859c9c2889
# alternative, using reflog (see git-ready link provided)
# git checkout HEAD@{10}
git checkout -b build_0051 # make a new branch with the build_0051 as the tip
