'read' Permission To Everyone On A file

• Create a file with 'read' access to everyone, in our home directory:
  • Create the file in the home directory.
  • Give 'read' access to "User-owner", "Group-owner", and "Others":
    
    chmod a+r <file_name>
    
    (Note: 'a' is a short-hand for "all" - i.e. "User-owner", "Group-owner" and "Others")
  • Give 'x' access to our home directory, so the Users will be able to reach for files in it:
    
    chmod a+x ~
    
    (Note: '~' is a short-hand for our home directory)
