It's may easy or not, based on the special cases you have.
I could show one of the ways:
use strict;
use warnings;
my (%hash, %hash2);
open my $hd, 'log_aa.txt' or die $!;
while(<$hd>) {
next if /^$/;
chomp;
my ($id) = /(\d+)$/;
my $f_name = (split/->/,$_)[-1];
$hash{$id} = $f_name;
}
close $hd;
open $hd, 'log_ca.txt' or die $!;
while(<$hd>) {
next if /^$/;
chomp;
my ($id) = /(\d+)$/;
my $f_name = (split/->/,$_)[-1];
$hash2{$id} = $f_name;
}
close $hd;
for (sort keys %hash) {
print $hash{$_}, "=>", $hash2{$_}, "\n";
}
__END__
Hope this helps.
