Run git blameon the file. It'll show you the commit ID, the date and time, and who committed it- for each line. Then just copy out the commit identifier and you can use it in git log <commit>or git show <commit>.
git blame在文件上运行。它会向您显示每行的提交 ID、日期和时间以及提交者。然后只需复制提交标识符，您就可以在git log <commit>or 中使用它git show <commit>。
For example, I've got a file, called test.txt, with lines added on different commits:
例如，我有一个名为 test.txt 的文件，在不同的提交中添加了几行：
$ cat test.txt
First line.
Second line.
Running the git blame:
运行git blame：
$ git blame test.txt
^410c3dd (Leigh 2013-11-09 12:00:00 1) First line.
2365eb7d (Leigh 2013-11-09 12:00:10 2) Second line.
The first bit is the commit ID, then name, then date, time, time zone, and finally the line number and line contents.
第一位是提交 ID，然后是名称，然后是日期、时间、时区，最后是行号和行内容。

There is something quicker than issuing a blame on the full file. If the line is ${lineno}and the file is ${filename}you can:
有比对完整文件发出责备更快的事情。如果行是${lineno}并且文件是，${filename}您可以：
git blame -L ${lineno},${lineno} ${filename}
Example:
例子：
git blame -L 2,2 test.txt

git log -S "mention here line of code" [file-path]
For example:
例如：
git log -S "First line" test.txt
Providing the file name with its path is obvious because, most of the time, we want to know who introduced a particular code segment in a particular file.
提供文件名及其路径是显而易见的，因为大多数时候，我们想知道谁在特定文件中引入了特定代码段。
