Linux下长时间ping网络加时间戳并记录到文本

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@ www.linuxidc.com ~]# ping 192.168.2.1 -c 10
PING 192.168.2.1 (192.168.2.1) 56(84) bytes of data.
64 bytes from 192.168.2.1: icmp_seq=1 ttl=64 time=0.638 ms
64 bytes from 192.168.2.1: icmp_seq=2 ttl=64 time=0.341 ms

64 bytes from 192.168.2.1: icmp_seq=6 ttl=64 time=0.339 ms
64 bytes from 192.168.2.1: icmp_seq=7 ttl=64 time=0.243 ms
64 bytes from 192.168.2.1: icmp_seq=8 ttl=64 time=0.234 ms
64 bytes from 192.168.2.1: icmp_seq=9 ttl=64 time=0.333 ms
64 bytes from 192.168.2.1: icmp_seq=10 ttl=64 time=0.284 ms

--- 192.168.2.1 ping statistics ---
10 packets transmitted, 10 received, 0% packet loss, time 9002ms
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@ www.linuxidc.com ~]# 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

rtt min/avg/max/mdev = 0.265/0.331/0.436/0.052 ms    10:30:30
然后我们把信息输出到文本:

最后,我们需要把任务放到后台去:
