- Unix MCQ: Q. Which of the following is used with access call for checking the owner’s permissions? a) R_OK b) W_OK c) X_OK d) R_OK, W_OK, X_OKDescription Greetings! Task: Write a program that will ask for the user's name and output their name mixed with a command line argument given as the greeting. Command line args will be formally introduced next week, however, you're encouraged to do some of your own research for this challenge! Python docs: https://docs.python.org/3/library/sys.html#sys.argv PYTHON 1 import sys 2 3 # e.g. $ python main.py foo bar 4 # Arguments would contain: 5 6 sys.argv[0] # => main.py 7 sys.argv[1] % => foo 8 sys.argv[2] # => bar Your program should read the greeting from command line arguments, ask the user for their name, and then output a custom greeting, like so: Example 1 $ python greet.py Yo! What's your name? Jamal Yo! Jamal Example 2 $ python greet.py "G'day" What's your name? Summer G'day Summer Tip: For G'day, be sure to include in double quotes, so Bash treats it as one argument.Course Title : Operating SystemQuestion : How you will create new user using terminal in Ubuntu?

Note: screenshots are mandatory.
- Computer Science Write a script called divisors that prints all the positive divisors of a positive integer specified by the user. The user may specify the integer in one of two ways: As a command-line argument, or When prompted by the script. The script should only print the integers if the user's number is in the range 1 to 100 (inclusive). Your script will first check to see if the user entered a positive integer in the correct range on the command line. If so, the script will print the positive divisors. If not, your script will prompt the user for the number. If the user does not enter a number from 1 to 100 (inclusive) when prompted, your script should only output an error message indicating that the user's number is not in the correct range. Here are four sample runs. Your script should run as follows (what I enter is in bold): oksun8$ divisors Please enter an integer from 1 to 100: 3 1 3 oksun8$ oksun8$ divisors 24 1 2 3 4 6 8 12 24 oksun8$ divisors 2999 Please enter an…Select the best answers.
