Dear Wise Monks
I am having trouble getting an anonymous sub routine to execute.
#!/usr/bin/perl -w
use strict;
my %new_resolvers = (
'dns-one' => [
"127.0.0.1\tdns-apple"
, "127.0.0.2\tdns-banana"
, "127.0.0.3\tdns-shoe"
]
, 'dns-extern' => [
sub {
my $ip = shift or die "you need to pass in IP address";
my @array;
open ( PIPE, "./get_resolvers_for_client.sh|" )
or die __FILE__ . " [" . __LINE__ . "] could not open get_re
+solvers_for_client.sh:$!";
while ( <PIPE> ) {
chomp;
last if /not a one of our IP addresses/;
push ( @array, $_ );
}
return reverse @array;
}
]
);
for my $dns_server ( keys %new_resolvers ) {
print "getting new resolvers for dns server $dns_server\n";
my $resolvers = join "\n", @{$new_resolvers{$dns_server}}
+;
print "$resolvers\n\n";
}
When I run my script I get this output ...
getting new resolvers for dns server dns-extern
CODE(0x92fe808)
getting new resolvers for dns server dns-one
127.0.0.1 dns-apple
127.0.0.2 dns-banana
127.0.0.3 dns-shoe
What am I doing wrong here? How do I invoke the anonymous sub? Thank you.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).

Want more info? How to link
or How to display code and escape characters
are good places to start.
