git diff命令详解
git diff命令详解
diff里面a表示前面那个变量,b表示第二个变量
HEAD commit版本
Index staged版本
a、查看尚未暂存的文件更新了哪些部分,不加参数直接输入
git diff
此命令比较的是工作目录(Working tree)和暂存区域快照(index)之间的差异
也就是修改之后还没有暂存起来的变化内容。
b、查看已经暂存起来的文件(staged)和上次提交时的快照之间(HEAD)的差异
git diff --cached
git diff --staged
显示的是下一次commit时会提交到HEAD的内容(不带-a情况下)
c、显示工作版本(Working tree)和HEAD的差别
git diff HEAD
d、直接将两个分支上最新的提交做diff
git diff topic master 或 git diff topic..master
e、输出自topic和master分别开发以来,master分支上的changed。
git diff topic...master
Changes that occurred on the master branch since when the topic
branch was started off it
f、查看简单的diff结果,可以加上--stat参数
git diff --stat
g、查看当前目录和另外一个分支的差别
git diff test
显示当前目录和另一个叫'test'分支的差别
git diff HEAD -- ./lib
显示当前目录下的lib目录和上次提交之间的差别(更准确的说是在当前分支下)
h、比较上次提交commit和上上次提交
git diff HEAD^ HEAD
i、比较两个历史版本之间的差异
git diff SHA1 SHA2
