命令是logcat，参数参照下面的：

static void show_help(const char *cmd)
{
    fprintf(stderr,"Usage: %s [options] [filterspecs]/n", cmd);

    fprintf(stderr, "options include:/n"
                    "  -s              Set default filter to silent./n"
                    "                  Like specifying filterspec '*:s'/n"
                    "  -f <filename>   Log to file. Default to stdout/n"
                    "  -r [<kbytes>]   Rotate log every kbytes. (16 if unspecified). Requires -f/n"
                    "  -n <count>      Sets max number of rotated logs to <count>, default 4/n"
                    "  -v <format>     Sets the log print format, where <format> is one of:/n/n"
                    "                  brief process tag thread raw time threadtime long/n/n"
                    "  -c              clear (flush) the entire log and exit/n"
