Fault Notification
- If you choose, the print service can notify you when it detects a printer
fault. By default, printer fault notification messages are written to the
superuser's console.
fdformat
- The fdformat command is used to format diskettes. fdformat
formats and verifies each track on the diskette and terminates if it finds any
bad sectors. By default, fdformat formats a high density diskette with
a capacity of 1.44 Mbytes. A SunOSTM label is written onto the
diskette unless the -d or -t options are specified.
File
- A file is a named collection of related data stored on a disk.
File Contents
- The contents of a UNIX file are specified by the type of file. For example,
data files are generally binary format, and text files are generally ASCII
format. You may use the file command to ask for a file's content type.
File Owner
- The file owner is the user who creates the file or directory. When you create
a new file or directory, it is owned by you. The owner of the file is also
referred to as the user.
File Resource
- A file resource refers to a directory or file system. For example, the /opt
directory is considered a file resource.
File System
- The file system is a hierarchy of directories, subdirectories, and files that
are usually organized or grouped together for a specific purpose.
find
- The find command searches directories for files that match a given
set of criteria. A file can be found by searching for its name, size, creation
date, or other criteria. Multiple criteria may be joined together to search for
specific individual files.
Firmware
- Firmware programs are permanently installed in a chip. The Boot PROM and
non-volatile random access memory (NVRAM) chips are examples of firmware. Some
parts of the programs can be upgraded and placed on newer systems.
FNS
- The FNS (Federated Naming Service) provides a method for federating multiple
naming services under a single, simple interface for naming and directory
operations. Naming services that can be linked with FNS include: network
information services plus (NIS+), network information services (NIS), files,
domain name services (DNS), and X.500/lightweight directory access protocol (LDAP).
Fork
- fork (or spawn) is an operating system routine that creates a new
process. The new process (called the child process) is an exact copy of the
forking process (called parent process).
format
- The format command is used to perform low-level maintenance
operations on disk drives. format enables you to format, label, repair,
and analyze disks on your system. format is unlike other disk
maintenance programs in that it can be run while the system is running in
multiuser mode.
Frame Buffer
- The frame buffer is a portion of memory that serves as the pixelmap of the
image being displayed. In some systems this frame buffer resides in several
interchangable memory areas (pages). It is usually in a permanently allocated
portion of memory which can be directly accessed by the video controller,
without the system bus being tied up.
Free Hog
- The free hog partition is used to modify the partitions on a file system.
This partition automatically grows or shrinks as you modify the size of other
partitions on the disk. If the free hog partition is zero, you must shrink
another partition to create some space in the free hog partition before you can
increase the size of the other partition.
ftp
- The ftp command is the user interface to the Internet standard File
Transfer Protocol (FTP). ftp is used to transfer files to and from
a remote network site.
Full Dump
- A full dump backs up the contents of an entire file system; full dumps are
performed at lengthy intervals.
Full Resynchronization
- In the network information services plus
(NIS+) environment, a full
resynchronization or "resync" happens if the master server receives a
timestamp that is earlier than the earliest timestamp recorded in the
transaction log from a replica. A resync downloads to the replica all of the
objects and information stored in the master.
