你可以在Git仓库中做这件事：
$ b $ pre $ g $ grepstring / regexp$（git rev-list - 所有）

Github高级搜索具有代码搜索功能：

代码搜索将遍历所有公开托管在GitHub上的代码。您也可以按以下方式过滤：

• 语言： language：


• 存储库名称（包括用户名）： repo：


• 文件路径：路径：

Using git, how could I search within all files in all local branches for a given string ?

Github specific : is it possible to perform the above search across all github branches ? (There are several remote branches on my remote github repo that ideally I wouldn't have to bring down for this search..)

You can do this on a Git repo:

git grep "string/regexp" $(git rev-list --all)

Github advanced search has code search capability:

The Code search will look through all of the code publicly hosted on GitHub. You can also filter by:

• the language: language:
• the repository name (including the username): repo:
• the file path: path:
