How can I add a newline after match is found

Question

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

Answer 1

In a substitution, & in the replacement will be replaced with whatever matched. So:

sed 's/64/\n&/g' file

Answer 2

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
