Can you explain the comparison that you are looking for?
Is it one to one:
Is it one to many:
Or is it many to many, in which case a database is much more efficient....
None of your example compare anything, "=" is the assignment operator.
To compare numbers use "==" to compare strings use "eq", of course sometimes its never that simple but it looks like it would be in this case if the examples are what is really being compared. There are also modules that compare arrays, one I believe is called Array::Compare
I have searched and found a few threads that have dealt with this, but the examples I've tried haven't seemed to help.
I am monitoring our database log for high checkpoints.
I can parse out the checkpoint value which can be anywhere from zero into a 3 digit number.

I'm writing a shellscript that monitors the price of a watch. If the prices changes, it should email me. The body of the email will show the old price and the new price.

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.
