14975:50417 1:N:0:CGATGT - chr11 108607098 GCTAGCTTACAGGTCACCTTGCTTGGTGTGGACAGT JJIIJJJGGGIJHHHFJJJIJJJHHHHHFFFFFCCC 0 33:A>T,34:G>C 14975:50417 2:N:0:CGATGT + chr11 89267281 TCATGAAGTATAAAGTTACAGGGTGGTGATGTGATT CCCFFFFFBHHHFIJIIIIIIIJAFH<FFHIGIIIJ 0
my code shud not be printing this line because here both fields are equal
but it does because there are sm extra tabs.
how do i tell it to compare only those fields starting with chr in a given line?
