批处理文件工具（java+shell命令实现）

批处理文件工具（java+shell命令实现）

有一堆语料需要处理一下才能使用，本来应该可以直接用shell脚本直接处理的。
但是对shell脚本不熟，只会简单的一些命令。
因此就利用java+shell命令实现。

也许，直接用shell脚本处理是最好的。或许你有什么绝妙的方法也请告诉我哦！
当然，我这个工具有个好处，就是如果通过shell命令实现不了的功能，可以用java实现，
添加相应接口就可以了。

工具里面的功能，Java负责调度，shell负责具体功能。
意思是说，我写的shell命令是针对单个文件操作的，java通过循环来调用那些shell命令，以此实现批处理。
目前根据需要写了一些功能，比如字符串替换，文本头部或末尾添加内容，文本转码。
代码设计上，我留了一个叫Operation的接口，很容易添加新的文本操作功能。

以下是源代码：

package com.linger.fileoperation;

public interface Operation
{
public void Run(String file,String[] options);
}

package com.linger.fileoperation;

import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.io.LineNumberReader;

public class Cmd {

/**
* java调用shell命令的封装
* 返回命令执行后的输出	//refer http://www.linuxidc.com/Linux/2012-04/58416.htm */
public static String Run(String[] cmd, int tp) {
StringBuffer buf = new StringBuffer(1000);
String rt = "-1";
try {
Process pos = Runtime.getRuntime().exec(cmd);
pos.waitFor();
if (tp == 1) {
if (pos.exitValue() == 0) {
rt = "执行完毕！";
}
} else {
InputStreamReader ir = new InputStreamReader(
pos.getInputStream());
LineNumberReader input = new LineNumberReader(ir);
String ln = "";
while ((ln = input.readLine()) != null) {
buf.append(ln + "\n");
}
rt = buf.toString();
input.close();
ir.close();
}
} catch (java.io.IOException e) {
rt = e.toString();
} catch (Exception e) {
rt = e.toString();
}
return rt;
}
