Task $2$

Your recently acquired Linux, File permission, Bash Shell skills have given you the

confidence $.$ This is your opportunity to take a leadership role as you will be the top

brain in this operation.

Instructions

Use the instructions below to plan and implement your project. It is recommended that

you perform the tasks in the order given below.

How can we get the number of lines or number of words in a file?

The easiest way to count the number of lines, words, and characters in text file is to use

the Linux command $$wc$$ in terminal.

To count the number of lines, use $$wc$$ with $$l$$ as

wc $$l yourTextFile

To count the number of words, use $$wc$$ with $$w$$ option as

wc $$w yourTextFile

Write a shell script to read the number of lines and print there count in file. $($You need

to create any sample file and read it into the program$)$

Create new text file and read and show the count using shell script. Provide appropriate

file permission while running the shell script.

Task $3$:

Develop the classic game "Hangman". First It will ask to enter the username, after

entering the name, Game will start. You need to create the game such that user need to

guess the character from the word.

The word to guess is represented by a row of dashes. If the player guesses a letter

which exists in the word, the script writes it in all its correct positions. The player has

$10$ turns to guess the word. You can easily customize the game by changing the

variables.

Example: The variable value used in game is $$Employee$$ then user need to guess the

character from number, if the character matches with in the word then It will added as

a dashes.

Following output, it should display:

What is your name? Usama

Hello, Usama Time to play hangman!
