C Shell
The C shell offers features such as aliasing and history, as does the Korn
shell.
cancel
- The cancel command is used to cancel a specific print request that
is waiting in the print queue. cancel permits cancellation of requests
based on their request ID or requests based on the login ID of their owner.
Character Device
- A character device is a device, such as a keyboard, tape drive, Character
Deviceinal, raw partition, or printer, that receives information as a stream of
characters, one character at a time. The characters may be transferred either
bit-by-bit (serial transmission) or byte-by-byte (parallel transmission) but not
in blocks.
Character Special
- A character special file works with devices like Character Specialinals, raw
partitions, and printers, which transfer individual characters rather than
blocks of characters.
checksum
- A checksum is a number that is calculated from the binary bytes of the file.
It is used to dechecksumine if the file contents have changed.
chgrp
- The chgrp command is used to change the group association of a file.
The group may be either a decimal group ID or a group name found in the group ID
file /etc/group.
chmod
- The chmod command is used to change the access permissions of a
file.
chown
- The chown command changes the owner of a file. The owner may be
either a decimal user ID or a login name found in the /etc/passwd file.
Client
- Strictly speaking, a client is a process that communicates with a server
process. The client is commonly used to refer to a host that uses the services
from one or more servers on a network.
Client File
- A client file is a record of the save sets for the client.
Coldstart File
- A coldstart file gives a network information services plus
(NIS+) client a
copy of a directory object that it can use as a starting point for contacting
servers in the NIS+ namespace. The directory object contains the address, public
keys, and other information about the master and replica servers that support
the directory.
Command Mode
- When using the vi editor, the command mode is the mode in which you
can position the cursor and use edit commands to perform various actions. When
you open a file with vi, you are in command mode. All commands are
initiated from command mode.
Common Desktop
Environment
- The Common Desktop Environment
(CDE) is a graphical user interface between
the user and the operating system. It provides built-in menus for users to
select and run utilities and programs without using the Solaris 2.x commands. It
enables users to control multiple working documents or applications on the
screen at the same time.
Compressing
- Compressing is the process of reducing a file's size by applying a
compression algorithm to the content of a file. Compressing is useful when
sending a large file via email; it prevents overflowing the recipient's mail
box.
Concatenate
-
Concatenation is when the output of one or more files or commands are joined
together.
When multiple physical disk slices are combined to create a large metadevice.
Concatenatation
- Concatenate means combining multiple physical slices to create a large
metadevice.
Configuration Cluster
- During system installation with SunInstall(TM),
a configuration cluster refers to a logical grouping of software used to
facilitate installation.
Console
- The console device is the main input/output device that is used to access a
system and display all system messages. This can either be a display monitor and
keyboard or a shell window.
Control Character
- A control character is a character that, in a particular context, initiates,
modifies, or stops an operation.
-
Core Configuration Cluster
- The core configuration contains the software needed to boot and run the
Solaris 2.x environment, which can be used to configure a standalone
system, but not a server. It includes some networking software and the drivers
required to run the OpenWindowsTM environment. It does not include
the OpenWindows software or man pages.
cpio
- The cpio command is a user-level command that is used for backing up
and restoring files from tapes or diskettes. The cpio command does not
recognize file system boundaries; cpio supports multivolume backups.
Credentials
- Credentials are the bundle of numbers that are sent by the principal to the
server to authenticate the principal. A principal's credential is generated and
verified each time the principal makes a network information service plus (NIS+)
request. When a user is logged in to an NIS+ client machine as superuser,
requests for service carries with it the workstation's credentials.
crontab
- The crontab command enables users to modify their crontab
configuration file. This configuration is then executed by the cron
utility at the appropriate times.
cshrc
- The $HOME/.cshrc file is an initialization file that is executed
after the /etc/.login file when a user logs into a C shell. The .cshrc
file is also executed each time a new shell is forked. The file contains
variables and parameters that are local to a specific shell. The $HOME/.cshrc
file is copied from /etc/skel/local.cshrc by admintool when a
new account is created.
CSMA-CD
- Carrier sense, multiple-access with collision detection
(CSMA-CD) is the
method of decsma-cdining which workstation can transmit on the network. Each
workstation listens for a carrier signal on the network. The lack of a carrier
indicates no system is transmitting. Any workstation can transmit when the
network is idle. If two workstations attempt to transmit simultaneously, the
collision detection capability of the network adapters causes both to stop
transmitting. Transmission is resumed once the network is idle.
