diff和patch的使用示例

diff a.txt b.txt > some.patch
patch a.txt some.patch
#pathc之后将会使两者(a.txt和b.txt)一致

diff两个文件，结果显示46a47,48，可理解为：
1）46：第一个文件（或旧文件）的行号，表示差异开始的位置。
2）a：操作类型，这里是 “add”（添加），表示需要在第一个文件的第46行后添加内容。
3）47,48：第二个文件（或新文件）的行号范围，表示需要添加的内容来自新文件的第47到48行。
总体意思是：你需要将第二个文件的第47-48行内容，添加到第一个文件的第46行之后，才能使两者一致。

a:add, d:delete, c: change
