-r|--recursive   Watch directories recursively. #递归查询目录
-q|--quiet      Print less (only print events). #打印监控事件的信息

--excludei <pattern>  Like --exclude but case insensitive.    #排除文件或目录时，不区分大小写。
--timefmt <fmt> strftime-compatible format string for use with %T in --format string. #指定时间输出的格式
--format <fmt>  Print using a specified printf-like format string; read the man page for more details.
#打印使用指定的输出类似格式字符串
-e|--event <event1> [ -e|--event <event2> ... ] Listen for specific event(s).  If omitted, all events are  listened for.   #通过此参数可以指定需要监控的事件，如下所示:
