根据时间段查询log日志，拆分日志等

示例一：
日志格式：
wechat_Log:[2014-09-17 09:09:22]  WARN JSONObject:446 - Tried to assign property
wechat_Log:[2014-09-17 09:09:22]  WARN JSONObject:446 - Tried to assign property
wechat_Log:[2014-09-17 09:09:22]  WARN JSONObject:446 - Tried to assign property
wechat_Log:[2014-09-17 09:09:22]  WARN JSONObject:446 - Tried to assign property
wechat_Log:[2014-09-17 09:09:22]  WARN JSONObject:446 - Tried to assign property
wechat_Log:[2014-09-17 09:09:22]  WARN JSONObject:446 - Tried to assign property


使用命令：
cat info.log.2014-09-17 | grep -E '2014-09-17 09:09:[23-59]' | more

使用命令：
gawk -F: '{ printf ("%s:%s:%s\n", $2,$3,$4) }' web-20141216.log | grep -E '00:01:5[5:9]' | more

解释：先将日志按照冒号拆分，然后取时间部分以及后续字符部分，并查找00:01:5X时间的日志。
