git log

直接在项目目录下敲git log,会看到提交的日志，每一条如下：

$git log

commit 438bcd38d006f307e188c17e89ae36a5c425133a
Author: shuchen <csfreebird@esri.com>
Date:   Wed Sep 5 13:36:32 2012 +0800

    delete lian.1

commit id ，作者，时间日期，提交的时候写的注释。

--pretty参数

用来指定日志的输出格式：

如果用--pretty=fuller参数，会多一个AuthorDate信息。

$git log --pretty=fuller

commit 438bcd38d006f307e188c17e89ae36a5c425133a
Author:     shuchen <csfreebird@esri.com>
AuthorDate: Wed Sep 5 13:36:32 2012 +0800
Commit:     shuchen <csfreebird@esri.com>
CommitDate: Wed Sep 5 13:36:32 2012 +0800

    delete lian.1

精简格式

git log --pretty=oneline

原始格式

git log --pretty=raw

chenshu@sloop2:~/work/189/master$ git log --pretty=raw
commit cb10bb5b02efec6f12e36c9bf6057da0c3ff5a56

committer wangxd555 <wangxd555@esri.com> 1353403586 +0800

可以看到commit id, 属于哪个tree对象，以及前一个commit对象的信息。

检查commit链表
