Important points on Kali Linux

• To check how much memory is being used on Linux, we can use a command called “Free“.
• “top” command Show the utilization of Linux and currently active processes.
• “Grep” command helps find words or phrases in a file or text.
• Penetration testing is when a security expert tries to find and use weaknesses in a computer system. This helps find any gaps in the system’s protection that a bad person could use.
• BASH (Bourne Again Shell) is a program that understands and follows commands. It is like a special language that helps you communicate with your computer. It was made to be an easier and more useful version of another program called Bourne Shell. BASH has some extra features like editing commands and is the default shell for most Linux computers. It is like a process that can be run in a terminal window and can understand and execute commands written in its language.
• Sniffing is when someone listens to other people talking or steals information from a network. Spoofing is when someone pretends to be someone else. In this case, the attacker sends fake messages over the network to trick the victim.

Kali Linux (formerly known as Backtrack Linux) is an open-source Debian-derived Linux distribution designed primarily for digital forensics and penetration testing. It serves as a specialized operating system used by cybersecurity professionals and ethical hackers to assess the security of computer systems. Kali Linux comes preloaded with a variety of tools that can be employed for tasks such as identifying vulnerabilities and analyzing computer data.

A keyboard shortcut (or hotkey) is a quick way to execute specific functions within a computer program or operating system by pressing a combination of keys simultaneously.

Kali Linux users often engage in extensive typing tasks. They gather information before attempting to penetrate a system and employ testing tools for various security assessments. This typically involves frequent interaction with command-line terminals. To enhance productivity in Kali Linux and save time, you can learn special keyboard shortcuts that facilitate common actions. This guide provides a list of these shortcuts and instructions on creating custom ones.

There are two main categories of Shortcut Keys in Kali Linux:

• Predefined Shortcut Keys: These are keyboard shortcuts that come predefined with Kali Linux.
• Users Define Shortcut Keys: Users can create their own custom keyboard shortcuts for specific functions.

In this guide, we will assume the use of the Xfce desktop environment, which is the default in Kali Linux. Other desktop environments like GNOME and KDE may have different key combinations for similar actions.
