In linux code:
1. Identify command name options in the following command line
$ ls -l / /usr .
$ cat /etc/passwd ../../project
Step by step
Solved in 2 steps
- Commands are passed to the command line of a Linux terminal in the format "\$COMMAND,PARAMETER1,PARAMETER2,...,PARAMETER5\r" i.e., the command begins with the identifying '$' symbol, followed by a command string, then a list of parameters separated by commas. A command can have up to 5 parameters, or no parameters. Parameters can be up to 5 characters in length. Commands end with a carriage return '\r'. Write a function void parse(char *input) that takes in Commands and parses them into a command string and an array of parameters. For the following Commands, print the command string and parameters of each:1. $GETNUM,1\r2. $GETSUM,2,3\r3. $LISTNUMS,10,300,-40\r4. $DONOTHING\r Expected outputs:1.Command string = GETNUMParameter[0]=1 2.Command string = GETSUMParameter[0]=2Parameter[1]=3 3.Command string = LISTNUMSParameter[0]=10Parameter[1]=300Parameter[2]=-40 4.Command string = DONOTHINGThis command has no parameterslinux Write a shell script that takes three parameters (integers) and displays the median number. If the number of parameters is not three, it should display “Just three numbers please”.

Create a simple guessing game (similar to Hangman or Hangaroo). In this game, the user guesses a letter and then attempts to guess the word. 4. Create a Notepad file named words.txt which will store any number of words each written per line. 5. The Java program shall: • randomly select a word from the list saved in words.txt; • display a letter in which some of the letters are replaced by ?; for example, ED??A??ON (for EDUCATION); place the letter in the correct spot (or spots) in the word each time the user guesses a letter correctly; • inform the user if the guessed letter is not in the word; and display a congratulatory message when the entire correct word has been deduced.

This is our module for managingproducts. Create a subfolder in product-manager called lib Create a package.json file. The main property should point to ./lib/products.js. Create a README that explains the purpose of the module. Create a file named products.js in the lib folder. Create a class that represents a product. It should have a name, price, description, and qty property. In products.js create a function called “products” and export that function.This function should return a json array of the fake products. You will need to create an array of fake productobjects in this module to be returned. Copy your new issue-manager module into your node_modules/ folder in your backend project. Normally we would publish ourmodule with npm but then we’d have to manage the path, so we’ll putit directly in our project. When your server.js receives a GET request for products.html, it should call the module and return the products. We’ll also need to use…MCQ: Which class waits for requests to come from the clients.
