Lightbulb Grep values on alternate lines
Hi,

I have a file like

Code:
2011|ACC|.*
2013|ACC|.*
2011|ACCC|.*
2013|ACCC|.*
2013|ACCV|.*
2011|ADB|.*
2013|ADB|.*
2011|ADBC|.*
2013|ADBC|.*
2011|AIA|.*
2013|AXJ|.*
2013|NNN|.*

.* represnts any alphanumeric characters after this part of the string

I need a code to return only the rows which has same value on the second field but different value on first


for eg:
for above piece of data, code should return

Code:
2011|ACC|.*
2013|ACC|.*
2011|ACCC|.*
2013|ACCC|.*
2011|ADB|.*
2013|ADB|.*
2011|ADBC|.*
2013|ADBC|.*


any suggestions ?

SCSI_TEMPERATURE(8)						     SG3_UTILS						       SCSI_TEMPERATURE(8)

NAME

       scsi_temperature - fetch the temperature of a SCSI device

SYNOPSIS

       scsi_temperature [--help] [--verbose] DEVICE [DEVICE]*

DESCRIPTION

       This  bash  shell script calls the sg_logs utility on each given DEVICE in order to find the device's temperature. The Temperature log page
       is checked first and if it is not available then the Informational Exceptions log page is checked.

OPTIONS

       Arguments to long options are mandatory for short options as well.

       -h, --help
	      print out the usage message then exit.

       -v, --verbose
	      increase level or verbosity.

EXIT STATUS

       The exit status of this script is 0 when it is successful. Otherwise the exit status is that of the last sg_logs utility  called.  See  the
       sg3_utils(8) man page.
