dmesg时间转换

对dmesg的时间戳，做了一个转化工具：ts_dmesg.sh

借助awk 和shell实现：

#!/bin/sh

uptime_ts=`cat /proc/uptime | awk '{ print $1}'`

#echo $uptime_ts

dmesg | awk -v uptime_ts=$uptime_ts 'BEGIN {

    now_ts = systime();

    start_ts = now_ts - uptime_ts;

    #print "system start time seconds:", start_ts;

    #print "system start time:", strftime("[%Y/%m/%d %H:%M:%S]", start_ts);

}

{

    print strftime("[%Y/%m/%d %H:%M:%S]", start_ts + substr($1, 2, length($1) - 2)), $0

}'
