问题：
I have a Git repository and I'd like to see how some files looked a few months ago. 我有一个Git存储库，我想看看几个月前某些文件的外观。 I found the revision at that date, and it's 27cf8e84bb88e24ae4b4b3df2b77aab91a3735d8 . 我在那个日期找到了修订版本，它是27cf8e84bb88e24ae4b4b3df2b77aab91a3735d8 。 I need to see what did one file looks like and also save that to a file. 我需要查看一个文件的外观，并将其保存到文件中。
I managed to see the file using gitk , but it doesn't have an option to save it. 我设法使用gitk来查看文件，但是它没有保存文件的选项。 I tried with command-line tools, the closest I got was: 我尝试使用命令行工具，但最接近的是：
git-show 27cf8e84bb88e24ae4b4b3df2b77aab91a3735d8 my_file.txt
However, this command shows a diff and not the file contents. 但是，此命令显示差异而不显示文件内容。 I know I can later use something like PAGER=cat and redirect output to a file, but I don't know how to get to the actual file content. 我知道以后可以使用PAGER=cat类的东西并将输出重定向到文件，但是我不知道如何获取实际的文件内容。
Basically, I'm looking for something like svn cat . 基本上，我正在寻找svn cat之类的东西。
