'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)
