由于一些原因，比如需要检查网络之间是否存在掉包等问题，会长时间去ping一个地址，由于会输出大量的信息而且最好要有时间戳，因此我们可以使用简单的几个shell命令组合就可以实现：长时间ping一个地址，记录每次ping的时间戳，并输出到文本保存，另外我们还可以将这个动作放到后台去执行，以免登陆注销之后被中断。

首先是长时间ping，这个非常简单，使用参数-c即可：

[root@test ~]# ping 192.168.2.1 -c 10

--- 192.168.2.1 ping statistics ---

rtt min/avg/max/mdev = 0.234/0.330/0.638/0.109 ms

上面我们ping了10次，每次的时间1秒，因此比如你要ping连天那么就是60*60*24*2=172800。

接下来是加时间戳：

root@test ~]# ping 192.168.2.1 -c 10 | awk '{ print $0"\t" strftime("%H:%M:%S",systime()) } '

然后我们把信息输出到文本：

[root@test ~]# cat ping.log
