Linux下长时间ping网络加时间戳并记录到文本

root@test ~]# ping 192.168.2.1 -c 10 | awk '{ print $0"\t" strftime("%H:%M:%S",systime()) } '
PING 192.168.2.1 (192.168.2.1) 56(84) bytes of data.    10:30:21

然后我们把信息输出到文本：
[root@test ~]# ping 192.168.2.1 -c 10 | awk '{ print $0"\t" strftime("%H:%M:%S",systime()) } '>ping.log
[root@test ~]# cat ping.log

最后，我们需要把任务放到后台去：
[root@test ~]# nohup ping 192.168.2.1 -c 10 | awk '{ print $0"\t" strftime("%H:%M:%S",systime()) } '>ping1.log &

注：nohup ping 192.168.2.1 -c 10 | awk '{ print $0"\t" strftime("%Y-%m-%d %H:%M:%S",systime()) } '>ping1.log 2>&1 &

这样每隔4K左右会打印到文件
