Java调用shell脚本并获得结果

/**

     * @param shell 需要运行的shell脚本
     */
    public static void execShell(String shell){
        try {
            Runtime rt = Runtime.getRuntime();
            rt.exec(shell);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }


/**

     *
     * @param shStr
     *            需要执行的shell
     * @return

     */
    public static List runShell(String shStr) throws Exception {
        List 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);
        }

        return strList;
    }

注:如果sh中含有awk,一定要按new String[]{"/bin/sh","-c",shStr}写,才可以获得流
