This document provides an overview of basic commands in Kali Linux for new users. It begins by explaining that Kali Linux commands are similar to other Linux systems but with additional penetration testing and hacking tools. The document then covers over 30 basic commands in Kali Linux, providing the syntax and use case for each command. It aims to
help new users learn the basic commands needed to manage the operating system and begin using some of the security tools.

BACKGROUND
: A shell provides a command-line interface for users. It interprets user commands and executes them. Some shells provide simple scripting terms, such as
if
or
while
, and allow users to make a program that facilitates their computing environment. Under the hood, a shell is just another user program as you know from Minor2 assignment. The file
/bin/bash
is an executable program file for the bash shell. The only thing special about your login shell is that it is listed in your login record so that /bin/login (i.e., the program that prompts you for your password) knows what program to start when you log in. If you run "cat /etc/passwd", you will see the login records of the machine.
PROGRAM DESCRIPTION
GROUP COLLABORATIVE PORTION
: In this assignment, you will implement the shell “engine” as the group component, where all members are responsible for the following functionality.
A Command-Line Interpreter, or Shell
Your shell should read the line from standard input (i.e., interactive mode) or a file (i.e., batch mode), parse the line with command and arguments, execute the command with arguments, and then prompt for more input (i.e., the shell prompt) when it has finished. This is what Minor 2 program should do with addition of batch processing which means just reading a batch line by line and calling the same interpretation logic.
Batch Mode
In batch mode, your shell is started by specifying a batch file on its command line. The batch file contains the list of commands that should be executed. In batch mode, you should not display a prompt, but you should echo each line you read from the batch file back to the user before executing it. After a batch is finished the shell will exit.
Interactive Mode
No parameters specified on command line when the shell is started. In this mode, you will display a prompt (any string of your choice) and the user of the shell will type in a command at the prompt.
You will need to use the fork() and exec() family of system calls. You may not use the system() system call as it simply invokes the system’s /bin/bash shell to do all of the work. You may assume that arguments are separated by whitespace. You do not have to deal with special characters such as ', ", \, etc. You may assume that the command-line a user types is no longer than 512 bytes (including the '\n'), but you should not assume that there is any restriction on the number of arguments to a given command.
INDIVIDUAL PORTIONS
Build-in Commands:
Every shell needs to support a number of built-in commands, which are functions in the shell itself, not external programs. Shells directly make system calls to execute built-in commands, instead of forking a child process to handle them.
In this assignment, each member of the group will implement one of the following section and commit in GitLab the code that supports those commands:
Add a new built-in
alias
command that allows you to define a shortcut for commands by essenti.
OverviewIn this assignment you will write your own shell i.docxalfred4lewis58146
Overview
In this assignment you will write your own shell in C. The shell will run command line
instructions and return the results similar to other shells you have used, but without many
of their fancier features.
In this assignment you will write your own shell, called smallsh. This will work like the
bash shell you are used to using, prompting for a command line and running commands,
but it will not have many of the special features of the bash shell.
Your shell will allow for the redirection of standard input and standard output and it will
support both foreground and background processes.
Your shell will support three built in commands: exit, cd, and status. It will also support
comments, which are lines beginning with the # character.
Specifications
All execution, compiling, and testing of this program should be done from the bash
prompt on the eos-class.engr.oregonstate.edu server.
Use the colon : symbol as a prompt for each command line. Be sure you flush out the
prompt each time you print it, this makes the test script look nicer.
The general syntax of a command line is:
command [arg1 arg2 ...] [< input_file] [> output_file] [&]
…where items in square brackets are optional. You can assume that a command is made
up of words separated by spaces. The special symbols <, >, and & are recognized, but
they must be surrounded by spaces like other words. If the command is to be executed in
the background, the last word must be &. If standard input or output is to be redirected,
the > or < words followed by a filename word must appear after all the arguments. Input
redirection can appear before or after output redirection.
Your shell does not need to support any quoting; so arguments with spaces inside them
are not possible.
