比對兩個資料夾下的檔並輸出彩色 diff

平常都在 git repo 內做 diff，一時之間不知道要怎麼比對兩個資料夾底下的檔案

這邊作一下紀錄…

λ ~/temp/ diff -bur FOLDER_1 FOLDER_2

會發現輸出的 diff 居然沒有顏色…

於是乎又找到 colofdiff

直接 apt-get install colordiff 即可，就會變成這樣

diff -bur FOLDER_1 FOLDER_2 | colordiff

// 存起來
diff -bur FOLDER_1 FOLDER_2 | colordiff > your.diff

打完收工。
