==Adding a timestamp to ping's output==
Here's a command to save a record of ten thousand pings with a timestamp. This code, to be run in a BASH terminal command line, combines the methods, found in the references below, of adding a timestamp and saving the output to a file:
 ping -i 2 -c 10000 google.com | while read pong; do echo "$(date -j '+%Y-%m-%d %H:%M:%S') $pong" 1>>~/PingsWithDate.txt;done
;Explanation of commands in the above code:
 ping google.com
:Send a periodic message to google.com asking for a simple reply. The result is the number of each ping in series (icmp_seq), the maximum amount of IP routers allowed to transmit the message, and the time taken by the round-trip.
 -i 2
:Wait 2 seconds between pings.
 -c 10000
:Repeat the ping ten thousand times.
 |
:"Pipe" the output to the following command.
 while read pong; do
:If there is any output from the pipe, set the variable pong to the output and do the following commands up to "done", returning here to check for more output. Go to the command after "done" if there is no more output.
 echo ""
:Copy the following to the standard output.
 $(date -j '+%Y-%m-%d %H:%M:%S')
:Print the current date, without trying to set it (-j), in the format of year-month-date hour:minute:second.
 $pong
:Also print the output from the ping command stored in the variable pong.
 1>>~/PingsWithDate.txt
:Redirect the output of echo from standard output to the end of the file PingsWithDate.txt in the user folder. If the file doesn't yet exist, a new file will be made, else the results will be appended to the file without overwriting the existing contents.
