• First, check whether your computer’s motherboard is BIOS (Legacy) or UEFI.
• UEFI (Unified Extensible Firmware Interface) is a set of specifications written by the UEFI
• UEFI provides enhanced computer security features and supports most existing BIOS systems
with backward compatibility.
• UEFI supports drive sizes up to 9 zettabytes, whereas BIOS only supports 2.2 terabytes. UEFI
provides a faster boot time.

36. What Is a Linux Command?
• A Linux command is a program or utility that runs on the CLI – a
console that interacts with the system via texts and processes. It’s
similar to the Command Prompt application in Windows.
• Linux commands are executed on Terminal by pressing Enter at the
end of the line. You can run commands to perform various tasks
• For using Linux, you need to use a shell – a program that gives you
access to the operating system’s services.
• Tasks that require multiple steps on the GUI can be done in a matter of
seconds by entering commands into the CLI.

command to know where you are:
• It will print the current folder path
• $ mkdir < directory name > for creating directory
• $ mkdir fruits
• You can create multiple folders with single command
• $ mkdir dogs cars
• You can also create multiple nested folders by adding the -p option:

39. Important commands ..
• $ rmdir <directory name > - for deleting folder/directory
• $ mkdir fruits
• $ rmdir fruits
You can also delete multiple folders at once
• $ mkdir fruits cars
• $ rmdir fruits cars
• To delete folders with files in them, we'll use the more generic rm
command which deletes files and folders using –rf option
• $ rm –rf fruits cars
• Be careful as this command does not ask for confirmation and it will
immediately remove anything you ask it to remove.
• There is no bin when removing files from the command line, and recovering
lost files can be hard.