Your shell should support command lines with a maximum length of 2048 characters, and
a maximum of 512 arguments. You do not need to do any error checking on the syntax of
the command line.
Command Execution
You will use fork, exec, and waitpid to execute commands. The shell will wait for
completion of foreground commands (commands without the &) before prompting for the
next command. The shell will not wait for background commands to complete.
Background commands should have their standard input redirected from /dev/null if the
user did not specify some other file to take standard input from. What happens to
background commands that read from standard input if you forget this?
Your shell should use the PATH variable to look for commands, and it should allow shell
scripts to be executed (see below for the testing script, for example). The right version
of the exec function will do this for you automatically. If a command fails because the
shell could not find the command to run, then the shell will print an error message and set
the exit status to 1.
After the fork but before the exec you must do any input/output redirection. A redirected
input file should be opened for reading.

2. Kali linux basic commands with examples pdf
the easiest way to oare kali linux from commands, but you should know that there are thousands of kali linux commands. and the biggest problem for the new user to learn these commands. kali linux is an operating system similar to other operating systems based on linux. then the basic kali linux commands are similar to others. This operating
system is designed for penetration test and ethical hacking. of course, it has a lot of latest 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 fantastic. commands are made kali linux more attractive and impressive in this article, I’m going to
cover how to use the kali linux commands exactly without knowing anything about the tool. Many students want to learn kali linux for free, but due to lack of resources, they can not. if you are one of them then this article is useful for you. and start looking online, and find a lot of articles written by multiple experts, these are available online, but most
items are related on how to install kali linux on virtualbox, how to use the tools of kali linux. there is a great difference between the installation of the kali linux and the use of the kali linux tools. the gap is how to use the kali linux commands still exist. How to finish kali linux oando gap? in this tutorial I will try to remove that gap, so you can complete
your journey from the installation to use the tools and participate in penetration tests. in the last article, I wrote about kali linux hackers 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 to the official website kali linuxbefore writing this article I think about
a lot of factor on the commands, and find out that: kali commandscategories: system commands of switch system commands or sub-tools in kali linux: system commands are basic commands that are used for a system systemThese commands are useful for managing the Kali Linux operating system. You can use these commands to manage another
Linux operating system, such as Ubuntu, Mint, RHEL, etc. As I told you in my previous post “Kali Linux system is the combination of Linux OS and Hacking tools”. So all basic commands are similar to other Linux System. In this tutorial, I’m about to describe the basic and advanced Kali Linux commands to manage the operating system. That's good
news here. First you learn basic commands, then you can go for advanced Linux kali 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: The Kali Linux commands start from “a”. I know there are many Kali Linux commands that start from “to”. You
want to know? How many commands do you start from one? It is very simple to open the terminal and type “to” and press the “tab” tab from the keyword twice you will see that all commands start from “to” word. I find 222 commands start from “a” when writing this article. See in the image below. Very basic commands can be used by the normal
user. The identification of the user's normal sign '$', you can see in the following image [email protected]: ~$.1# Arch Command: You can use the arc command to know the architecture of your computer. The command of the arc prints things like “i386, i486, i586, alpha, arm, m68k, mips, sparc, x86_64, etc. You can use the following Syntax to control
system architecture:#arch2# Arp Command:ARP stands for address resolution protocol, which is used to find the address of a network neighbor for a certain IPv4 address. Arp command is used to show the arp table of the Kali Linux system. You can use this command on other Linux systems as well as on Windows.arp without any optionthe current
content of the ARP table (MAC/CAM). #arp#3 arping # Commandarping is similar to ping command, but it works on an Ethernet layer. ardent ardentgives the result of a reach and an hour of return to an IP address in a local network. #arping -I eth0 -c 5 IPADDRESS4# Aspell Command:aspell is a spell checker command in Kali Linux, you can give
