how to find the commit message by author?

How can I find the commit message by a spec开发者_C百科ific author?

For example, if we are both working on a project and I want to find the line added by another author for the file hello.java.

git blame hello.java

Are you looking for the commit message, or for the specific line changed by the commit?

If you're looking for the message, use git log to see all of the commit messages. If you mean the specific code line, KingCrunch has what you want.
