java执行windows、shell命令

Java中调用windows命令，可以一次性执行多个命令。稍微改一下，也可以执行Linux l命令或shell脚本。

public class RuntimeTask {public static void main(String[] args) {Process process;//一次性执行多个命令String cmd = "cmd /c \"E: && dir && cd gitBackup && dir && pullAll.bat\"";try {Runtime runtime = Runtime.getRuntime();System.out.println("开始执行。。。");process = runtime.exec(cmd);//打印执行的输出结果InputStream is = process.getInputStream();InputStreamReader isr = new InputStreamReader(is, "gbk"); //gbk：解决输出乱码BufferedReader br = new BufferedReader(isr);String line;while ((line = br.readLine()) != null){System.out.println(line);}is.close();isr.close();br.close();}catch (IOException e){e.printStackTrace();}}}
