How to search a Git repository by commit message?
提问by Contango
I checked some source code into GIT with the commit message "Build 0051".
我使用提交消息“Build 0051”将一些源代码检查到 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，我似乎再也找不到该源代码了 - 如何使用命令行从 GIT 存储库中提取此源代码？
Update
更新
- Checked in versions 0043, 0044, 0045 and 0046 using SmartGIT.
- Checked out 0043, and checked in versions up to 0051 on a different branch.
- Checked out 0043 again.
- Now, 0051 has disappeared.
- 使用 SmartGIT 检入版本 0043、0044、0045 和 0046。
- 检出 0043，并检入不同分支上高达 0051 的版本。
- 再次检查了0043。
- 现在，0051已经消失了。

The source code is definitely there, now its a matter of checking it out:
源代码肯定在那里，现在是检查出来的问题：
C:\Source>git log -g --grep="0052"
commit 77b1f718d19e5cf46e2fab8405a9a0859c9c2889
Reflog: HEAD@{10} (unknown <Mike@.(none)>)

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:
要通过存储库的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、包含的文件名和提交 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 -gflag (short for --walk-reflogs:
最后，作为万一您的提交悬而未决并且根本没有连接到历史记录的最后手段，您可以使用-g标志搜索引用日志本身（缩写为--walk-reflogs：
git log -g --grep='Build 0051'
EDIT: if you seem to have lost your history, check the reflogas your safety net. Look for Build 0051 in one of the commits listed by
编辑：如果您似乎丢失了历史记录，请检查reflog作为您的安全网。在列出的提交之一中查找 Build 0051
git reflog
You may have simply set your HEADto a part of history in which the 'Build 0051' commit is not visible, or you may have actually blown it away. The git-ready reflogarticle may be of help.
您可能只是将您HEAD的历史设置为“Build 0051”提交不可见的一部分，或者您实际上可能已经将其吹走了。该混帐就绪引用日志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 恢复您的提交：对您找到的提交进行 git checkout（并可选择为其创建一个新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

I put this in my ~/.gitconfig:
我把它放在我的 ~/.gitconfig 中：
[alias]
find = log --pretty=\"format:%Cgreen%H %Cblue%s\" --name-status --grep
Then I can type "git find string" and I get a list of all the commits containing that string in the message. For example, to find all commits referencing ticket #33:
然后我可以输入“git find string”，然后我会得到一个包含消息中包含该字符串的所有提交的列表。例如，要查找引用票证 #33 的所有提交：

Though a bit late, there is :/which is the dedicated notation to specify a commit (or revision) based on the commit message, just prefix the search string with :/, e.g.:
虽然有点晚了，但有:/专用的符号来根据提交消息指定提交（或修订），只需在搜索字符串前加上:/，例如：
git show :/message
Here <message>can be a complex regex pattern consisting of whitespaces, so please make sure to quote/escape when necessary, e.g.:
这里<message>可能是一个由空格组成的复杂正则表达式模式，因此请确保在必要时引用/转义，例如：
git log -1 -p ":/a few words"
Alternatively, a start point can be specified, to find the closest commit reachable from a specific point, e.g.:
或者，可以指定起点，以找到从特定点可到达的最近提交，例如：
git show 'HEAD^{/fix nasty bug}'
See: git revisions manual.

git log --grep=<pattern>
Limit the commits output to ones with log message that matches the
specified pattern (regular expression).

If the change is not too old, you can do,
如果变化不是太旧，你可以这样做，
