#!/usr/bin/perl use strict; use warnings; { local $/ = '>Group'; while (<DATA>) { chomp; print ">Group$_" if tr/\n// > 2; } } __DATA__ >Group 42 0 25ap, >name_06-T_1_0... at 92.00% 1 28ap, >name_06-T_1_0... * >Group 43 0 28ap, >name_07-N_1_0... * >Group 44 0 29ap, >name_07-N_1_0... * >Group 45 0 25ap, >name_03-T_1_0... * 1 25ap, >name_06-T_1_0... at 100.00% 2 25ap, >name_07-N_1_0... at 100.00% 3 25ap, >name_11-N_1_0... at 100.00% 4 25ap, >name_14-T_1_0... at 100.00%
prints
>Group 42 0 25ap, >name_06-T_1_0... at 92.00% 1 28ap, >name_06-T_1_0... * >Group 45 0 25ap, >name_03-T_1_0... * 1 25ap, >name_06-T_1_0... at 100.00% 2 25ap, >name_07-N_1_0... at 100.00% 3 25ap, >name_11-N_1_0... at 100.00% 4 25ap, >name_14-T_1_0... at 100.00%
If you want to separate the records with a newline in the output, add a newline in the print. print ">Group$_\n" if tr/\n// > 2;