the file name or anything from the standard input to control misspelling. Syntax: aspell check [options] file name #aspell -c. txt5# awk command”awk command is used to manipulate data and generate a report in the scripting language. Allows the user to use a variable, both numerical functions and logical functions and operators. You can write small
and effective programs in the form of a statement using the awk utility in Kali Linux. What can you do with Awk? AWK Operations: (a) Scan a line of rows per line (b) Split each input line in fields (c) Compare the line of input/model fields (d) Runs actions(s) on corresponding lines awk is useful for: (a) Transforms data files (b) Produce formatted
reports Programming builds: (a) Format output lines (b) Aritmetics and string operations (c) Syntax conditions and loops:awk options ‘selection _criteria {action }’ input-file > output-file command 6# bg commandbg is used to control shell jobs. Resumption of execution of a interrupted or suspended process and bg command used to restart a
interrupted background process Example I used the ping command followed by technicianustad.com then pressed CTRL +z to stop the service. Later, I used the work commands to see the jobs available. Once again I used the bg command to restart the stoped command “ping technicianustad.com”7# basename command You can use the basename
command to remove the basic directory information and suffix from file names. You can print any file name with any main directory component removedSyntax: #basename NAME [SUFFIX] or #basename OPTION NAME8#Bzip2 is a basic utility for compression and decompressing files. It is preinstalled in Linux kali as other commands. ♪ [Options]
[filename] An example: I used the cat command to create a new file name with the file name. txtLater I used the bzip2 bzip2 commandfrom -z (option for compressed file) and file name. Next option -d, I used to decompress "filename.txt.bz2" When using the bzip2 command to compress the file, The new file will be created with .bz2 extension.
Decompress any .bz2 file extension using the bzip2 command. 9# command cal: The Cal command is used to display the calendar[email protected]:~#cal October 2019 Su Mo Tu We Th Fr Sa 1 2 3 4 5 6 7 8 9 11 13 15 16 18 19 20 21 22 25 27 29 30 31 [email protected]:~# 10# command of the cat This tutorial for hackers, So, if you get access to any
computer drive, then you will find 100% some files. then the cat command is used to see, edit the matter within the file. You can create a file and add content within the file. How is that possible? Simple use $cat > 'New file' [Create a new file or overwrite the data on the desired file] $cat "file name" [See the subject within the file]$ cat > "file name"
[add some data in the file] 11# cksum command is for checksum is used to calculate a CRC (cyclic redundancy control) and byte count for each file. Simply, this command is used to control the file data to be corrupted when transferring one location to another. The command syntax is simple and direct ahead #cksum file name The clear command is
used to delete the terminal screen when you run multiple commands in the terminal the terminal screen is filled. Then use the clear command and enjoy a clean screen again.3#clear13# cmp Command: cmp command is used to compare two byte files. If you find a difference, report the number of bytes and line where the first difference is. If there
are no differences, by default, cmp does not return any output.basic command cmp #cmp file1.txt file2.txt14# comm Command you can use the comm command to compare two row sorted rows. The basic syntax to use this command:#comm file1.txt file2.txt15# cp command: The Cp command is used to copy one or more filesa position in another
position. #cp source/location/destination/location/path If you are copying the file from the current work directory, then give a file name and a source address. #cp destination/location/path file name Use the cp command carefully because it will overwrite the files without asking. It means that if the name of the target file already exists, its data will be
deleted. you can use -i option to request confirmation. This is a great command and can be used in different ways. Here you can read more about Command: In Linux kali operating systems, The crontab command is used to display or change the command table to run by cron. The cron table is the list of scheduled tasks to run at regular intervals on
the Linux system. The demon that reads the crontab and executes the commands at the right time is called cron. Examples of command Crontab #crontab -eEdit your crontab.#crontab -lDisplay ("list") the job of your crontab. #crontab # - Remove your crontab. #crontab # -u technicianustad -eEdit crontab per user technicianustad. 16# Cutting
