Hi Folks!
I have a file like this

000000006    dist:0.0    FILE ./MintRoute/MultiHopWMEWMA.nc LINE:305:1 NODE_KIND:131 nVARs:4 NUM_NODE:66 TBID:733 TEID:758

000000001    dist:0.0    FILE ./WSN-simulator-1.0/gnuplot_i_c.nc LINE:217:3 NODE_KIND:65 nVARs:5 NUM_NODE:66 TBID:375 TEID:401

I want to grep the lines where the second number after "LINE" is greater then e.g. >=4. And the blocks should stay separated with a blank line. Can someone help?
