It's still not clear enough.

Ok, let's do this - you have this file:

Code:
[root@]# cat a.txt
a;b;c;64O
a;b;c;d;ee;f

Just describe, in simple, plain English, what you want to do with this file.

Keep that Perl code aside for a moment.

perl::critic::policy::variables::prohibitmatchvars

Perl::Critic::Policy::Variables::ProhibitMatchVars(3)	User Contributed Perl Documentation  Perl::Critic::Policy::Variables::ProhibitMatchVars(3)

NAME

       Perl::Critic::Policy::Variables::ProhibitMatchVars - Avoid "$`", "$&", "$'" and their English equivalents.

AFFILIATION

       This Policy is part of the core Perl::Critic distribution.

DESCRIPTION

       Using the "match variables" "$`", $&, and/or "$'" can significantly degrade the performance of a program.  This policy forbids using them
       or their English equivalents.  See perldoc English or PBP page 82 for more information.

       It used to forbid plain "use English;" because it ends up causing the performance side-effects of the match variables.  However, the
       message emitted for that situation was not at all clear and there is now Perl::Critic::Policy::Modules::RequireNoMatchVarsWithUseEnglish,
       which addresses this situation directly.

CONFIGURATION

       This Policy is not configurable except for the standard options.
