Overview of Kali Linux commands:

Kali Linux is an operating system similar to other Linux based operating systems. So basic Kali Linux commands are similar to others.

This Operating system is designed for penetration testing and Ethical hacking. Of course, It has a bunch of ultimate Free Hacking Tools used by black hat hackers.

So basic kali Linux commands are similar to other Linux operating systems but Advance commands are different and awesome.

Commands are made Kali Linux more Attractive and awesome

In this article, I am going to cover how to use Kali Linux commands exactly without knowing anything about the tool.

Many students want to learn Kali Linux free of cost, but due to lack of resources, They can’t. If you are one of them then this article is useful for you.

And they start searching online, and they find lots of articles written by multiple experts, These are available online, but most articles are related on How to install Kali Linux on VirtualBox, how to use tools of Kali Linux.

There is a big difference between the installation of the Kali Linux and using the Kali Linux tools. The gap is how to use Kali Linux commands still exist.

How to finish Kali Linux using Gap?

In this tutorial I will try to remove that gap, so you can complete your journey from installation to using the tools and get involved in penetration testing. In the last article, I have written about Kali Linux hacker so if you want to know more about Kali Linux you can go there and read about it. otherwise, you have another option to know about Kali Linux go on Official website Kali Linux
Before writing this article I think about lots of factor about commands, and find out that:

Kali Linux commands Categories:

  1. System commands
  2. Tool commands
  3. Switches Or Sub-tools

System Commands in Kali Linux:

System commands are basic commands which are used for a system administration, these commands are helpful to manage the Kali Linux operating system.

You can use these commands to manage another Linux Operating system, for example, Ubuntu, Mint, RHEL, etc.

As I have told you in my previous post “Kali Linux system is the combination of Linux OS and Hacking tools”. So all the basic commands are similar to other Linux System.

In this tutorial, I am going to describe basic and advanced Kali Linux commands to manage the operating system.
So good news here, First you will learn basic commands, then you can go for advanced kali Linux commands.

In the sense of meaning, all commands are the same for a normal user, sudo user, and Root user.

A to Z Basic Kali Linux commands in 2020:

Kali Linux commands start from “a”. I know there are many Kali Linux command start from “a”.

Do you want to know? How many commands start from a?

It is very simple to open the terminal and type “a” and press the “tab” tab key from your keyword twice you will see all command start from “a” word.

I find 222 commands start from “a” at the time of writing this article. See in the image below.

Very basic commands can be used by Normal user. The identification of normal user ‘$’ sign, you can see in the following image [email protected]:~$.

1# Arch Command:

You can use the arch command to know computer architecture. Arch command prints things such as “i386, i486, i586, alpha, arm, m68k, mips, sparc, x86_64, etc.

You can use the following Syntax to check your system architecture:

#arch

2# Arp Command:

ARP stands for Address Resolution Protocol, which is used to find the address of a network neighbor for a given IPv4 address.

arp command is used to show the arp table of your Kali Linux system. You can use this command on other Linux systems as well as Windows operating systems.

arp without any option will print the current content of the ARP (MAC/CAM) table.

#arp

#3 arping Command

arping command is similar to ping command but it is working on an Ethernet layer. arping command gives the result of reachability and round-trip time on an IP address in a local network.

#arping -I eth0 -c 5 IPADDRESS

4# Aspell Command:

aspell is a spell checker command in Kali Linux, you can give file name or anything from standard input to check for misspellings.

Syntax: aspell check [options] filename

#aspell -c filename.txt

5# awk command”

awk command is used to manipulate data and generate a report in the scripting language. It allows the user to use a variable, functions both numeric and functions and logical operators.

You can write tiny and effective programs in the form of a statement by using awk utility in Kali Linux.

What can you do with awk?

  1. AWK Operations:
    (a) Scans a file line by line
    (b) Splits each input line into fields
    (c) Compares input line/fields to pattern
    (d) Performs action(s) on matched lines
    awk is Useful For:
    (a) Transform data files
    (b) Produce formatted reports
  2. Programming Constructs:
    (a) Format output lines
    (b) Arithmetic and string operations
    (c) Conditionals and loops

Syntax:

awk options ‘selection _criteria {action }’ input-file > output-file

6# bg command

bg command is used to control shell jobs. It resumes execution of a stoped or suspended process and bg command used to restart a stopped background process

Example
I used ping command followed by technicalustad.com then pressed CTRL +z to stop the service.

