Perl switches (perldoc perlrun):
"-n" reads lines from @ARGV (that is INPUTFILE) to $_ and "-l" removes and adds (when printing) newline chars. "-a" splits $_ to @F array according to a regex from "-F" option
"grep {! RE} @F" filters all elements from the array (elements are strings - "{123, 0, 111}" and so on) where it's not true that 0 is a "word" (not in any numbers like 10, 101, etc.).
Then we join the ready list to a string with ", " as the separator and print it.
I am trying to use a script to replace the header of each file, whose filename are stored within the array $test, using the sed command within a Perl script as follows:

je::object::array
JE::Object::Array(3pm) User Contributed Perl Documentation JE::Object::Array(3pm)NAME
JE::Object - JavaScript Array object class
SYNOPSIS
use JE;
use JE::Object::Array;
$j = new JE;
$js_array = new JE::Object::Array $j, 1, 2, 3;
$perl_arrayref = $js_array->value; # returns [1, 2, 3]
$js_array->[1]; # same as $js_array->value->[1]
"$js_array"; # returns "1,2,3"
DESCRIPTION
This module implements JavaScript Array objects.
The "@{}" (array ref) operator is overloaded and returns a tied array that you can use to modify the array object itself. The limitations
and caveats mentioned in "JE::Object/"USING AN OBJECT AS A HASH"" apply here, too.
METHODS
See JE::Types for descriptions of most of the methods. Only what is specific to JE::Object::Array is explained here.
$a = JE::Object::Array->new($global_obj, @elements)
$a = JE::Object::Array->new($global_obj, $length)
$a = JE::Object::Array->new($global_obj, @elements)
This creates a new Array object.
If the second argument is an unblessed array ref, the elements of that array become the elements of the new array object.
If there are two arguments and the second is a JE::Number, a new array is created with that number as the length.
Otherwise, all arguments starting from the second one become elements of the new array object.
$a->value
This returns a reference to an array. This is a copy of the Array object's internal array. If you want an array through which you can
modify the object, use @$a.
