Release notes for 0.41


This module doesn't use rsync, so it works with sudo and Windows, too. And it is also possible to use it with templates. If a file should be used as a template, you have to name it somefile.ext.tpl.

task "prepare", "mysystem01", sub {

    # upload directory recursively to remote system.
    sync_up "/local/directory", "/remote/directory";

    sync_up "/local/directory", "/remote/directory", {

        # setting custom file permissions for every file
        files => {
            owner => "foo",
            group => "bar",
            mode  => 600,

        # setting custom directory permissions for every directory
        directories => {
            owner => "foo",
            group => "bar",
            mode  => 700,

    # download a directory recursively from the remote system to the local machine
    sync_down "/remote/directory", "/local/directory";

To get a list of all returned information:

use Data::Dumper;
my %hw_info = Rex::Hardware->get(qw/VirtInfo/);
print Dumper( \%hw_info );

To get the hypervisor:

task "info", "mysystem01", sub {
    my %hw_info = Rex::Hardware->get(qw/VirtInfo/);

    say "Role: " . $hw_info{VirtInfo}->{virtualization_role};
    say "Type: " . $hw_info{VirtInfo}->{virtualization_type};