Next, I used jobs commands to see available jobs.

Again I used bg command to restart the stoped command “ping technicalustad.com”

7# basename command

You can use basename command to remove base directory information and suffixes from the file names. You can print any file name with any leading directory components removed

Syntax:

#basename NAME [SUFFIX]
or
#basename OPTION NAME

8# Bzip2

Bzip2 is a basic utility for compress and decompress files. It is pre-installed in kali Linux as other commands.

Syntax:

#bzip2 [Options] [filename]

An example:

I used cat command to create a new file name with the filename.txt

Later I used bzip2 command followed by -z (option for compress file) and file name.

Next option -d, I used for decompressing “filename.txt.bz2”

When you use bzip2 command to compress file, The new file will be created with .bz2 extension. You will decompress any file with .bz2 extension by using bzip2 command.

9# cal command:

Cal command is used to display calendar

$cal

10# cat command


This tutorial for hackers, So if you will get access to any computer of the drive then you will 100% find some files. so cat command is used to see, edit matter inside the file. You can create a file and add content inside the file.

How is it possible?

Simple use

$cat > ‘New File’ [Create a new file or overwrite data on the desired file] 

$cat “file name” [See matter inside file]

$ cat >> “filename” [add some data into file] 

Kali linux commands basic use cat

11# cksum command

cksum command stands for checksum is used to calculates a CRC (cyclic redundancy check) and byte count for each input file, and writes it to standard output.

In a simple way, this command is used to check file’s data for being corrupted when transferred one location to another.

Command syntax is simple and straight forward

#cksum filename

12# Clear command

Clear command is used to clear the terminal screen when you are running multiple commands in terminal the terminal screen getting full.

So use the clear command and enjoy a clean screen again.3

#clear

13# cmp Command:

the cmp command is used to compare two files byte by byte. If a difference is found, it reports the byte and line number where the first difference is found.

If no differences are found, by default, cmp returns no output.

Basic syntax of cmp command

#cmp file1.txt file2.txt

14# comm Command

you can use comm command to compare two sorted files line by line. The basic syntax to use this command:

#comm file1.txt file2.txt

15# cp command:

Cp command is used to copy one or more files from one location to another location.

#cp /source/location/path /destination/location/path

If you are copying file from the current working directory then give a file name and source address.

#cp filename /destination/location/path

Use the cp command carefully because it will overwrite files without asking. It means if the destination file name already exists, its data will be erased. you can use -i option to prompt for confirmation.

This is big command and can be used in different ways. here you can read more about https://www.computerhope.com/unix/ucp.htm

16# Crontab Command:

In kali Linux operating systems, The crontab command is used to view or edit the table of commands to be run by cron. The cron table is the list of tasks scheduled to run at regular time intervals on the Linux system.

The daemon which reads the crontab and executes the commands at the right time is called cron.

Crontab command examples

#crontab -e
Edit your crontab.

#crontab -l
Display (“list”) the jobs of your crontab.

#crontab -r
Remove your crontab.

#crontab -u technicalustad -e
Edit crontab for user technicalustad.

16# cut Command:

cut command is used to cut parts of lines from specified files or piped data and print the result to standard output. It can be used to cut parts of a line by delimiter, byte position, and character

The basic syntax for the cut command is as follows:

[email protected]:~#

the date can be changed by running the following code

$ date –set=’20 September 2019 13:09′

but the normal user can’t change system time, Then you are thinking about “how to change system time” Of-course I will teach you in this article, dont worry about it.

Some examples of date command:

$ date -d now
$ date -d today
$ date -d yesterday
$ date -d tomorrow
$ date -d sunday
$ date -d last-sunday

[–expression=scriptexpression] [-f scriptfile] [–file=scriptfile]

18# Dd command

dd stands for data duplicator, which is mainly used to copy and convert data. but this tool can be used for:

  • Backing up and restoring an entire hard drive or a partition.
  • Creating virtual filesystem and backup images of CD or DVDs called ISO files
  • Copy regions of raw device files like backing up MBR (master boot record).
  • Converting data formats like ASCII to EBCDIC.
  • Converting lowercase to uppercase and vice versa.

dd command is not basic command so you must be superuser to execute it.

