For some reasons, such as the need to check whether there is a switch between the network and other issues, a long time to ping an address, because it will output a lot of information and it is best to have a timestamp, so we can use a simple combination of several shell commands can be achieved: a long time ping an address, Record the time stamp of each ping, and output to the text save, in addition, we can put this action in the background to execute, so as not to log off after being interrupted.
The first is a long time ping, this is very simple, using the parameter-C can be:
[Root@test ~]# Ping 192.168.2.1-c 10

RTT Min/avg/max/mdev = 0.234/0.330/0.638/0.109 ms
We ping the above 10 times, each time 1 seconds, so for example you want to ping the sky is 60*60*24*2=172800.
The next step is to add time stamps:
Root@test ~]# Ping 192.168.2.1-c 10 | awk ' {print $ ' \ t ' strftime ("%h:%m:%s", Systime ())} '
PING 192.168.2.1 (192.168.2.1) bytes of data. 10:30:21

Then we output the information to the text:
[Root@test ~]# ping 192.168.2.1-c 10 | awk ' {print $ ' \ t ' strftime ("%h:%m:%s", Systime ())} ' >ping.log

Finally, we need to put the task backstage:
