Git blame committed line
提问by Gustavo Litovsky
Is it possible somehow for GIT to find which commit introduced a specific line of code in a specific file? This is assuming that there have been many commits since that line was added. Or is this something that must be done in a script while looking at the git blame of all the commits for the file in which the line is present?
GIT 是否有可能以某种方式找到哪个提交在特定文件中引入了特定代码行？这是假设自从添加该行以来已经有很多提交。或者这是必须在脚本中完成的事情，同时查看该行所在文件的所有提交的 git blame ？
To clarify
澄清
Original file->Line Added to file and committed -> Many other commits adding other lines and changing the code
原始文件-> 行添加到文件并提交-> 许多其他提交添加其他行并更改代码

You can use git blame -l filenameto get the SHA1 hash from when the line was changed.
您可以使用git blame -l filename从更改行时获取 SHA1 哈希值。
You also can use --reverse:
您也可以使用 --reverse：
--reverse
Walk history forward instead of backward. Instead of showing the revision in which a line appeared, this shows the last revision in which a line has existed. This requires a range of revision like START..END where the path to blame exists in START.
- 逆转
向前而不是向后走历史。这不是显示出现行的修订版，而是显示存在行的最后一个修订版。这需要一系列修订，例如 START..END，其中 START 中存在归咎路径。

It seems you can use git log -L to check file. For example, I want to check the commits for file.c, line from 55 to 60:
看来您可以使用 git log -L 来检查文件。例如，我想检查 file.c 的提交，第 55 到 60 行：
git log -L55,60:file.c

You can blame against the specific code string like this.
您可以像这样指责特定的代码字符串。
git log -S 'THE-CODE'

Assuming that the line hasn't changed since it's been added, then simply:
假设该行自添加以来没有改变，那么只需：
git blame <that file>and then look for the line that you're after.
git blame <that file>然后查找您要查找的行。
If the line has been modified since it's been added, you can still git blameto find out the last commit on which the line was altered, and then git checkout <sha>~1(where shais the sha that shows up in the original git blame) and git blameagain to go back in the history for that line.
如果该行自添加以来已被修改，您仍然git blame可以找出该行被更改的最后一次提交，然后git checkout <sha>~1（sha原始文件中显示的 sha在哪里git blame）并git blame再次返回历史记录那条线。
