灵感来自答案https://stackoverflow.com/a/2929502/6041515，我发现gitgrep似乎在每次提交时都会搜索完整的代码库，而不仅仅是差异，结果往往重复且冗长。下面的脚本将只搜索每个git提交的差异：

for commit in $(git rev-list --all); do 
    # search only lines starting with + or -
    if  git show "$commit" | grep "^[+|-].*search-string"; then 
        git show --no-patch --pretty=format:'%C(yellow)%h %Cred%ad %Cblue%an%Cgreen%d %Creset%s' --date=short $commit
    fi  
done

示例输出，底部的gitcommit是第一次引入我正在搜索的更改的gitcommit:

csshx$ for commit in $(git rev-list --all); do 
>     if  git show "$commit" | grep "^[+|-].*As csshX is a command line tool"; then 
>         git show --no-patch --pretty=format:'%C(yellow)%h %Cred%ad %Cblue%an%Cgreen%d %Creset%s' --date=short $commit
>     fi  
> done

为现有答案添加更多内容。如果您知道您可能制作的文件，请执行以下操作：

git log --follow -p -S 'search-string' <file-path>

--如下：列出文件的历史记录

为了简单起见，我建议使用GUI:gitk——Git存储库浏览器。它很灵活

要搜索代码：要搜索文件，请执行以下操作：当然，它还支持正则表达式：

您可以使用向上/向下箭头浏览结果。

Jeet的答案在PowerShell中有效。

git grep -n <regex> $(git rev-list --all)

下面显示了任何提交中包含密码的所有文件。

# Store intermediate result
$result = git grep -n "password" $(git rev-list --all)

# Display unique file names
$result | select -unique { $_ -replace "(^.*?:)|(:.*)", "" }

如果您想浏览代码更改（查看整个历史中给定单词的实际更改），请选择补丁模式-我发现了一个非常有用的组合：

git log -p
# Hit '/' for search mode.
# Type in the word you are searching.
# If the first search is not relevant, hit 'n' for next (like in Vim ;) )
