• The process’s effective user ID does not match msg_perm.[c]uid and either the
process’s effective group ID matches msg_perm.[c]gid or one of
msg_perm.[c]gid is in the process’s group access list and the appropriate bit of
the ‘‘group’’ portion (00060) of msg_perm.mode is set.
• The process’s effective user ID does not match msg_perm. [c]uid and the
process’s effective group ID does not match msg_perm.[c]gid and neither of
msg_perm.[c]gid is in the process’s group access list and the appropriate bit of
the ‘‘other’’ portion (06) of msg_perm.mode is set.
Otherwise, the corresponding permissions are denied.
metacharacter
A character that has special meaning to the HP-UX shell, as well as to commands such as
ed, find, and grep (see ed(1), find(1), and grep(1)). The set of metacharacters includes:
!, ", &, ’, *, ;, <, >, ?, [, ], ‘, and |. Refer to sh(1) and the related shell manual
entries for the meaning associated with each. See also regular expression.
minor number
A number that is an attribute of special files, specified during their creation and used when-
ever they are accessed, to enable I/O to or from specific devices. This number is passed to
the device driver and is used to select which device in a family of devices is to be used, and
possibly some operational modes. The exact format and meaning of the minor number is
both system and driver dependent. Refer to the System Administrator manuals supplied
with your system for details.
On Series 700 systems, a minor number indicates the device address, function number,
and driver-dependent bits. On Series 800 systems, a minor number is an index into a
table in the kernel.
mode A 16-bit word associated with every file in the file system, stored in the inode. The least-
significant 12 bits of the mode determine the read, write, and execute permissions for the
file owner, file group, and all others, and contain the set-user-ID, set-group-ID, and ‘‘sticky’’
(save text image after execution) bits. The least-significant 12 bits can be set by the
chmod(1) command if you are the file’s owner or the superuser. The sticky bit on a regular
file can only be set by the superuser. These 12 bits are sometimes referred to as permis-
sion bits. The most-significant 4 bits specify the file type for the associated file and are set
as the result of open(2) or mknod(2) system calls.
mountable file system
A removable blocked file system contained on some mass storage medium with its own root
directory and an independent hierarchy of directories and files. See block special file and
mount(1M).
msqid See message queue identifier.
multiuser state
The condition of the HP-UX operating system in which terminals (in addition to the system
console) allow communication between the system and its users. By convention, multiuser
run level is set at state 2, which is usually defined to contain all the terminal processes and
daemons needed in a multiuser environment. Run levels are table driven, and are
specified by init(1M), which sets the run level by looking at the file
/etc/inittab .Do
not confuse the multiuser system with the multiuser state. A multiuser system is a system
which can have more than one user actively communicating with the system when it is in
the multiuser state. The multiuser state removes the single-user restriction imposed by
the single-user state (see single-user state, inittab(4)).
native language
A computer user’s spoken or written language, such as Chinese, Dutch, English, French,
German, Greek, Italian, Katakana, Korean, Spanish, Swedish, Turkish, etc.
Native Language Support (NLS)
A feature of HP-UX that provides the user with internationalized software and the applica-
tion programmer with tools to develop this software.
newline character
The character with an ASCII value of 10 (line feed) used to separate lines of characters. It
is represented by
\n in the C language and in various utilities. The terminal driver
