How to ping IPs and get only ip and ttl in the output?

Question

linux

I have a hosts.txt file, it contains a list of network ip addresses. I need to ping each of these IPs and get something like "192.168.X.X => ttl=64" in the output. How can this be implemented?

Answer 1

#!/bin/bash
FILE=$1
while read LINE; do
ttlstr=$(ping -c1 -w1 $LINE | grep -o 'ttl=[0-9][0-9]*') || {
printf "%s is Offline\n" "$LINE"
continue;
}
ttl="${ttlstr#*=}"
printf "%s is Online, ttl=%d\n" "$LINE" "$ttl"
done < $FILE
file addr.txt
192.168.2.1
8.8.8.8
10.9. 9.9
4.4.4.4
9.9.9.9
1.1.1.1
Running and outputting

Answer 2

As one of the options

for line in `cat host.txt` ; do ping -c 1 $line |awk '{print $4 $6}'| head -n2|tail -n 1; done

Answer 3

fping -e -f host
8.8.8.8 is alive (45.9 ms)
4.2.2.4 is alive (62.0 ms)

8.8.8.8 is alive (45.9 ms)
4.2.2.4 is alive (62.0 ms)
