dos保存adb logcat读取的Android信息

/*****************************************************************************
 *                      dos保存adb logcat读取的Android信息
 * 声明：
 *     由于dos下用logcat直接看Android系统信息不方便，眼花缭乱，眼神真心不好使，
 * 于是觉得dos下面应该有办法能够将logcat信息保存下来，于是找到这个重定向的方式。

一、参考文档：
    cmd连接android手机,并使用logcat输出的log信息
        http://jingyan.baidu.com/article/86112f135add5627379787ee.html

二、adb logcat -h
    Usage: logcat [options] [filterspecs]
    options include:
      -s              Set default filter to silent.
                      Like specifying filterspec '*:s'
      -f <filename>   Log to file. Default to stdout
      -r [<kbytes>]   Rotate log every kbytes. ( if unspecified). Requires -f
      -n <count>      Sets max number of rotated logs to <count>, default
      -v <format>     Sets the log print format, where <format> is one of:

                      brief process tag thread raw time threadtime long

      -c              clear (flush) the entire log and exit
      -d              dump the log and then exit (don't block)
      -t <count>      print only the most recent <count> lines (implies -d)
      -g              get the size of the log's ring buffer and exit
      -b <buffer>     Request alternate ring buffer, 'main', 'system', 'radio'
                      or 'events'. Multiple -b parameters are allowed and the
                      results are interleaved. The default is -b main -b system.
      -B              output the log in binary

三、解决方法：
    adb logcat -v time -b radio > ublox.txt

四、ublox.txt部分内容：
