title: Grant acces to dictionary only via my script
body: <p>I have few directories with files on debian 9 system. I want to disable privilege to read these directories for everyone than owner, but I want to let some users list files in this directories only by my own script in bash.
  I change privileges to directories and to my script but i get "permission denied" when i try using it. I understand why, but cant fix it.</p>
