git-diff - git diff 查看两个分支的区别，如何将结果输出到指定文件

Question

git diff [branchA] [branchB]

用以上这个命令可输出两个分支的区别，但是不同的文件太多，在命令行查看不是很方便，想输出到文件中查看，不知道如何加参数？

===================================
补充：找到答案：

// >> 后加输出文件的路径、文件名和后缀名
 git diff [branchA] [branchB] >>d:/diff/exportname.diff

Answer 1

linux的重定向命令
覆盖 git diff [branchA] [branchB] > a.txt
追加 git diff [branchA] [branchB] >> a.txt

Answer 2

git diff --color > foo.diff

foo.diff用notepad++/sublime 之类的编辑器打开，高亮颜色
