You could probably first just slurp lines one and two into an array:
open FH, $file or die "Can't open $file: $!";
my @lines = (<FH>)[0,1];
close FH;
If the fields are fixed length, you can separate them with unpack. If they are whitespace delimited, split /\s+/ will do to break up the line. Otherwise, you might need a hefty regex. But it looks like they're whitespace delimited, so you could do:
my %data = ();
# define all field names
my @line1_fields = qw/ batch_suffix_id associated_operations /;
my @lines2_fields = qw/ record_created record_created_date ... /;
@data{ @line_1_fileds } = split /\s+/, $lines[0];
@data{ @line_2_fields } = split /\s+/, $lines[1];
There, now you have a hash with all your field names.
