git - 如何搜索 repo 历史？

Question

有一个包含大量提交的 repo 协议(protocol)。我知道我正在寻找的文件的名称和东西(一个字符串，准确地说是一些系数)，但我不知道它在什么提交中。它不再是当前的一个，这是肯定的，前面几个也没有。

*我如何按时间搜索指定文件(或整个存储库中，我不不在乎)，所以它会遍历所有提交直到他找到它？*

对 mercurial 和 git 都感兴趣。目前两者都在使用，我真的不知道这是否适用于其中任何一个。

Mercurial 有 grep命令。来自文档:

hg grep [OPTION]... PATTERN [FILE]...

search for a pattern in specified files and revisions

Search revisions of files for a regular expression.

This command behaves differently than Unix grep. It only accepts
Python/Perl regexps. It searches repository history, not the working
directory. It always prints the revision number in which a match appears.

By default, grep only prints output for the first revision of a file in
which it finds a match. To get it to print every revision that contains a
change in match status ("-" for a match that becomes a non-match, or "+"
for a non-match that becomes a match), use the --all flag.

对于 Git，这个相关问题似乎很相关:
