How to compress files into rar?

Due to licensing issues, an Ubuntu installation does not include packages for RAR files natively. 
        
        Open a terminal and install a rar package:
        
        sudo apt install rar
        
        Here is a basic syntax to compress files:
        
        rar [command] [ArchiveName] [file]
        
        For example:
        
        sudo rar a rartest file1.txt file2.txt
        
        Sample output:
        
        To add a password to your archive, just add -p option to the end of your command and you will be prompted to enter a password:
        
        sudo rar a rartest file1.txt file2.txt -p
        
        Decompress RAR files on Ubuntu

We have to install a package called unrar from the official Ubuntu repositories.
        
        Run the following in your terminal:
        
        sudo apt install unrar

Follow this syntax to decompress files in Ubuntu:
        
        unrar x [rar-file]
        
        Sample output:
        
        
        If the file is password-protected, you will be prompted immediately.
        
        Congratulations! You have learned how to compress and decompress files from a terminal in your Ubuntu Shell.
