Question 1

UNIX-Linux are not case sensitive.

Accepted Answer

UNIX-Linux are case-sensitive operating systems. This means that m, M and MM are treated as three different file names.

Question 2

You can use the ____ command to show the system calendar.
A)clndr
B)syscal
C)cal
D)calendar

Accepted Answer

The "cal" command is used to display the system calendar. The other options (clndr, syscal, and calendar) are not valid commands in most systems.

Question 3

In a peer-to-peer network,the system administrator secures all the information on the network by securing the server.

Accepted Answer

In a peer-to-peer network, there is no central server, so there is no system administrator to secure it. Each individual computer must be secured individually.

Question 4

The UNIX-Linux ____ command displays the system date,which the system administrator maintains.
A)today
B)sysdate
C)system
D)date

Accepted Answer

The "date" command is used to display the system date, which is maintained by the system administrator.

Question 5

UNIX-Linux are ____ systems,which let many people simultaneously access and share the resources of a server computer.
A)superuser
B)peer-to-peer
C)multitasking
D)multiuser

Accepted Answer

UNIX-Linux are multiuser systems, which means that multiple users can access and share the resources of a server computer simultaneously. Each user has their own account and permission level, allowing for secure and efficient collaboration.

Question 6

Most shells keep a list of your recently used commands and allow you to recall a command without retyping it.

Accepted Answer

Most shells have a history feature that keeps a list of recently executed commands, allowing users to easily recall and reuse them without retyping.

Question 7

Currently,the ____ project,a joint effort of experts from industry,academia,and government,is working to standardize UNIX.
A)POSIX
B)BSD
C)ANSI
D)Ubuntu

Accepted Answer

The POSIX project, or Portable Operating System Interface, is a joint effort between experts from industry, academia, and government to standardize UNIX. The goal of this standardization is to provide greater compatibility across different UNIX systems and to allow for the development of portable software that can run on any POSIX-compliant system. The other choices, BSD and Ubuntu, are specific UNIX-based operating systems, and ANSI is a standards organization but not directly involved in the standardization of UNIX.

Question 8

Stephen Bourne at AT&T Bell Labs developed the ____ shell as the first UNIX command processor.
A)Bash
B)Bourne
C)C
D)Korn

Accepted Answer

Stephen Bourne developed the Bourne shell (sh) as the first UNIX command processor. Bash (Bourne-Again Shell) is a later improvement on the Bourne shell, developed by Brian Fox for the GNU Project as a free software replacement for the original Bourne shell. C is a programming language, while Korn shell (ksh) was developed by David Korn at Bell Labs as an improvement on the Bourne shell.

Question 9

The system administrator's prompt is the $ (dollar sign).

Accepted Answer

The system administrator's prompt is typically the # (hash sign), while the $ (dollar sign) is used for regular users in many Unix/Linux systems.

Question 10

The clear command has no options or arguments.

Accepted Answer

The clear command is used to clear the terminal/console screen and does not have any options or arguments.

Question 11

You can switch from one shell to another by typing the shell's name on the command line.

Accepted Answer

You can switch from one shell to another by typing the shell's name on the command line. For example, to switch from the Bash shell to the Zsh shell, you can type "zsh" on the command line and hit enter.

Question 12

In the Linux Bash shell,the ____ key combination moves the cursor to the previous letter.
A)Ctrl+b
B)Alt+d
C)Alt+l
D)Ctrl+a

Accepted Answer

The key combination Ctrl+b moves the cursor one character back, to the left. It is a commonly used shortcut in the Bash shell, especially when editing command lines. Options B, C, and D do not move the cursor to the previous letter.

Question 13

____ is an Internet terminal emulation program.
A)IP
B)Emulab
C)Telnet
D)Terminal

Accepted Answer

Telnet is a protocol used to establish a connection between two computers or devices over the internet. Telnet client software is used to emulate a terminal on the local computer to log in to the remote computer as if one is sitting in front of it.

Question 14

UNIX and Linux are ____ systems,which allow one user to execute more than one program at a time.
A)server-based
B)peer-to-peer
C)multitasking
D)multiuser

Accepted Answer

UNIX and Linux are multitasking systems, which means they can handle multiple tasks or programs simultaneously, allowing one user to execute more than one program at a time. This is different from single-tasking systems, which can only handle one task at a time. The other options, server-based and peer-to-peer, refer to different network architectures, while multiuser refers to the ability of multiple users to access a system or application simultaneously, which is not the focus of this question.

Question 15

Linux uses the freeware ____ shell as its default command interpreter.
A)Bash
B)Bourne
C)C
D)Korn

Accepted Answer

Bash (Bourne-Again SHell) is the default command interpreter for Linux and is widely used because of its extensive features and compatibility with various programming languages. Bourne and Korn shells are also commonly used in Linux but are not the default interpreters. The C shell, while still available in Linux, is not recommended for scripting and is mostly used for interactive shell sessions.

Question 16

In the Linux Bash shell,the ____ key combination deletes the content of the command line from the current cursor position to the end of the command line.
A)Ctrl+b
B)Alt+d
C)Ctrl+k
D)Ctrl+a

Accepted Answer

Ctrl+k is the key combination that deletes the content of the command line from the current cursor position to the end of the command line in the Linux Bash shell. Ctrl+b moves the cursor one character to the left, Alt+d deletes the word to the right of the cursor, and Ctrl+a moves the cursor to the beginning of the command line.

Question 17

To determine information about who is logged in,you can use the ____ command.
A)whatis
B)who
C)whois
D)whoami

Accepted Answer

The "who" command displays a list of users who are currently logged in to the system, along with information such as their username, terminal session, and login time. The other options are not relevant for identifying who is currently logged in to the system.

Question 18

In the Linux Bash shell,the ____ key combination deletes a word or consecutive characters.
A)Ctrl+b
B)Alt+d
C)Alt+l
D)Ctrl+a

Accepted Answer

The Alt+d key combination deletes a word in the Linux Bash shell.

Question 19

The less command scrolls only down,whereas more enables you to scroll down and up.

Accepted Answer

The less command allows you to scroll both up and down through a file, whereas more primarily allows scrolling down, with limited capabilities to scroll up.

Question 20

In the Linux Bash shell,the ____ key combination moves the cursor to the position just before the first character of the next word.
A)Alt+l
B)Alt+d
C)Ctrl+k
D)Ctrl+a

Accepted Answer

The Alt+l key combination in the Linux Bash shell is used to move the cursor to the position just before the first character of the next word.
