log files, and

other text$-$based data in a Linux environment.

Please provide a screenshot as proof of work for every instruction executed.

Log in to Ubuntu

instructions:

$1.$ Create a text file:

Create a text file $($e$.$g$.,$ 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$)$

$2.$ 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."

grep $-$i $$text$\_$to$\_$search$$ sample.txt

$4.$ Read the alphabet:

Use the wc command to count the number of words and characters in a text file.

$5.$ Complete the text:

Use the sort command to sort the text in a file alphabetically.

$6.$ Create a new file with the following text:

Use the $>$ or $>>$ operator to redirect the sorted output to another file $($e$.$g$.,$ sorted$\_$sample.txt$).$

$7.$ Replace text:

Use the sed command to replace a specific word or phrase in the root text file $($e$.$g$.,$ "Ubuntu"

instead of "Linux"$).$

$8.$ Add text to the original file:

Use the $>>$ operator to add additional information to the original file $($e$.$g$.,$ add a few lines$).$

$9.$ Extract specific Lines:

Use the head and tail commands to remove the first and last lines of the text file.

$10.$ Remove specific Lines:

Use the sed or grep $-$v command to extract specific lines containing a specific word from a text

file.

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
