Power Help with Ping Script and AWK
Hey Guys,

First time posting here. I keep getting back here on my google searches to help me in my scripting quest.
Can i ask for some guidance please?

I acquired a script, from these forums in fact that pings a list of IPs/Hostnames. Works a treat. Echos results to a file with the value (IP/Hostname) pinged.

Before
Code:
device1      1.1.1.1
device2      2.2.2.2

Script
Code:
#! /bin/sh
IPLIST=`less ./devices.txt | awk '{print $2}'`
for ip in $IPLIST
do
  echo $ip
  ping -c 2 $ip >>device-log.txt
  if [ $? -eq 0 ]
  then
     echo $ip "PINGS">>pingresultsace-device.txt
  else
    echo $ip "DOESN'T PING">>pingresultsace-device.txt
 fi
done


The output is
Code:
1.1.1.1 PINGS
2.2.2.2 DOESN'T PING

What i would really like is to put the entire line, or parts of it to produce. By parts of it i mean, using the AWK command or similar to select the fields to echo.

Code:
device1      1.1.1.1 PINGS
device2      2.2.2.2 DOESN'T PING

Thanks All

igawk

IGAWK(1)							 Utility Commands							  IGAWK(1)

NAME

       igawk - gawk with include files

SYNOPSIS

       igawk [ all gawk options ] -f program-file [ -- ] file ...
       igawk [ all gawk options ] [ -- ] program-text file ...

DESCRIPTION

       Igawk is a simple shell script that adds the ability to have ``include files'' to gawk(1).

       AWK programs for igawk are the same as for gawk, except that, in addition, you may have lines like

	      @include getopt.awk

       in your program to include the file getopt.awk from either the current directory or one of the other directories in the search path.

OPTIONS

       See gawk(1) for a full description of the AWK language and the options that gawk supports.

EXAMPLES

       cat << EOF > test.awk
       @include getopt.awk

       BEGIN {
	    while (getopt(ARGC, ARGV, "am:q") != -1)
		 ...
       }
       EOF

       igawk -f test.awk
