I have a script that logs into a server and pings several other servers in order to verify IP path between servers.
The output can look like this, if good pings:
Response from 1.1.1.4;_id=0, vlan_prio=0): seq=0 time=91.547 ms.
Response from 1.1.1.4;_id=0, vlan_prio=0): seq=1 time=61.176 ms.
Response from 1.1.1.4;_id=0, vlan_prio=0): seq=2 time=60.904 ms.
I found a thread in this forum (now closed) that allowed for pattern matching on the "packet loss" and to print the previous line (so my log will show IP address as well as result, since this system doesn't include them on the same line.)
Code:
awk '/packet loss/{if (a && a !~ /packet loss/) print a; print} {a=$0}' log_ping.txt
(Thanks Marco!)
But I need an additional snippet in there somehow to EXCLUDE lines that show "0% packet loss"...i.e. only match on lines that show some kind of packet loss. Not 0% packet loss.
In a nutshell, I need to work out how to return the last matching pattern from an awk //,// search. I can bring back the first, but am unsure how to obtain the last, and a simple tail won't work as the match could be over multiple lines.
Secondly I would like some way of pattern matching, a... (10 Replies)
Dear Team,
How do we match two patterns on the same line using awk?Are there any logical operators which i could use in awk like awk '\gokul && chennai\' <filename>
Eg:

aecho
AECHO(1) General Commands Manual AECHO(1)NAME
aecho - send AppleTalk Echo Protocol packets to network hosts
SYNOPSIS
aecho [ -c count ] ( address | nbpname )
DESCRIPTION
aecho repeatedly sends an Apple Echo Protocol (AEP) packet to the host specified by the given AppleTalk address or nbpname and reports
whether a reply was received. Requests are sent at the rate of one per second.
address is parsed by atalk_aton(3). nbpname is parsed by nbp_name(3). The nbp type defaults to `Workstation'.
When aecho is terminated, it reports the number of packets sent, the number of responses received, and the percentage of packets lost. If
any responses were received, the minimum, average, and maximum round trip times are reported.
EXAMPLE
Check to see if a particular host is up and responding to AEP packets:
example% aecho bloodsport
11 bytes from 8195.13: aep_seq=0. time=10. ms
11 bytes from 8195.13: aep_seq=1. time=10. ms
11 bytes from 8195.13: aep_seq=2. time=10. ms
11 bytes from 8195.13: aep_seq=3. time=10. ms
11 bytes from 8195.13: aep_seq=4. time=10. ms
11 bytes from 8195.13: aep_seq=5. time=9. ms
^C
----8195.13 AEP Statistics----
6 packets sent, 6 packets received, 0% packet loss
round-trip (ms) min/avg/max = 9/9/10
OPTIONS -c count
Stop after count packets.
