Practicals

In this practical, you’ll learn how to dual boot Linux alongside Windows.

1. Create a Folder named after TYIT.

2. Create a blank file named directory.txt

3. Now list the directories in the root directory and store the output in the directory.txt file

4. Now search for words in the directory.txt file which contains the alphabet e

5. Move the file named directory.txt from TYIT to a directory named FTYIT. Additionally, rename the file to Fourth.txt.

6. Finally remove the folder named TYIT.

7. List the permissions for Fourth.txt

8. Also list the hidden files in your home directory

9. Make a hidden file named secrets.txt

1. Start the gedit app in the background from the terminal.

2. Bring it to the foreground and suspend it.

3. Reactive it and then terminate it.

4. Start Firefox. List it’s process id. Terminate it using the kill command.

5. Make a file named A.txt in the home directory. This file can contain some text in it. Make a symbolic link on the desktop.Then make sure to check if a link is created. Try displaying the contents of the file by using the symbolic link.

6. Also list the inode numbers of the linked file and the original file.

7. Make a file named B.txt in the home directory. This file can contain some text in it. Make a hard link on the desktop. Then list out the number of links of that file. Also list the inode numbers of the linked file and the original file.

8. Install the following programs using apt:

   • Python Pip

   • Python Virtual Environments

   • ffmpeg

   • vscode

   • sqlite

   • chrome

Make sure to log the installations of the programs to a file named installer_log.txt

Write a basic shell script that:

• Prints the current time.

• Allows the user to create a folder within a specified directory.

• Allows the user to generate multiple folders in a particular directory specified by the user.

• Checks whether a file or folder exists based on the name provided by the user.

• Allows the user to install an application easily.

You are given a file: words.txt

It contains unstructured data. Using basic linux commands (grep, sort, wc, uniq)  do the following analysis on the file

• Find out the number of words in the file excluding the numbers and punctation marks.

• List all the numbers in the ascending order.

• Find the top five words which are repeated in this file. 

• List all the single digit numbers from this document without repetitions

• Separate the numbers and the words from the file. Remove the repetitions and store the numbers  in a file called num.txt and the words in a file called words.txt.

1. Create three users with home directories: Bob, Sally and Larry

2. Set passwords for these users.

3. Create a group named coders and add these users to that group.

4. Create a file named prac6.txt

5. Handover the ownership of that file to the user named Larry and to the group named coders.

6. Set a sticky bit for the file named prac6.txt

7. Create a folder named prac6

8. By using an access control list, give Sally and Larry access to the folder named prac5

9. Act as Sally and create a file within that folder.

10. Act as Bob and create a file within that folder.

Now try to delete one 80gb disk to see if the system will boot.
