You can do better than just take fixed arguments:
#!/usr/bin/perl -w
use strict;
use File::Find;
sub make_wanted {
my ($function, $get_argument_function) = @_;
return sub {
$function->($get_argument_function->());
}
}
sub delete_file_with_user_confirmation {
my ($file_name, $user_input) = @_;
if ($user_input =~ /yes/i) {
unlink($file_name)
or die "Error: no unlink for $file_name: $!";
}
}
sub get_user_input_for_file {
# show full path to user
print "Delete ", $File::Find::name, " (say 'yes' to delete)? ";
my $user_input = <STDIN>;
# but remember we chdir()ed into $File::Find::dir
return $_, $user_input;
}
my @dirs = @ARGV ? @ARGV : (".");
find(make_wanted(\&delete_file_with_user_confirmation,
\&get_user_input_for_file),
@dirs);

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.