Syntax of dd command is

dd if= of= [Options]

19# df command

28# pwd command:


pwd command is used for print working directory. It means “On what location you are“. here location meaning is directory and sub-directory.

The parent directory is “/” called root directory.

Don’t be confused with /root directory, this root directory “/root” is home directory for root user.

[email protected]:~#pwd
/root
[email protected]:~#

30# ls command:


ls command is used to see files and directory inside a directory. using ‘ls’ without any location will list the files and folders inside the current directory.

If you want to look up inside another directory, you will have to specify location.

$ls

$ls /var

$ls /home/username

31# cd command:


the cd command is a very useful command and plays a very important role for Linux user. This command is used for changing directory. And the basic syntax will be as below:

cd /desired/location

If you use blank ‘cd’ without location then you will move in the user’s home directory. so see the power of cd commands and enjoy!

$cd

$cd ..

$cd /desired/location ($cd /home/vijay)

32# mkdir command:


Do you know about the directory? It is a term used for the folder. You can say windows folder is a directory in Linux It is very easy to create a folder in Windows” but not in Linux. T

The graphical interface is really awesome, but the command interface is not less. The command-line interface is the fastest way to operate a Linux based Operating System. Linux users love it.

mkdir command is used to create a directory. if want to create a directory within the current directory, just use mkdir ‘directory name’.

if you want to create a directory in the desired location then

$mkdir /desired/location/directory name.

$mkdir lab

[email protected]:~#mkdir lab
[email protected]:~#mkdir lab/lab1
[email protected]:~#

$mkdir /home/vijay/lab1

33# mv command:


If you don’t like files and folders on the current location and want to move to another location, then mv command is useful for you. mv command work as a cut and paste in windows.

$mv /Source_location /destination/location

mv source location if the file or directory does not exist in current location if the file/folders within current location then us mv file/folder name [space] destination location {destination location = where you want to move}

mv command is also used for rename the file and folder

$mv ‘old filename’ ‘new filename’

34# rm command:


rm command is used to remove files and folders. In other words this command for deleting files and folders.

#44: Find Command

The find command is used for search files in Linux. Searching any files and folders in Windows is easy but in Linux.

To find a file by name, size, type, etc in the graphical interface is quite easy, And it is not really so easy in CLI (Command Line Interface)

Find is a command-line utility that allows you to search for files and directories in a directory hierarchy based on user-given expression and applies user-specified action on each matched file

Usage: find [-H] [-L] [-P] [-Olevel] [-D debugopts] [path…] [expression]

[email protected]:~#find -L /etc -name passwd
/etc/pam.d/passwd

the apt-get command is a most popular command for Debian based operating systems including Kali Linux.

All the available options are below with apt-get command.

#46 dpkg command

dpkg command is used to Install deb File in Kali Linux. You can remove packages by using dpkg command as well.

Kali Linux is a Debian based operating system so you can install .deb files only.

For example: you can install Nessus on Kali Linux by using dpkg because the Nessus files do not exist in the repository.

You can run the following command to install packages on Kali Linux by using dpkg command

#dpkg -i package_name

dpkg –i /{Download_Location}/Nessus-{Version}.deb

#50 passwd command To change password

Username and password are the basic security of the Kali Linux operating system. You are working on cybersecurity / ethical hacking.

You must keep in mind all security points, and managing password is one of them.

passwd command is used to change the password of a normal user / sudo user/ root user.

Basic example: You are login with root user and want to change current user password then simple syntax as follows:

#passwd

[email protected]:~#passwd
New password: 
Retype new password: 
passwd: password updated successfully
[email protected]:~#

As you hit enter, you get the screen to enter a new password twice. You will not see anything on the screen at the time of entering a password. Don’t worry at all.

Give a new password and hit enter, again enter the same password and hit enter. Your password for the current user will be updated.

More Details: How to change password in Linux

#51 usermod command

usermod command is used to modify a user in a group.
