Introduction

Kali Linux Commands is an advanced penetration testing distribution by offensive security. It is available in 32 bit, 64 bit and ARM flavors. Its features allow users to create custom complex images with ease. Kali Linux terminals offer certifications such as OSCP, OSWE, OSEP, OSWP, OSEE, and KLCP. The testing tools of Kali Linux commands can be categorized into information gathering, web applications, vulnerability assessment, password attacks, exploitation tools, sniffing and spoofing, maintaining access, system services, and reporting tools. 

Kali Linux comes with tools that could be used for wireless attacks, reverse engineering, forensics, stress testing, and hardware hacking. it can be installed using a USB disk, hard disk, and Live DVD. Network services are HTTP, MySQL, and SSH. These are extremely helpful in operating the Kali Linux commands. 

Kali Linux operates on certain android devices. Its predecessor is BackTrack that got carried over to Kali via live boot. The system is easy to use once the user get command over it.

H) Cat Command

This enables the user to read files, link them together, exchange their contents, and one of the most commonly used kali Linux commands. 

I) Cp Command

This is used for basic copying text or similar purpose. It can copy one or more than one file to certain location of your choice. This also helps in moving directories. 

J) Mv Command

This is used to move files between directories. It is extremely convenient when dealing with complicated files. 

K) Rm Command

This command removed highlighted texts and is a very basic yet essential command. It is used to remove symbolic links and objects from files. It also eliminates multiple references from objects. References are files with two or three names. 

L) Uname Command

This is an easy command helping to retrieve the user name of the version. Adding hyphen to uname would provide further details of the version. For instance – It will mention the machine, release date, note name etc. 

M) Uptime Command

It is used to find out the longevity of the system is active (running). This command returns set of values that involve, the current time, and the amount of time system is in running state, number of users currently logged into, and the load time for the past 2, 6 & 16 minutes respectively. It basically provides the duration of time. 

N) Less Command

This command presents all the activities that are going on with a certain file but only partially loads it. It also saves some RAM.

O) More Command

It helps in viewing contents of a file in a convenient manner providing a bird’s eye view of the contents of a file. It saves the user’s time in scrolling through the whole thing. 

P) Sort Command

It sorts out the information and arranges contents in an orderly manner. Reverse switch could also be used to organize the contents in reverse order.

Q) Vi Command

This command provides multiple options such as inserting at cursor, writing after the cursor, terminating the insert mode, opening a new line, undoing a certain action and deleting lines or images. This tool can be combined with others to perform more actions. 

R) Free Command

This is used to display the memory usage of the current system. This is particularly useful when you wish to download a new software and need to know the exact memory in your system. As free displays the details of the memory related to your system , its syntax doesn’t need any arguments to be passed but only options which you can use according to your wish. 

S) Chmod Command

This command is used to to change the mode restricting user access to a certain file as per the instructions provided. It is a popular command on this operating system.

There are modified ways of using this command. For instance – to view the last 25 commands, history | 25 can be used, to view the last 10 commands, history | less could be used. 

Conclusion

Kali Linux uses the Live DVD Linux distribution system that has been specially developed to help you in the penetration testing process. The top 20 Linux commands are the most widely used commands on the system.

Kali Linux is an operating system that could be installed on the user’s PC. It is an alternative to windows 8, windows 10, windows 7 and MAC. It can be installed for free on your system. This operating system is used for hacking purpose and digital attacks. Kali Linux operating system prevents users from creating long programming to do penetration testing, security checking or website hacking. Its biggest advantage is the availability of readymade tools. Many big organisations use this operating system to teach hacking.
