git blame可以显示该文件的修改、以及作者上次修改文件的内容。他不会告诉我们文件中被删除以及被替换的内容，要详细的知道，我们还需要配合git diff的使用。
下面是我们在git中创建了一个aa文件，然后是三次commit提交，以及只属于工作目录的修改。
我们用git blame来查看一下效果：
$git blame aa ^2cae297 (xin 2013-06-02 17:56:14 +0800 1) The beginning is to learn git blame ^2cae297 (xin 2013-06-02 17:56:14 +0800 2) the second to add some difference. ^2cae297 (xin 2013-06-02 17:56:14 +0800 3) ok, let's go ,you can do it ! aba91773 (xin 2013-06-02 17:58:26 +0800 4) aba91773 (xin 2013-06-02 17:58:26 +0800 5) aba91773 (xin 2013-06-02 17:58:26 +0800 6) aba91773 (xin 2013-06-02 17:58:26 +0800 7) After first commit ,I want to add some charater to test git blame 9db59f5a (xin 2013-06-02 18:09:21 +0800 8) 9db59f5a (xin 2013-06-02 18:09:21 +0800 9) 9db59f5a (xin 2013-06-02 18:09:21 +0800 10) 9db59f5a (xin 2013-06-02 18:09:21 +0800 11) This is the third commit ,for testing -b option 00000000 (Not Committed Yet 2013-06-02 18:25:21 +0800 12) 00000000 (Not Committed Yet 2013-06-02 18:25:21 +0800 13) 00000000 (Not Committed Yet 2013-06-02 18:25:21 +0800 14) this is the change of work directory.
我们还可以使用--show-stats参数来显示其他的统计数据，如下：
$git blame --show-stats aa ^2cae297 (xin 2013-06-02 17:56:14 +0800 1) The beginning is to learn git blame ^2cae297 (xin 2013-06-02 17:56:14 +0800 2) the second to add some difference. ^2cae297 (xin 2013-06-02 17:56:14 +0800 3) ok, let's go ,you can do it ! aba91773 (xin 2013-06-02 17:58:26 +0800 4) aba91773 (xin 2013-06-02 17:58:26 +0800 5) aba91773 (xin 2013-06-02 17:58:26 +0800 6) aba91773 (xin 2013-06-02 17:58:26 +0800 7) After first commit ,I want to add some charater to test git blame 9db59f5a (xin 2013-06-02 18:09:21 +0800 8) 9db59f5a (xin 2013-06-02 18:09:21 +0800 9) 9db59f5a (xin 2013-06-02 18:09:21 +0800 10) 9db59f5a (xin 2013-06-02 18:09:21 +0800 11) This is the third commit ,for testing -b option 00000000 (Not Committed Yet 2013-06-02 18:25:21 +0800 12) 00000000 (Not Committed Yet 2013-06-02 18:25:21 +0800 13) 00000000 (Not Committed Yet 2013-06-02 18:25:21 +0800 14) this is the change of work directory. num read blob: 6 num get patch: 3 num commits: 3
我们还可以使用-f或者--show-name来显示文件的原始文件名，还可以使用-n或者--show-number来显示文件的行数，如下截图：
$git blame --show-stats aa ^2cae297 (xin 2013-06-02 17:56:14 +0800 1) The beginning is to learn git blame ^2cae297 (xin 2013-06-02 17:56:14 +0800 2) the second to add some difference. ^2cae297 (xin 2013-06-02 17:56:14 +0800 3) ok, let's go ,you can do it ! aba91773 (xin 2013-06-02 17:58:26 +0800 4) aba91773 (xin 2013-06-02 17:58:26 +0800 5) aba91773 (xin 2013-06-02 17:58:26 +0800 6) aba91773 (xin 2013-06-02 17:58:26 +0800 7) After first commit ,I want to add some charater to test git blame 9db59f5a (xin 2013-06-02 18:09:21 +0800 8) 9db59f5a (xin 2013-06-02 18:09:21 +0800 9) 9db59f5a (xin 2013-06-02 18:09:21 +0800 10) 9db59f5a (xin 2013-06-02 18:09:21 +0800 11) This is the third commit ,for testing -b option 00000000 (Not Committed Yet 2013-06-02 18:25:21 +0800 12) 00000000 (Not Committed Yet 2013-06-02 18:25:21 +0800 13) 00000000 (Not Committed Yet 2013-06-02 18:25:21 +0800 14) this is the change of work directory. num read blob: 6 num get patch: 3 num commits: 3
我们还可以使用-p或者--porcelain让输出以更精美的形式出现，截图如下：
$git blame -p aa

下面是其中常用的参数：
(1)-t参数可以让时间以时间戳的形式显示。
(2)-l参数可以让其显示长传的哈希码，而不是哈希码的前几个字符。
(3)-s参数可以简化输出，不显示作者以及时间戳。
(4)-e参数输出user.email替换user.name。
(5)-w参数可以忽略空行的不同。
(6)-L n，m参数可以查看指定的n行到m行的修改内容。
