The reason is the use of 'chomp' before the 'split' function.
The perldoc page of split says
Quote:
Splits the string EXPR into a list of strings and returns that list. By default, empty leading fields are preserved, and empty trailing ones are deleted. (If all fields are empty, they are considered to be trailing.)
When you remove the last '\n', split omits those last empty fields. but it doesn't if you keep it, as you can see in my example.

Hi! I'm doing bash shell scripting and would like to know if bash had something similar to perl's split function? Ultimately, I want to split two strings (delimeter = '.') and compare each of their values. Thus, I figured putting them in an array would be easiest.
So i.e.:

perl::critic::policy::builtinfunctions::prohibitstringysplit
Perl::Critic::Policy::BuiltinFunctions::ProhibitStringySUser(Contributed Perl DocPerl::Critic::Policy::BuiltinFunctions::ProhibitStringySplit(3pm)
NAME
Perl::Critic::Policy::BuiltinFunctions::ProhibitStringySplit - Write "split /-/, $string" instead of "split '-', $string".
AFFILIATION
This Policy is part of the core Perl::Critic distribution.
DESCRIPTION
The "split" function always interprets the PATTERN argument as a regular expression, even if you specify it as a string. This causes much
confusion if the string contains regex metacharacters. So for clarity, always express the PATTERN argument as a regex.
$string = 'Fred|Barney';
@names = split '|', $string; #not ok, is ('F', 'r', 'e', 'd', '|', 'B', 'a' ...)
@names = split m/[|]/, $string; #ok, is ('Fred', Barney')
When the PATTERN is a single space the "split" function has special behavior, so Perl::Critic forgives that usage. See "perldoc -f split"
for more information.
CONFIGURATION
This Policy is not configurable except for the standard options.
