That is not quite what I want to do. These tests (and their results) apply to the user/group id of the process conducting the test. What I'd like to determine is the user/group that owns the file, and what the three different levels of access (world/group/user) are. In other words, rather than finding out if the *current* process can access the file, I'd like to know (in the script) what the full mode of the access to the file is. For a human, it is easy enough to read off this information from the `ls -l' command. To emulate this is in an automated script seems to require a reasonable amount of text processing - which strikes me as rather kludgy!
