这篇文章主要介绍了java执行Linux命令的方法,涉及对Java中Runtime.exec()函数的应用,具有一定的参考借鉴价值,需要的朋友可以参考下

本文实例讲述了java执行Linux命令的方法。分享给大家供大家参考。具体实现方法如下：

public class StreamGobbler extends Thread {

    InputStream is;
    String type;

    public StreamGobbler(InputStream is, String type) {
        this.is = is;
        this.type = type;
    }

    public void run() {
        try {
            InputStreamReader isr = new InputStreamReader(is);
            BufferedReader br = new BufferedReader(isr);
            String line = null;
            while ((line = br.readLine()) != null) {
                if (type.equals("Error")) {
                    System.out.println("Error   :" + line);
                } else {
                    System.out.println("Debug:" + line);
                }
            }
        } catch (IOException ioe) {
            ioe.printStackTrace();
        }
    }
}
private void shell(String cmd)
{
        String[] cmds = { "/bin/sh", "-c", cmd };
        Process process;

        try
        {
            process = Runtime.getRuntime().exec(cmds);

            StreamGobbler errorGobbler = new StreamGobbler(process.getErrorStream(), "Error");
            StreamGobbler outputGobbler = new StreamGobbler(process.getInputStream(), "Output");
            errorGobbler.start();
            outputGobbler.start();
            try
            {
                process.waitFor();
            }
            catch (InterruptedException e)
            {
                e.printStackTrace();
            }
        }
        catch (IOException e)
        {
            e.printStackTrace();
        }
}
