I want to add a newline after number 64, using awk or sed, in ping output such as this:
64 bytes from 170.198.42.128: icmp_seq=1 ttl=60 time=83.4 ms 64 bytes from
170.198.42.128: icmp_seq=2 ttl=60 time=76.6 ms 64 bytes from 170.198.42.128: icmp_seq=3
ttl=60 time=70.8 ms 64 bytes from 170.198.42.128: icmp_seq=4 ttl=60 time=76.6 ms ---
170.198.42.128 ping statistics --- 4 packets transmitted, 4 received, 0% packet loss, time
3000ms rtt min/avg/max/mdev = 70.861/76.924/83.493/4.473 ms
I've tried
cat file | sed 's/64/\n/g'
but this replaces the number 64. I want to break the pattern and display the ping command pattern starting with 64 properly.
I tried using append and insert mode ..but not using them correctly

In the first line, we added the line number for insertion. Secondly, we specified the insert action in the same line. Then, in the next line, we added the phrase we wanted to insert. In the end, we need to put a dot (.) to end the input mode and then add xit to save the changes and quit the editor.
There are different ways to insert a new line in a file using sed, such as using the “a” command, the “i” command, or the substitution command, “s“.
Sometimes we need to work with a file for programming purposes, and the new line requires to add at the end of the file. This appending task can be done by using 'echo' and 'tee' commands. Using '>>' with 'echo' command appends a line to a file.
In a substitution, & in the replacement will be replaced with whatever matched. So:
sed 's/64/\n&/g' file
This sed command should work with both gnu and BSD sed versions:
sed $'s/64/\\\n&/g' file
64 bytes from 170.198.42.128: icmp_seq=1 ttl=60 time=83.4 ms
64 bytes from
170.198.42.128: icmp_seq=2 ttl=60 time=76.6 ms
64 bytes from 170.198.42.128: icmp_seq=3
ttl=60 time=70.8 ms
64 bytes from 170.198.42.128: icmp_seq=4 ttl=60 time=76.6 ms ---
170.198.42.128 ping statistics --- 4 packets transmitted, 4 received, 0% packet loss, time
3000ms rtt min/avg/max/mdev = 70.861/76.924/83.493/4.473 ms
Update: Here is gnu awk command to do the same:
awk '1' RS='64' ORS='\n64' file
