UNIX for Dummies Questions & Answers

Okay,
this may turn out to be something quite simple, but I haven't found the answer so far:

1) Is it possible to retrieve a list of user(ID) file permissions?

and then...

2) What is the most efficient way to create an alert/error message when/if those file permissions are denied? Would this require a simple Perl script, or something affiliated with ROOT?

Kinda itchin' to get this resolved as soon as possible.

I'll be happy to provide further information if necessary.

Thanks

1) Is it possible to retrieve a list of user(ID) file permissions?

See the man page for the find command
$ find . -user username -ls
username can be either a username or a numeric user ID.



2) What is the most efficient way to create an alert/error message when/if those file permissions are denied?

The system will provide a error message - what more do you want?
$ls -l /var/adm/sulog
-rw------- 1 root root 71386 Aug 1 12:00 /var/adm/sulog
$ cat /var/adm/sulog
/var/adm/sulog: Permission denied

Okay, I'll look into that.
What I really want to do: How can I get Perl to return the unix permissions of a directory?

Thanks
