How can I modify real time verbose output of a command in bash?

Question

If I run command ping google.com. It will give continuous output on the terminal. Example output:

64 bytes from 74.125.130.101: icmp_seq=1 ttl=42 time=980 ms
64 bytes from 74.125.130.101: icmp_seq=2 ttl=42 time=1883 ms
64 bytes from 74.125.130.101: icmp_seq=3 ttl=42 time=1947 ms
64 bytes from 74.125.130.101: icmp_seq=4 ttl=42 time=1273 ms
64 bytes from 74.125.130.101: icmp_seq=5 ttl=42 time=848 ms
64 bytes from 74.125.130.101: icmp_seq=6 ttl=42 time=1072 ms
64 bytes from 74.125.130.101: icmp_seq=7 ttl=42 time=1202 ms

Now if I want to modify each output line to show only the 64 bytes from 74.125.130.101: part, how can I do that?

I want to know a generic method which will work with other commands too which produce real time verbose output.

Answer 1

awk-way:

ping google.com | awk -F ":" '{print $1}'

if you need trailing colons exactly like in the question:

ping google.com | awk -F ":" '{print $1 ":"}'

grep-way:

ping google.com | grep -o "^.*:"

sed-way:

ping google.com | sed  's/\(.*:\).*/\1/'

Answer 2

Use cut through a pipe:

ping google.com | cut -d":" -f1
