[轉]git使用點滴：如何查看commit的內容

在push以前有時候會不放心是否是忘記加某些文件，或者是否是多刪了個什麼東西，這時候但願可以看看上次commit都作了些什麼。

一開始想到的是用git diff，可是git diff用於當前修改還沒有commit的時候較爲方便，一旦commit後，須要指定上次節點的名稱（一個hash值），不方便。這種時候用git log更合適，由於commit的內容會以log來記錄。

下面記錄幾個經常使用的情境以及對應的命令。

 

僅僅想看最近誰有提交，以及提交的描述

有了這幾條命令，基本上對於想看最近更改的情境就能夠應付過去了。最後一條並不很經常使用，若是有visual的工具可能更直觀些。
