                          ABSTRACT

          The program described in this paper,  access,
     was  written  to  help users interpret the permis-
     sions set on their files by showing in  a  concise
     format  who may read, write, execute, and remove a
     given file.  Rather than simply reporting the per-
     missions  on  the  file  itself, access takes into
     account the permission bits set on the directories
     which lead to the file.  This results in a correct
     listing  of  exactly  who  may  access  the  file,
     whereas  reporting  the  permissions  on  the file
     alone does not.

October 1984
