批处理文件的工具（java+shell为了实现）

批处理文件的工具（java+shell为了实现）

有一堆语料须要处理一下才干使用，本来应该能够直接用shell脚本直接处理的。

可是对shell脚本不熟，仅仅会简单的一些命令。

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。

也许你有什么绝妙的方法也请告诉我哦！

当然。我这个工具有个优点，就是假设通过shell命令实现不了的功能，能够用java实现，

加入对应接口就能够了。

工具里面的功能。Java负责调度，shell负责详细功能。

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。

眼下依据须要写了一些功能，比方字符串替换，文本头部或末尾加入内容。文本转码。

代码设计上。我留了一个叫Operation的接口，非常easy加入新的文本操作功能。

下面是源码：

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
	 * 返回命令运行后的输出	//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 = "运行完成。";
				}
			} 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;
	}

	public static void main(String[] args)
	{
		// TODO Auto-generated method stub
