perl - Pick line with highest value -


referring code below:

how pick sample has highest value , output whole line.

 sample      value      sequence  mir1        23213      atatgcgctcg  mir1        324235     atatctcgct  mir1        3453       tctgctcg  mir2        343        tctctgag  mir2        34535      tctct  mir2        4324       tctgagag  ...

output:

 mir1        324235     atatctcgct  mir2        34535      tctct

i guess sorting in excel, there way in perl or in command line?

an awk solution:

awk 'nr>1{ if (a[$1]<$2) {a[$1]=$2;b[a[$1]]=$0} else a[$1]} end {for (i in a) print b[a[i]]}' file  mir1        324235     atatctcgct  mir2        34535      tctct
