hi all.

have file below

5 2.1.4-1.0.0
5 2.1.4-1.0.0
5 2.1.4-1.0.0
5 2.1.4-1.0.0
5 2.1.4-1.0.0
5 2.1.4-1.0.0
5 2.1.4-1.0.0
5 2.1.4-1.0.0
5 2.1.4-1.0.0
5 2.1.4-1.0.0
5 2.1.4-1.0.0
5 2.1.4-1.0.0
5 2.1.4-1.0.0
5 2.1.4-1.0.0
5 2.1.4-1.0.0
4 0.1.9-0.5.1
5 2.1.4-1.0.0
5 2.1.5-1.0.0
5 2.1.4-1.0.0
5 2.1.4-1.0.0

want awk tell me on few lines, lines different others.
output unique , non-duplicated lines.

example.
above gets be
4 0.1.9-0.5.1
5 2.1.4-1.0.0
5 2.1.5-1.0.0

, other lines discarded.
hope makes sense.

kind regards.
