6. The kernel is a program that does most of the housekeeping tasks in Linux; it is a layer between computer hardware and software.
a) True
b) False
7. A path that begins at a current directory is called:
a) Complex
b) Relative
c) Absolute
d) Direct
e) Current
8. Output redirection can be defined as sending the output of one command into an input of another command.
a) True
b) False
9. The following command will change the current working directory to the account home directory:
a) Cd account/home
b) Cd /
c) Cd
d) Cd /home
10. Pipe is a feature that allows saving the output of a command in a text file.
a) True
b) False
6. True
7. Relative
8. False
9. Cd ~ or Cd
10. False
6. a) True
To find the answer to this question, you can use your knowledge about the role and function of the kernel in Linux. The kernel is indeed a program that performs various important tasks in Linux, including managing hardware resources and providing services to software applications. It acts as an intermediary between the hardware and software layers of the system.
7. b) Relative
To answer this question, you need to understand the different types of file paths. A relative path is a path that begins at the current working directory. It does not start from the root directory (/) but instead provides a path relative to the current location. For example, if the current working directory is /home/user, a relative path like "documents/file.txt" will refer to /home/user/documents/file.txt.
8. a) True
To answer this question, you should understand the concept of output redirection in command-line interfaces. Output redirection allows you to direct the output of one command to become the input of another command. This can be achieved using symbols like ">" or ">>" to redirect output to a file or using the "|" symbol to pipe the output of one command directly into another command as input.
9. c) Cd
To answer this question, you can refer to the command provided and understand its purpose. The "cd" command is used to change the current working directory. If you execute only "cd" without any arguments, it will take you to the home directory of the current user.
10. b) False
To answer this question, you need to understand the purpose of a pipe in command-line interfaces. A pipe, represented by the "|" symbol, allows you to send the output of one command as input to another command in a sequential manner. It does not save the output of a command in a text file. Instead, it enables the flow of data between commands without intermediate file storage.
6. a) True
7. b) Relative
8. b) False
9. d) Cd /home
10. b) False
