我们知道在存储库中的一个特定mercurial提交中使用的关键字。但是我们不知道提交的是什么。显然我可以浏览每个提交的文件并最终找到关键字及其使用方式，但这将是一项繁琐的工作。
有没有办法在mercurial中搜索存储库中所有已提交代码的字符串？

hg grep正是如此。
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.
Returns 0 if a match is found, 1 otherwise.
