Regarding my \b comment, only my version prints both
(Now I have tested with perl 5.8 and 5.18)
Yes, the boundary \b metacharacter is an anchor and I did not stop to think that it will not be saved as part of the group match.
From perl -ne 'print unless /(\b\w+\b).*\g1/i' to perl -ne 'print unless /\b(\w+)\b.*\b\g1\b/i' would had been a more appropriated suggestion. If your Perl version does not support the \g{} then, there's other bugs to consider.

Hello Folks,
Can some one help me with the removal of duplicate lines from a log file and send it to another log file. It's bit complicated as two lines are same but only difference is the timestamp, but some lines are uniq. Line has been seperated by colon's.

hi to all
Does anyone know if there's a way to remove duplicate lines which we consider the same only if they have the first and the second column the same?
For example I have :
us2333 bbb 5
us2333 bbb 3
us2333 bbb 2
and I want to get
us2333 bbb 10
The thing is I cannot... (2 Replies)

moose::autobox
Moose::Autobox(3) User Contributed Perl Documentation Moose::Autobox(3)NAME
Moose::Autobox - Autoboxed wrappers for Native Perl datatypes
SYNOPOSIS
use Moose::Autobox;
print 'Print squares from 1 to 10 : ';
print [ 1 .. 10 ]->map(sub { $_ * $_ })->join(', ');
DESCRIPTION
Moose::Autobox provides an implementation of SCALAR, ARRAY, HASH & CODE for use with autobox. It does this using a hierarchy of roles in a
manner similar to what Perl 6 might do. This module, like Class::MOP and Moose, was inspired by my work on the Perl 6 Object Space, and the
'core types' implemented there.
A quick word about autobox
The autobox module provides the ability for calling 'methods' on normal Perl values like Scalars, Arrays, Hashes and Code references. This
gives the illusion that Perl's types are first-class objects. However, this is only an illusion, albeit a very nice one. I created this
module because autobox itself does not actually provide an implementation for the Perl types but instead only provides the 'hooks' for
others to add implementation too.
Is this for real? or just play?
Several people are using this module in serious applications and it seems to be quite stable. The underlying technologies of autobox and
Moose::Role are also considered stable. There is some performance hit, but as I am fond of saying, nothing in life is free. Note that this
hit only applies to the use of methods on native Perl values, not the mere act of loading this module in your namespace.
If you have any questions regarding this module, either email me, or stop by #moose on irc.perl.org and ask around.
Adding additional methods
Moose::Autobox asks autobox to use the Moose::Autobox::* namespace prefix so as to avoid stepping on the toes of other autobox modules.
This means that if you want to add methods to a particular perl type (i.e. - monkeypatch), then you must do this:
sub Moose::Autobox::SCALAR::bar { 42 }
instead of this:
sub SCALAR::bar { 42 }
as you would with vanilla autobox.
METHODS
mixin_additional_role ($type, $role)
This will mixin an additional $role into a certain $type. The types can be SCALAR, ARRAY, HASH or CODE.
This can be used to add additional methods to the types, see the examples/units/ directory for some examples.

BUGS
All complex software has bugs lurking in it, and this module is no exception. If you find a bug please either email me, or add the bug to
cpan-RT.
