Script to compare pattern and print a different pattern in each line
Hi,

I am writing a shell script to parse some files, and gather data.
The data in the files is displayed as below.

.......xyz: [1234] abz: [1234]......qrt: [2312]....
.......xyz: [1231] abz: [2414]......qrt: [1231]...

I have tried using awk and cut, but the position of these values keep changing, so I wasn't able to get the required output using awk and split it into columns.
The value before the ":' is always constant, the value in the brackets only keep changing.
I need an option which prints in the following manner based on what is being grepped.
it should be a one liner as it is part of a much bigger script, and it should be able to compare the value in the brackets for "xyz:" and "abz:" and if it is the samee then it should print "qrt: [2312]"

In the above example lines the output should be only "qrt: [2312]" as that is the only line with the matching value in the bracket of "xyz:" and "abz:".

Please help

Thanks

upsc

UPSC(8) 							    NUT Manual								   UPSC(8)

NAME

       upsc - example lightweight UPS client

SYNOPSIS

       upsc -l | -L [host]

       upsc ups [variable]

       upsc -c ups

DESCRIPTION

       upsc is provided as a quick way to poll the status of a UPS server. It can be used inside shell scripts and other programs that need UPS
       data but don't want to include the full interface.

OPTIONS

       -l host
	   List all UPS names configured at host, one name per line. The hostname defaults to "localhost". You may optionally add a colon and a
	   port number.

       -L host
	   As above, list all UPS names configured at host, including their description provided by the remote upsd(8) from ups.conf(5). The
	   hostname defaults to "localhost". You may optionally add a colon and a port number to override the default port.

       -c ups
	   Lists each client connected on ups, one name per line.

       ups
	   Display the status of that UPS. The format for this option is upsname[@hostname[:port]]. The default hostname is "localhost".

       variable
	   Display the value of this variable only. By default, upsc retrieves the list of variables from the server and then displays the value
	   for each. This may be useful in shell scripts to save an additional pipe into grep.

EXAMPLES

       To list all variables on an UPS named "myups" on a host called "mybox", with upsd(8) running on port 1234:

	   $ upsc myups@mybox:1234
	   battery.charge: 100.0
	   battery.voltage: 13.9
	   battery.voltage.nominal: 13.6
	   . . .

       To list the UPSes configured on this system, along with their descriptions:

	   $ upsc -L
	   apc: Back-UPS 500
	   ppro2: Patriot Pro II

       To retrieve the status for all UPSes connected to mybox, using Bourne-shell syntax:

	   $ for UPS in `upsc -l mybox:1234`; do
	       upsc $UPS ups.status
	   done

       To list clients connected on "myups":

	   $ upsc -c myups
	   127.0.0.1
	   ::1
	   192.168.1.2

DIAGNOSTICS

       upsc will either print a list of UPS names, a list of all supported variables and their values on the UPS, or an error message. If you
       receive an error, make sure you have specified a valid UPS on the command line, that upsd(8) is really running on the other host and that
       no firewalls are blocking you.

HISTORY

       Earlier versions of this program used the upsfetch library and UDP sockets to talk to upsd. This version of upsc uses the new upsclient
       library, which only talks TCP. This is why upsct no longer exists.
