file link count
a portion of the internal information used to identify a file in the OSS file system (an
inode number). The two identifiers are not comparable.
file link count. The total number of directory entries for an Open System Services (OSS)
file within an HP NonStop™ node.
file mode. For an Open System Services (OSS) process, a field in the stat structure for a
specific file that describes the type and characteristics of the file and contains the
access permission bits for the file.
file mode creation mask. A mask associated with an Open System Services (OSS)
process and used when the process creates a file. Bits set in this mask are cleared in
the access permission bits for the file.
filename. In the Open System Services (OSS) environment, a component of a pathname
containing any valid characters other than slash (/) or null. See also file name.
file name. A string of characters that uniquely identifies a file.
In the PC environment, file names for disk files normally have at least two parts (the
disk name and the file name); for example, B:MYFILE.
In the Guardian environment, disk file names include a node name, volume name,
subvolume name, and file identifier; for example, \NODE.$DISK.SUBVOL.MYFILE.
In the Open System Services (OSS) environment, a file is identified by a pathname; for
example, /usr/john/workfile. See also filename.
file other class. The property of an Open System Services (OSS) file indicating access
permissions for a process related to the user ID and group ID of the process. A
process is in the file other class of a file if both:
•
The process is not a member of the file owner class for the file.
•
The process is not a member of the file group class for the file.
file owner class. The property of an Open System Services (OSS) file indicating access
permissions for a process related to the user ID of the process. A process is in the file
owner class of a file if the process has an effective user ID that is the same as the user
ID (owner) associated with the file.
file permission bits. Information about an Open System Services (OSS) file that is used,
along with other information, to determine whether a process or user has read, write, or
execute/search permission to that file. The bits are divided into three parts: owner,
group, and other. Each part is used with the corresponding file class of processes.
file serial number. A number that uniquely identifies a file within its file system.
fileset. In the Open System Services (OSS) environment, a set of files with a common
mount point within the file hierarchy. A fileset can be part or all of a single virtual file
system.
