批次檔工具（java+shell命令實現）

有一堆語料需要處理一下才能使用，本來應該可以直接用shell指令碼直接處理的。但是對shell指令碼不熟，只會簡單的一些命令。因此就利用java+shell命令實現。
也許，直接用shell指令碼處理是最好的。或許你有什麼絕妙的方法也請告訴我哦！當然，我這個工具有個好處，就是如果通過shell命令實現不了的功能，可以用java實現，添加相應介面就可以了。
工具裡面的功能，Java負責調度，shell負責具體功能。意思是說，我寫的shell命令是針對單個檔案操作的，java通過迴圈來調用那些shell命令，以此實現批處理。目前根據需要寫了一些功能，比如字串替換，文本頭部或末尾新增內容，文本轉碼。代碼設計上，我留了一個叫Operation的介面，很容易添加新的文本操作功能。
