如果你要查看文件的每个部分是谁修改的, 那么  git blame  就是不二选择. 只要运行' git blame  \[filename\] ', 你就会得到整个文件的每一行的详细修改信息:包括SHA串,日期和作者:

译者注: Git采用SHA1做为hash签名算法, 在本书中,作者为了表达方便,常常使用SHA来代指SHA1. 如果没有特别说明, 本书中的SHA就是SHA1的代称.

$  git   blame   sha1\_file.c

...

你也可以用"-L"参数在命令(blame)中指定开始和结束行:

$> git   blame   -L   160 , +10   sha1\_file.c
