In order to add portability, one of the strongest aspects, they redesigned the entire operating system in C language in 1973.

UNIX MCQ Question 4

Which of the following is not a feature of Unix?

  1. multiuser
  2. easy to use
  3. multitasking
  4. portability

Answer: B. easy to use

Solution

A user can execute numerous tasks simultaneously since UNIX is a multitasking operating system. The fact that it enables collaboration among multiple users on a single operating system makes it a multiuser system. However, a significant drawback of UNIX is that its command-line richness necessitates a particular kind of dedication to comprehend the topic. In other words, the user must be fully aware of the commands and how they work.

UNIX MCQ Question 5

Which Unix command is used for changing the current directory?

  1. pwd
  2. rm
  3. cd
  4. cp

Answer: D. cd

Solution

For navigating the file system, use the cd (change directory) command. Usually, a parameter is used to run the cd command. The directory supplied as an argument replaces the current directory as soon as it is invoked. To copy files, use the cp command, and to delete them, use the rm command.

As an illustration, suppose that our current directory is /bin/user06 and that we want to change it to a directory called dir one that is located inside the user06 directory. Enter the following command:

$ cd dir_one

$pwd

/bin/user06/dir_one
