Here is a quick and dirty script... if you want just the "Account Not Registered" and not the whole "F - Account Not Registered", you will need to parse the last field.

Please note: I am assuming a comma is the field delimiter.

#!/usr/bin/perl use strict; use warnings; my $Data; while(<DATA>) { chomp; @_=split(','); $Data->{$_[1]}->{$_[3]}++; } foreach my $User (sort keys %{$Data}) { print 'User: ',$User,"\n"; foreach my $Error (sort keys %{$Data->{$User}}) { print ' [',$Error,'] happened ',$Data->{$User}->{$Error},' time(s +)',"\n"; } } __DATA__ 2004/09/01:10:37:57,cbt54632,,F - Account Not Registered 2004/09/01:10:37:57,cbt99999,,F - Account Not Registered 2004/09/01:10:37:57,cbt54632,,A - Some Other Error 2004/09/01:10:37:57,cbt99999,,B - Yet Another Error 2004/09/01:11:37:57,cbt54632,,F - Account Not Registered

I hope this helps!
