Hello, I'm trying to find a file within a folder, but the file names aren't exact. The beginning contains a random number and the second contains a hash string separated by a period. I've produced the following code, but it takes far too long to execute for my planned use. If anyone has a faster method for doing this (including a linux command), I would love to hear how. Example file: 103746383.100740266a1b4bf5d456cb8876be0e4e9662d871 

sub find_hash_core(){
    opendir(DIR,"./");
    @a = readdir(DIR);
    close(DIR);
    foreach (@a) {
        #print "$_";
        if ($_ =~ "100740266a1b4bf5d456cb8876be0e4e9662d871"){
            print "Found Hash!";
        }
    }
}