Command:cut command is used to cut line parts from specified files or piped data and print the result to standard output. Can be used to cut parts of a line for delimiter, byte position and character The basic syntax for the cutting command is as follows: size OPTION... [FILE]... You can use the following and specified cutting command with filedper
example:#cut -f 1.3 file.txt16# Data Command: the date command is used to control the current date and time. [email protected]:~#date 1 09:55:34 IST 2019 [email protected#~:] the date can be changed by following the following code $ date –set=’20 September 2019 13:09′ but the normal user can’t change system time, Then you are thinking
about “howthe time of system” Of-course I will teach you in this article, do not worry about it. Some examples of date command: $ date -d now $ date -d today $ date -d yesterday $ date -d tomorrow $$-d Sunday date $ -d last-sunday17# command dc: The desk calculator works with postfix notation; rather like many HP Calculators. Basic arithmetic
uses standard + – / * symbols but entered after digits. ♪ Dd commanddd stands for the data duplicator, which is mainly used to copy and convert data. but this tool can be used for: Backup and restore an entire hard drive or a partition. Creating virtual filesystems and backup images of CD or DVD called ISO files Copy regions of raw device files such
as MBR backup (master boot record). Convert data formats like ASCII to EBCDIC. Convert tiny to uppercase and vice versa.dd command is not the basic command so you need to be superuser to run it. Syntax dd isdd if= di= [Options]19# df command The df command for Disk Free is used to signal the use of disk space of the file system. Displays the
amount of disk space available on Kali Linux file system. The df command shows how much free disk space we have in our system. simple syntax command:#df20# diff The Diff command is used to display the differences between two files. Basic syntax: command #diff file1.txt file2.txt21# diff3 The Diff3 command is used to show the differences
between the three files. Syntax#diff3 file1.txt file2.txt file3.txt22# dig is a powerful command in Linux kali used for DNS search. Simple and simple use #dig www.domainname.com You will receive all information about the DNS of the website. 23# command dir Commanddir is used to print the list of contents of a directory. Most Linux user uses the
ls command instead of the dir command, but you can use it. Basic syntax:#dir [OPTION] [FILE]Example:#dir /etc24# echo command: View messagescreen The echo command is one of the most fundamental Linux commands used to display a message on the screen. Echo topics are printedstandard output. echo is commonly used in shell scripts to
view a message or issue the results of other commands. Example: #echo Hello world! 25 # Agreed Command The egrep command is used for searching for lines that match a text scheme. Run the game using extended regular expressions. Egrep running is equivalent to performing grep with -E option. Basic example:#egrep “support|help|windows”
myfile.txtSearch for support help models and windows in myfile.txt.26# Run command The Eject command is used to remove a removable media (typically a CD-ROM, floppy disk, tape or JAZ or ZIP disk) under software control. You can expel DVD by pressing a button, but you can remove it without touching button just type the following
command:#eject Use the following command, in case above the command, it does not work:#eject /dev/cdrom#eject /dev/cdrw#eject /dev/dvd#eject /dev/dvdrom#eject /dev/dvdrw #ethtool [ethernet card] If you want to view network usage statistics with ethtool using the following command#ethooo -S eth0where eth0 is a name of the card28#
whoami command: it is looking at something different command, but it is used to tell about you. For example, if you forget “what user is connected?” This command will tell you who you are current.$whoami29# pwd command: pwd command is used for the print job directory. It means “In which position you are“. here the meaning of the location is
directory and sub-directory. The main directory is “/” root directory. Do not be confused with /root directory, this root directory “/root” is home directory for root user. [email protected]:~#pwd /root [email protected]:~# command 30# ls:ls is used the command to view files andwithin a directory. using ‘ls’ without any location lists files and folders
within the current directory. If you want to look up in another directory, you will beto specify the location. $ls$ls /var$ls home/username[email protected:~#] ls Desktop Downloads Pictures Templates virtualbox_6.0.10-dfsg-4kali1.dsc Documents Music Public Videos virtualbox_6.0.10-dfsg.orig.tar.xz [email protected#~:] ls var backups lib ran tmp
cache cd command 31#: cd command is a very useful command and plays a very important role for the Linux user. This command is used to change the directory. And the basic syntax will be as below: cd desired/location If you use empty "cd" without location, then it will move into the user's home directory. so see the power of the cd commands and
