From Default Perl on OSX, How To Unzip To Folder? - macos

Question

I'm trying to avoid having to include other libraries and keep this simple on OSX, using the default Perl that ships with OSX since Snow Leopard. I'm also trying to avoid shelling out to Bash to run the unzip. I found this example almost works, but dies on this line:
my $fh = IO::File->new($destfile, "w") or die "Couldn't write to $destfile: $!";
with this error:
Couldn't write to /tmp/mytest/Install Norton Security.localized//: Is a directory at test7.pl line 42.
Previously, I zipped the folder "Install Norton Security.localized" to mytest.zip and stuck it in /tmp. I then created a directory /tmp/mytest. Then, I ran this script with
unzip("/tmp/mytest/mytest.zip","/tmp/mytest");
I also did a lint syntax check on the script and it came back okay -- didn't warn me about missing libraries like many other zip libraries for Perl.
What do you suggest is the fix?

This routine works on older OSX and doesn't involve as many lines of code. It also handles subfolders.
#!/usr/bin/perl
use strict;
use warnings;
use Archive::Zip qw(:ERROR_CODES :CONSTANTS);
my $sSource = "/tmp/mytest.zip";
my $sDest = "/tmp/mytest";
x_unzip($sSource,$sDest);
sub x_unzip {
my ($zip_file, $out_file, $filter) = #_;
my $zip = Archive::Zip->new($zip_file);
unless ($zip->extractTree($filter || '', $out_file) == AZ_OK) {
warn "unzip not successful: $!\n";
}
}
