But if the file was copied in the home directory by a user or by another program and its rights are very restrictive.
As I read "each file belongs to a specific user and group. Access to the files is controlled by user, group, and what is called other. The term, other, is used to refer to someone who is not the user (owner) of the file, nor is the person a member of the group the file belongs to. When talking about setting permissions for "other" users to use, it is commonly referred to as setting the world execute, read, or write bit since anyone in the world will be able to perform the operation if the permission is set in the other category. "
let's say that the user john belong to temp group and
in /export/home/john we have a file script.sh
-rw------- 1 root root 14233 Apr 24 10:32 script.sh
=> user john has NO rights to read/execute/modify script.sh file because the owner of the file is root and group also is root.
That's what I mean and the question is: is this possible to find out these kind of files for each user from /export/home?
Thanks.
regards,
catalin

strmode
STRMODE(3) BSD Library Functions Manual STRMODE(3)
NAME
strmode -- convert inode status information into a symbolic string
LIBRARY
Standard C Library (libc, -lc)
SYNOPSIS
#include <string.h>
void
strmode(int mode, char *bp);
DESCRIPTION
The strmode() function converts a file mode (the type and permission information associated with an inode, see stat(2)) into a symbolic
string which is stored in the location referenced by bp. This stored string is eleven characters in length plus a trailing NUL.
The first character is the inode type, and will be one of the following:
- regular file
b block special
c character special
d directory
l symbolic link
p fifo
s socket
w whiteout
? unknown inode type
The next nine characters encode three sets of permissions, in three characters each. The first three characters are the permissions for the
owner of the file, the second three for the group the file belongs to, and the third for the ``other'', or default, set of users.
Permission checking is done as specifically as possible. If read permission is denied to the owner of a file in the first set of permis-
sions, the owner of the file will not be able to read the file. This is true even if the owner is in the file's group and the group permis-
sions allow reading or the ``other'' permissions allow reading.
If the first character of the three character set is an ``r'', the file is readable for that set of users; if a dash ``-'', it is not read-
able.
If the second character of the three character set is a ``w'', the file is writable for that set of users; if a dash ``-'', it is not
writable.
The third character is the first of the following characters that apply:
S If the character is part of the owner permissions and the file is not executable or the directory is not searchable by the owner, and
the set-user-id bit is set.
S If the character is part of the group permissions and the file is not executable or the directory is not searchable by the group, and
the set-group-id bit is set.
T If the character is part of the other permissions and the file is not executable or the directory is not searchable by others, and the
``sticky'' (S_ISVTX) bit is set.
s If the character is part of the owner permissions and the file is executable or the directory searchable by the owner, and the set-
user-id bit is set.
s If the character is part of the group permissions and the file is executable or the directory searchable by the group, and the set-
group-id bit is set.
t If the character is part of the other permissions and the file is executable or the directory searchable by others, and the ``sticky''
(S_ISVTX) bit is set.
x The file is executable or the directory is searchable.
- None of the above apply.
The last character will always be a space.
