Python日誌監控（發音版）

前段時間有朋友讓幫忙做一個日誌監控的指令碼，要求如下：

• 1.windows環境
• 2.當匹配日誌關鍵字時會發出聲音，匹配的關鍵字不同，播放的聲音不同
• 3.能做到即時響應

於是從網上找了個windows版的tail，使用python簡單寫了個小指令碼，代碼如下：

#!/usr/bin/env python
# encoding: utf-8

"""
MonitorLog.py

Usage: MonitorLog.py ...
Monitor the log file

-f  log file
-h  help info

python MonitorLog.py -f C:\monitor.log

其中moniter_keyword.txt格式為keyword:sound.wav 樣本檔案如下：
