3. Create a new user named "guest" using the adduser command.
4. Change the ownership of the "LinuxAssignment" directory and its contents to the "guest" user.
5. Switch to the "guest" user using the su command.
6. Attempt to access and modify the contents of sample.txt. Observe the results.

Task 5: Searching and Archiving

1. Search for all files with the ".txt" extension in the "LinuxAssignment" directory.
2. Archive the entire "LinuxAssignment" directory into a compressed file named "LinuxAssignment.tar.gz."
