java調linux的shell命令

功能需要所以要在jsp的後臺 用Java代碼調用.sh文件

public boolean runShell(String command,String date) throws IOException{
		String command2 = command + " " + date;
		Process process=Runtime.getRuntime().exec(command2);
		System.out.println("開始執行shell=="+command2);
		BufferedReader br = new BufferedReader(new InputStreamReader(process
				.getInputStream()));
		String line = new String();
		while ((line = br.readLine()) != null) {
			System.out.println(line);
		}
		try {
			process.waitFor();
		} catch (InterruptedException e) {
			e.printStackTrace();
			System.err.println("processes was interrupted");
			return false;
		}
		br.close();
		int ret = process.exitValue();
		System.out.println(ret);
		System.out.println("執行完畢!");
		return true;
	}

   command爲.sh文件所在的絕對路徑,date是給命令傳的時間參數.如果web部署的tomcat和shell文件所在的不是同一個用戶下,就需要在shell文件裏面 先切換用戶

   su - xxx -c  " /home/xxx/test"
