Trivia Quiz On Linux Basics For Beginners!

The correct answer is "mkdir". This command is used to create a new directory in a file system.

The correct answer is "ls". The "ls" command is used in Unix-like operating systems to list files and directories in the current directory. It displays the names of all files and directories in a formatted manner, allowing users to easily view the contents of the current directory.

The "who" command is used to display the users who are currently logged in to the system. It provides information such as the username, terminal, login time, and remote host. By using the "who" command, the system administrator or user can see the list of active users and their activities on the system.

The touch command is used to create an empty file.

The command "cd" is used to access a specific directory. By typing "cd" followed by the directory name, the user can navigate to that directory and access its contents. This command is commonly used in command line interfaces to move between different directories within a file system.

The command "clear" is used to clear up the command prompt window.

SSH (Secure Shell) is the best tool to use for logging in remotely to an Apache server. It provides a secure and encrypted connection, ensuring that the data transmitted between the client and the server is protected from unauthorized access. On the other hand, tools like rsh, rlogin, telnet, and login do not provide the same level of security and encryption as SSH, making them less suitable for remote logins.

The correct answer is "insert" because "insert" is a valid mode of operation in the vi text editor. In insert mode, the user can directly type and insert text into the document. This mode allows for editing and adding content to the file.

The "man" command is used to display the manual pages for a specific command on the shell. It provides a detailed explanation of the command, including its usage, options, and examples. By using the "man" command followed by the desired command name, users can access comprehensive information about the command and its functionality.

To delete a file in Linux without a confirmation message, use the "rm -f" command. The "rm" command is used to remove files and directories, and the "-f" option, which stands for "force," instructs the command to delete the file without prompting for confirmation. Be careful when using this command to avoid accidentally deleting important files.

To create an installation boot floppy, the utility that should be used is fdisk. Fdisk is a command-line utility used for partitioning hard drives on Linux systems. In this case, it would be used to create a bootable floppy disk that can be used to boot the PC and initiate the Linux installation process.

The correct answer is "chmod 700 fifteen". The command "chmod" is used to change the permissions of a file. The number "700" represents the permissions for the file, where the first digit (7) represents the permissions for the owner (root), the second digit (0) represents the permissions for the group, and the third digit (0) represents the permissions for other users. In this case, "7" gives the owner (root) read, write, and execute permissions, while "0" denies all permissions to the group and other users. Therefore, using "chmod 700 fifteen" will change the permissions of the file "fifteen" as desired.

When installing a software package from source code, the file will typically have the .src extension. This extension indicates that the file contains the source code of the software, which is the original code written by the developers. By compiling this source code, the software can be built and installed on the system. Other extensions like .exe, .tgz, .bff, and .bin are commonly used for executable or compressed files, but when installing from source code, the .src extension is the most appropriate.

The most secure way to give a normal user the ability to run a shell script that must be run as root is to set the SUID (Set User ID) bit on the script. This allows the script to be executed with the privileges of the file's owner (in this case, root), even when it is run by a normal user.

Runlevel 6 is the correct answer because it is the runlevel that initiates a system reboot. In Linux, runlevels are specific operating modes that determine which services and processes are running. Runlevel 6 is typically used for system reboot, as it stops all processes and services, unmounts filesystems, and then restarts the system. Runlevels 0, 1, 2, and 4 have different purposes, such as shutdown, single-user mode, multi-user mode, or custom configurations, but they do not initiate a system reboot like runlevel 6 does.

The command "chgrp" can be used to change the group owner of a file. This command allows the user to modify the group ownership of a file or directory. On the other hand, "chmod" is used to change the permissions of a file or directory, not the group owner.
