java调用linux脚本 shell

　　最近项目需要用java调用shell，在网找找了些文章，总结如下：

import java.io.IOException;
import java.io.InputStreamReader;
import java.io.LineNumberReader;
import java.util.ArrayList;
import java.util.List;

public class Shell {
    
    public static void main(String[] args) {
        try {
            runShell("/root/shell/test.sh arg1 arg2 arg3");
        } catch (Exception e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }
    
    
    /**
     * 调用shell，
     * parameter:arg1  arg2 arg3,
     * return  void
     * */
    public void callShell(){
        try {
            Runtime rt = Runtime.getRuntime();  
            rt.exec("/root/shell/test.sh arg1 arg2 arg3");
        } catch (IOException e) {
            e.printStackTrace();
        }  
    }
    
    /** 
     * 运行shell 
     *  
     * @param shStr  需要执行的shell绝对路径 和参数 
     * @return echo 打印结果保存在list中,shell中echo值放到list中
     * @throws IOException 
     */  
    public static List runShell(String shStr) throws Exception {  
        List<String> strList = new ArrayList();  
  
        Process process;  
        process = Runtime.getRuntime().exec(new String[]{"/bin/sh","-c",shStr},null,null);  
        InputStreamReader ir = new InputStreamReader(process  
                .getInputStream());  
        LineNumberReader input = new LineNumberReader(ir);  
        String line;  
        process.waitFor();  
        while ((line = input.readLine()) != null){  
            strList.add(line);  
            System.out.println(line);
        }  
        return strList;  
    }  

}
