The dot pattern is because it's being executed, but it doesn't have the perms to do so yet, which is why I'm trying to prepend chmod before executing it
Understood. What I was indicating was that if the subdirectory foo/x.mak exists it will be matched if ./x.mak is used where if \./x.mak is used it will not.
I guess actually both dots in the pattern should be escaped for correctness:

lwp::robotua
LWP::RobotUA(3) User Contributed Perl Documentation LWP::RobotUA(3)NAME
LWP::RobotUA - A class for Web Robots
SYNOPSIS
require LWP::RobotUA;
$ua = new LWP::RobotUA 'my-robot/0.1', 'me@foo.com';
$ua->delay(10); # be very nice, go slowly
...
# just use it just like a normal LWP::UserAgent
$res = $ua->request($req);
DESCRIPTION
This class implements a user agent that is suitable for robot applications. Robots should be nice to the servers they visit. They should
consult the /robots.txt file to ensure that they are welcomed and they should not make requests too frequently.
But, before you consider writing a robot take a look at <URL:http://info.webcrawler.com/mak/projects/robots/robots.html>.
When you use a LWP::RobotUA as your user agent, then you do not really have to think about these things yourself. Just send requests as
you do when you are using a normal LWP::UserAgent and this special agent will make sure you are nice.
METHODS
The LWP::RobotUA is a sub-class of LWP::UserAgent and implements the same methods. In addition the following methods are provided:
$ua = LWP::RobotUA->new($agent_name, $from, [$rules])
Your robot's name and the mail address of the human responsible for the robot (i.e. you) are required by the constructor.
Optionally it allows you to specify the WWW::RobotRules object to use.
$ua->delay([$minutes])
Set the minimum delay between requests to the same server. The default is 1 minute.
$ua->use_sleep([$boolean])
Get/set a value indicating whether the UA should sleep() if requests arrive too fast (before $ua->delay minutes has passed). The
default is TRUE. If this value is FALSE then an internal SERVICE_UNAVAILABLE response will be generated. It will have an Retry-After
header that indicates when it is OK to send another request to this server.
$ua->rules([$rules])
Set/get which WWW::RobotRules object to use.
$ua->no_visits($netloc)
Returns the number of documents fetched from this server host. Yes I know, this method should probably have been named num_visits() or
something like that. :-(
$ua->host_wait($netloc)
Returns the number of seconds (from now) you must wait before you can make a new request to this host.
$ua->as_string
Returns a string that describes the state of the UA. Mainly useful for debugging.
