Java代码操作Windows命令与Linux命令

1. 操作Windows：

      /*
       *1.txt 从work目录移动到in目录
       * */
       public static void  mvIn(){
           String[] command =
                   {
                           "cmd",
                   };
           Process p = null;
           try {
               p = Runtime.getRuntime().exec(command);
               new Thread(new SyncPipe(p.getErrorStream(), System.err)).start();
               new Thread(new SyncPipe(p.getInputStream(), System.out)).start();
               PrintWriter stdin2 = new PrintWriter(p.getOutputStream());
               stdin2.println("move E:\\work\\"+fileName+"\tE:\\in");//将work下的文件时间最小的文件转移到
               stdin2.close();//执行命令
           }catch (Exception e) {
               System.out.println(e.getMessage()+"有异常");
           }
       }
   

//新建一个接口 （上下为两个类）

class SyncPipe implements Runnable{
    public SyncPipe(InputStream istrm, OutputStream ostrm) {
        istrm_ = istrm;
        ostrm_ = ostrm;
    }
    public void run() {
        try{
            final byte[] buffer = new byte[1024];
            for (int length = 0; (length = istrm_.read(buffer)) != -1;){
                ostrm_.write(buffer, 0, length);
            }
        }
        catch (Exception e) {
            throw new RuntimeException("处理命令出现错误："+e.getMessage());
        }
    }
    private final OutputStream ostrm_;
    private final InputStream istrm_;
}

2.操作Linux：

RemoteExecuteCommand rec = new RemoteExecuteCommand("IP地址", "用户名", "密码");
//查询/usr/HDWork/in 目录下的  时间最小的文件名
String fileName = rec.execute("cd /usr/HDWork/in ; ls -lrt|sed -n \"2, 1p\"|awk '{print $9}'");

注*两条Linux命令同时执行 用 “ ； ”分割
