The following BASH script uses the ping command and computes the average PING to a domain via awk text processing.
1 2 3 4 5 6 7 8 | #!/bin/bash if [[ -z $1 ]]; then echo Usage: $0 domain exit 1 fi ping -c 3 $1 | head -4 | tail -3 | awk 'BEGIN{a=0;c=0} {a+=substr($8,6);c+=1} END{print(a)/c;}' |
#!/bin/bash
if [[ -z $1 ]]; then
echo Usage: $0 domain
exit 1
fi
ping -c 3 $1 | head -4 | tail -3 | awk 'BEGIN{a=0;c=0} {a+=substr($8,6);c+=1} END{print(a)/c;}'The ping command we can specify the number of times via -C option:
1 2 3 4 5 6 7 8 | PING helloacm.com(XXXX) 56 data bytes 64 bytes from XXXX: icmp_seq=1 ttl=56 time=10.4 ms 64 bytes from XXXX: icmp_seq=2 ttl=56 time=10.6 ms 64 bytes from XXXX: icmp_seq=3 ttl=56 time=10.6 ms --- helloacm.com ping statistics --- 3 packets transmitted, 3 received, 0% packet loss, time 2003ms rtt min/avg/max/mdev = 10.400/10.592/10.698/0.180 ms |
PING helloacm.com(XXXX) 56 data bytes 64 bytes from XXXX: icmp_seq=1 ttl=56 time=10.4 ms 64 bytes from XXXX: icmp_seq=2 ttl=56 time=10.6 ms 64 bytes from XXXX: icmp_seq=3 ttl=56 time=10.6 ms --- helloacm.com ping statistics --- 3 packets transmitted, 3 received, 0% packet loss, time 2003ms rtt min/avg/max/mdev = 10.400/10.592/10.698/0.180 ms
We use the head and tail command the get the lines from 2 to 4 and use awk to get the average of the ping/latency time.
