All Kali Linux Commands (A-Z) – Kali Commands PDF


Kali Linux Commands are very useful if you are using the terminal in Linux Kali distribution. Kali Commands PDF is a very handy way to use Linux Kali Commands.

Kali Linux – two words combined together. This suggests a twofold activity. One is digital forensics and the other is penetration testing. It encompasses other activities such as Security Auditing and research, Computer Forensics and Reverse Engineering. The whole process is funded by Offensive Security Limited and is specifically designed to meet the security needs and audits. To describe in layman terms, Kali Linux is an operating system that was initially known as BackTrack. Though it is similar to other Linux based systems, it has a unique feature that is entirely different. It has free hacking tools that are most needed or used by black hat hackers. The security tools used are Armitage, Aircrack-ng, and Burp Suite and so on. In addition, the changes or updates made in Kali Linux are basically to fulfill specific needs such as:

  1. Single root user: Because of security concerns, many penetration tests need extra privileges and so single root user is considered a privilege.
  2. Disable network services: Kali Linux has unique system hooks that disable network services including Bluetooth.
  3. Minimal repositories: Since the integrity of the system has to be maintained at all cost, the upstream software sources set is kept at a minimum.

Linux Kali Commands

The best and easiest way to use Kali Linux is by using commands. There are many commands to remember so many new users might find it difficult to remember or learn them. One good point is that since the system is similar to other Linux operating systems, the basic commands are quite similar as well. The advanced commands are of course top-notch. This article will cover some of the basic and advanced commands. The commands can be divided into two main categories.

System Commands

This is the name itself denotes are used for system administration and are useful for managing the Kali Linux operating system. The commands are similar to the ones used in Mint, RHEL, and Ubuntu.

Some of them which make it on the list of the SYSTEM COMMANDS are :

  • history command: This gives details about the running commands used recently. The Code is $history
  • Free command: This shows the total, free and the swap memory information that is the memory used till and now and how much is still available. The code is $free
  • sort command: as the name itself signifies the lines of text files can be sorted in ascending order or descending order. The code for ascending order is $sort filename.txt and for descending order it is $sort –r filename.txt

Then there is the System Advanced Commands in Kali Linux Commands:

  • Find command: In order to find a file by name, size is very difficult in Linux. So this command is useful as it helps the user to search for files based on user given expression and user-specified action.
  • The unzip command: Most of the big files downloaded are in zip format. This command will help in unzipping or extracting the files. The basic syntax is #unzip file name.zip
  • The SCP command: This is used for copying files from one device to another device. The noteworthy feature is that is copies files over ssh protocol. Hackers use this command to compromise the system and transfer files.
  • Other commands which are available are the Cron command which is a daemon for executing scheduled commands. The fgrep command searches for files that meet specific criteria. And last of all, of course, is the help command which displays all the built-in commands.

Tool or basic commands

Basic commands are very simple and can be tried out by new users. To spell out a few commands, ls stands for list directory, Nmap means network mapper (for scanning open ports, OS detection), lsblk means list block devices. Noteworthy commands are apt-get. This updates a Debian machine and is used for installing Debian packages and programs. The Sudo command is used for executing a command as root user and the Chroot command allows for a command to run with a different root directory.

There are other simple commands which are enumerated below:

  • date command: This is used for checking the current time and date. It involves using the # hashtag and $ sign. This date can be changed by using the following code: $ date-set=’new date’
  • cal command: This is for displaying the calendar. The code is $cal
  • whoami command: This is used to find out the user name by which you have logged into. The code is $whoami
  • pwd command: This is to know on what location you are working on that is the directory and subdirectory details.
  • is command: this is used for knowing the files and folders inside a directory. The code is $Is
  • cd command: this is for changing the directory. The code is $cd
  • mkdir command: this is used for creating a directory. The code is $mkdir. However, if a directory is needed in a particular location, then it has to be specified in the code. For instance, the code will then have to be $mkdir/desired location/directoryname
  • cp command: This command is used to copy files and folders. It is actually a big command.

So with the use of a few simple commands, websites and wireless networks can be hacked. Not only that tasks can be automated and software programs can be installed. In addition, the creation of additional user accounts, optimization of terminal interactions, the configuration of software, etc. can be done with just a few of these commands.

Final Verdict

With this article, it is hoped that most of the useful commands are covered and so Kali Linux can be used to the maximum. There is no fixed list of commands. They are based on the user needs and therefore have not been numbered in this article. Some users might prefer or use only certain commands whereas others might prefer some other commands. So a right mix of different commands have been included in this article and so hope that you find them useful.
