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 ?
