本文翻译自：Search all of Git history for a string? [duplicate]

I have a code base which I want to push to GitHub as open source. 我有一个代码库，我想将其作为开源推送到GitHub。 In this git-controlled source tree, I have certain configuration files which contain passwords. 在这个git控制的源代码树中，我有一些包含密码的配置文件。 I made sure not to track this file and I also added it to the .gitignore file. 我确保不跟踪此文件，我还将其添加到.gitignore文件中。 However, I want to be absolutely positive that no sensitive information is going to be pushed, perhaps if something slipped in-between commits or something. 但是，我希望绝对肯定的是，没有任何敏感信息会被推送，也许是因为某些事情在提交之间滑落了。 I doubt I was careless enough to do this, but I want to be positive . 我怀疑我做得不够粗心，但我想要积极 。

Is there a way to "grep" all of git? 有没有办法“grep”所有的git？ I know that sounds weird, but by "all" I mean every version of every file that ever existed. 我知道这听起来很奇怪，但“全部”我的意思是每个文件的每个版本都存在。 I guess if there is a command that dumps the diff file for every commit, that might work? 我想如果有一个命令为每次提交转储diff文件，那可能有用吗？

Try the following commands to search the string inside all previous tracked files: 尝试使用以下命令搜索所有先前跟踪文件中的字符串：

git log --patch  | less +/searching_string

or 要么

git rev-list --all | GIT_PAGER=cat xargs git grep 'search_string'

which needs to be run from the parent directory where you'd like to do the searching. 需要从您要进行搜索的父目录运行。

git rev-list --all | (
    while read revision; do
        git grep -F 'password' $revision
    done
)

Git can search diffs with the -S option (it's called pickaxe in the docs ) Git可以使用-S选项搜索差异（ 在文档中称为pickaxe）

git log -Spassword

This will find any commit that added or removed the string password . 这将找到添加或删除字符串password任何提交。 Here a few options: 这里有几个选择：

• -p : will show the diffs. -p ：将显示差异。 If you provide a file ( -p file ), it will generate a patch for you. 如果您提供文件（ -p file ），它将为您生成一个补丁。
• -G : looks for differences whose added or removed line matches the given regexp, as opposed to -S , which "looks for differences that introduce or remove an instance of string". -G ：查找添加或删除的行与给定的正则表达式匹配的差异，而不是-S ，“查找引入或删除字符串实例的差异”。
• --all : searches over all branches and tags; --all ：搜索所有分支和标签; alternatively, use --branches[=<pattern>] or --tags[=<pattern>] 或者，使用--branches[=<pattern>]或--tags[=<pattern>]
