in reply to Counting keys in a hash

Your code does not even compile. Moreover, the logic with @list is wrong: you should keep all the information in the hash, not just the count. Like this:

#!/usr/bin/perl use warnings; use strict; my %error_count; while (<DATA>) { if (my ($error) = m/\](.*)\(20/) { $error_count{$error}{count}++; $error_count{$1}{list} //= [split /\s+/]; # Only remembers th +e first time. } } for (keys %error_count) { my @list = @{ $error_count{$_}{list} }; print "DEVICE\t--> $list[3]\n"; print "DATE\t--> $list[0] $list[1]\n"; print "TIME\t--> $list[2]\n"; print "ERROR\t--> $_\n"; print "\nThe above error occurred $error_count{$_}{count} times\n" +; } __DATA__ Oct 17 10:35:39 esw001tff2 [Root]IP Spoofing from 255.255.255.255 to 2 +55.255.255.255!
