use File::Find;
$source = '/somedir';
$somefile = 'somefile.txt';
traverse();
sub traverse {
my %opts = ( wanted => \&eval_files,
);
finddepth(\%opts, $source);
}
sub eval_files {
if (-f && $_ eq $somefile) {
print 'Got ', $_,"\n";
}
}
For each item within a directory, File::Find will invoke the sub &eval_files.
eval_files() does blissfully throw away items that aren't files and will shriek if the
the file matches the given filename. $_ contains magically the name of the current item (dir / file).
