I am just trying to create a funny code. It accepts two arguments directory to search and filename
It will work on Unix. you can make it work on Windows by reversing the slash.
Just try perl <script name> <dir name> <file name>

my ($mydir, $word) = (@ARGV);
opendir(DIR, "$mydir") || warn "can't opendir : $!";
@dots = grep { /\w/ } readdir(DIR);
closedir DIR;

foreach $dir_tree(@dots)
{
        #print "$dir_tree\n";
        opendir(DIR, "$dir_tree");
        @dots1 = grep { /\w/ } readdir(DIR);
        foreach $dir_tree1(@dots1)
        {
                push @dots, "$dir_tree/$dir_tree1";
                my $name = "$dir_tree/$dir_tree1";
                print "$dir_tree/$dir_tree1\n" if ($name =~ m/\Q$word\
+E/is);
        }

        closedir DIR;

}
