搜索git repo文件的所有版本

Question

我的计算机上有一个文件夹，它是一个git repo。 此文件夹包含一个名为fileA

的文件（还有许多其他文件）

我想在所有（或所有子集）已落实版本str的内容中搜索字符串fileA。

有可能吗？

我不是git方面的专家，我使用SourceTree来管理仓库。

我对任何解决方案都感兴趣。例如，使用GitLab或GitHub的解决方案对我来说很好。

使用SourceTree的解决方案

已给出了通过终端中执行命令的解决方案。

SourceTree是否有解决方案？

请参见grep-all别名：

                && ContextCompat.checkSelfPermission(this, READ_EXTERNAL_STORAGE) != PackageManager.PERMISSION_GRANTED
                ;
    }

    }

别名用grep-all = !"f() { git rev-list --all | xargs git grep \"$@\"; }; f" 列出了所有分支中的所有修订，并在每个修订版上运行git rev-list --all。

要使其适合于抓取一个文件

git grep
