When I ping I have this display:

> ping -i 4 www.google.fr 

64 bytes from wi-in-f94.1e100.net (173.194.67.94): icmp_seq=503 ttl=46 time=45.5 ms

64 bytes from wi-in-f94.1e100.net (173.194.67.94): icmp_seq=509 ttl=46 time=45.1 ms

I'd like to have the time of the ping before.

Something like:

> (right functions) + ping -i 7 www.google.fr

How would you do this in a command line (if it's possible)?

Use:

ping www.google.fr | while read pong; do echo "$(date): $pong"; done

You will get the result like this:

Another possibility to use the ping -D option which gets you the timestamp as Unix time.

Here a version of "Achu" command with slightly different format:

ping www.google.com -i 10 -c 3000 | while read pong; do echo "$(date +%Y-%m-%d_%H%M%S): $pong"; done >PingTest_2014-01-04.log

That gets you:

You can also use gawk (or awk, if your /etc/alternatives/awk points to /usr/bin/gawk):

ping -c 4 www.google.fr | gawk '{print strftime("%c: ") $0}'

This is similar to the approach in Achu's answer, but ping's output is piped to gawk instead of a shell loop that calls date. As with that approach, it works without -c, but if you don't pass -c n to make ping stop after n pings, and you stop the loop with Ctrl+C, ping won't print the usual statistics.

ek@Io:~$ ping -c 4 www.google.fr | gawk '{print strftime("%c: ") $0}'

This happens whether ping's output is piped to gawk or a shell while loop. The reason is that command on the right side of the pipe, rather than ping, receives SIGINT when Ctrl+C is pressed, and ping does not know to print the statistics before being terminated.

If you have run ping without -c on the left side of a pipe (as shown above) and you want to terminate it in such a way that it still prints the statistics, then instead of pressing Ctrl+C in the terminal where it is running, you could run kill -INT PID from another terminal, replacing PID with the process ID of the ping command. If you're only running one instance of ping then you could simply use killall -INT ping.

Alternatively, you could replace the ping command on the left side of the pipe with a command that runs a shell, reports the process ID of that shell, and then replaces that shell with the ping command (causing it to have the same PID):

sh -c 'echo $$; exec ping www.google.fr' | gawk '{print strftime("%c: ") $0}'

Then the first line of output, will show the process ID of the ping command (which will typically be different each time). It would look like this, but with a different time and date and probably a different process ID:

Tue 20 Mar 2018 12:11:13 PM EDT: 7557

Then, from another terminal, you can run kill -INT 7557, replacing 7557 with the actual process ID you saw, to terminate the ping command in such a way as to cause it to print statistics.

(If you take advantage of your shell's job control features, then you can achieve this within the same terminal, too. But if you want to copy text from your terminal without having to remove any extranous part where you ran commands in that terminal, then you should terminate ping from a separate terminal.)

There is a utility called 'ts', which reads stdin, adds timestamps, and writes it to stdout:

ping google.in | xargs -n1 -i bash -c 'echo `date +"%Y-%m-%d %H:%M:%S"`" {}"'

If your interested in saving it in file, then type the below command in the terminal

ping google.in | xargs -n1 -i bash -c 'echo `date +"%Y-%m-%d %H:%M:%S"`" {}"' >> "/home/name_of_your_computer/Desktop/Ping_Test.txt"

You don't need to create any text files, it'll automatically do

(thanks to Achu and Eliah Kagan for the ideas)
there's a way to

• add time to ping output


• keep footnotes of ping
  


• and terminate this whole construction with ctrl+c
  

to do this one should instruct right part of the command (after the pipe) to ignore SIGINT using trap "" INT:

$ ping www.google.fr | bash -c 'trap "" INT; awk "{print strftime("%c - ") $0}"'
