 assuming fileA contain the data below could help with this

perl -lane '$l=$_, ($a,$b,$c,$d)= split(/\./,$F[0]),print $d' fileA

fileA
===
192.68.45.718 daskjaskjf asdfjkasjf asfkasfklh
192.68.34.62 ADKDAK Dkkslaslk jjsdkdldj
192.68.23 INEED HELP PLEASE
192.68.67.4 dkasdfkl kasfkasfkakf
192.68.4.97 flaskfk asfkfafv asf

How do I modify the command line code above to get this below : print
lines where the last quadrant is even

123.68.45.718 daskjaskjf asdfjkasjf asfkasfklh
192.68.34.62 ADKDAK Dkkslaslk jjsdkdldj
192.68.67.4 dkasdfkl kasfkasfkakf


Thanks
Any other ideas will be appreciated.

Exactly the same way as is currently being discussed in the thread
"regex back matching" which _YOU_ started.
Why are you kicking off another thread with the identical topic while
there are still open question in the first one? Do you want to
re-discuss the same old questions again?
