I’m trying to modify someone perl script to fix a bug. The piece of code checks that the zone name you want to add is unique. However, when the code runs, it finds a partial match using grep, and decides it already exists, so the “create” command exits.

This returns 0 even when it does not delete any files.
Is it because -print returns 0?

extutils::typemaps::outputmap
ExtUtils::Typemaps::OutputMap(3pm) Perl Programmers Reference Guide ExtUtils::Typemaps::OutputMap(3pm)
NAME
ExtUtils::Typemaps::OutputMap - Entry in the OUTPUT section of a typemap
SYNOPSIS
use ExtUtils::Typemaps;
...
my $output = $typemap->get_output_map('T_NV');
my $code = $output->code();
$output->code("...");
DESCRIPTION
Refer to ExtUtils::Typemaps for details.
METHODS
new
Requires "xstype" and "code" parameters.
code
Returns or sets the OUTPUT mapping code for this entry.
xstype
Returns the name of the XS type of the OUTPUT map.
cleaned_code
Returns a cleaned-up copy of the code to which certain transformations have been applied to make it more ANSI compliant.
targetable
This is an obscure optimization that used to live in "ExtUtils::ParseXS" directly.
In a nutshell, this will check whether the output code involves calling "set_iv", "set_uv", "set_nv", "set_pv" or "set_pvn" to set the
special $arg placeholder to a new value AT THE END OF THE OUTPUT CODE. If that is the case, the code is eligible for using the
"TARG"-related macros to optimize this. Thus the name of the method: "targetable".
If the optimization can not be applied, this returns undef. If it can be applied, this method returns a hash reference containing the
following information:
type: Any of the characters i, u, n, p
with_size: Bool indicating whether this is the sv_setpvn variant
what: The code that actually evaluates to the output scalar
what_size: If "with_size", this has the string length (as code,
not constant)
