You don’t have read permission for that file.

Simple self-answering test:

  • Create an empty file

    touch ~/bar
    

    enter image description here

  • Remove the read permissions

    chmod -r ~/bar

You can provide others read access to that file so that it wont display.

sudo chmod o+r <your_filename>
