git學習-使用git log查看某個文件的歷史

（1）方法一
git log --pretty=oneline 文件名

例如：想搜索剛纔的frameworks/base/packages/SystemUI/AndroidManifest.xml文件的提交記錄，就可以使用命令：

 

oyp@buildServer3:~/E580$ git log --pretty=oneline frameworks/base/packages/SystemUI/AndroidManifest.xml
34b7ac981a39193ca78e0d4673ce66515c23988d     [add a new feature to show the battery voltage value and level]     1.Support show the level of 
c1d6879f098775f1d703dfcfe814c4d726be47ad [Create MT6753-6M AP source repository]

 

如上所示，打印出來的就是針對文件frameworks/base/packages/SystemUI/AndroidManifest.xml文件的所有的改動歷史，每一行最前面的那一長串數字就是每次提交形成的哈希值，接下來使用git show即可顯示具體的某次的改動的修改。

 

下面就可以使用git show 命令查看具體的修改詳情了。如：

git show <git提交版本號> <文件名>

 

 git show 34b7ac981a39193ca78e0d4673ce66515c23988d frameworks/base/packages/SystemUI/AndroidManifest.xml

這樣指定版本號，指定文件的就可以直接查看該文件的修改詳情，不要看該版本號其他文件的修改。如下所示：

 

 

oyp@buildServer3:~/E580$ git show 34b7ac981a39193ca78e0d4673ce66515c23988d frameworks/base/packages/SystemUI/AndroidManifest.xml

（2）方法二

很多時候，你只對某個特定文件的更改感興趣。爲了顯示某個特定文件的歷史，你只需要傳入文件路徑。比如說，下面這個命令返回所有和foo.py和bar.py文件相關的提交：
git log -- foo.py bar.py
需要注意，文件名的大小寫。
