關於patch...

對於這些基本tool不熟實在是很不方便啊～～

------------

vi t1 t2
t1:
My Name is barry.
I am 20 years old.
Your name is tina.
How old are you?

t2:
My name is marry.
I am 20 years old.
You name is tom.
How old are you?

//產生diff檔，t1視為較舊的檔案，需要被更新
diff -Naur ./t1 ./t2 > t_patch

//patch t1
patch -p0 < t_patch

patch的參數-p0，-p1，-p2表示對於要處理的file/folder的階層。
