$,$

$$sample$.$txt

$)$

$$using a text editor or command line tools such as touch and

echo. Add some random text to this file.

You can use the text editor and save the file with the

$.$

txt extension.

$($

Note: Please choose a sample text such that the below commands can be effectively executed

$.$

$$View the file contents:

Use the cat command to view the contents of the text file you created.

$3$

$.$

$$Review of the text:

Use the grep command to search for a specific word or phrase in a text file. For example, look

for occurrences of the word "Linux."

PART B

NOTE:

$1$

$.$

$$YOU FIRST HAVE TO CREATE FILES IN A DIRECTORY AND SHOW

SCREENSHOT OF CREATED FILE NAMES

$($

YOU CAN CREATE FEW DUMMY.TXT FILES

$)$

$2$

$.$

$$PRODUCE A SCREENSHOT WHEN YOU ARE RUNNING THE SCRIPT IN THE

TERMINAL

$3$

$.$

$$PRODUCE A SCREENSHOT CONSISTING OF RENAMED FILES

Goal: Write a simple shell script to automate a common task.

Steps:

$1$

$.$

$$Create a Shell Script:

Create a text file with a

$.$

sh extension. You can use a text editor of your choice. For example,

you can use the nano text editor to create a new script file named rename

$\_$

files.sh:

bash

Copy code

nano rename

$\_$

files.sh

$2$

$.$

$$Write the Script:

Inside the rename

$\_$

files.sh script, you can write a script that renames all

$.$

txt files in a directory

by adding a prefix to their filenames.

$3$

$.$

$$Make the Script Executable:

Before you can run the script, you need to make it executable. You can do this with the chmod

command:

bash

Copy code

chmod

$+$

x rename

$\_$

files.sh

$4$

$.$

$$Run the Script:

You can now run the script by providing a prefix as an argument. Remember to replace new

$\_$

with the prefix you want to use.

This assignment not only automates a visible task but also helps you learn the basics of

scripting, conditional statements, and loops in Bash
