Linux

An operating system (OS) is the software which manages hardware and resources, like CPU, storage and memory. The OS bridges the applications and hardware and makes the connections between all of your software and the hardware resources.

Limited Shell Through this program, you will learn to do the following: Work with processes using fork, pipe, wait, dup2, and the exec system calls.

The implementation of system calls ought to take place in a separate operating system. It's possible that the operating system will choose to implement a system call for its own reasons.
Multithreading: Select all of the following statements that are true. User threads must be mapped onto available kernel threads in order to be scheduled to be assigned to the CPU. A lightweight process (LWP) is a communication interface between different user threads of an application. The Many-to-One multithreading model allows the splitting of processes and threads across multiple CPUs. In the Many-to-Many multithreading model, a process always blocks whenever one of its threads blocks. A context switch between threads can be performed much faster than between processes. One advantage of multithreading is responsiveness, which means that one thread may respond instantly while other threads are blocked or busy doing calculations.

Can you please write C program that will act as a shell interface that should accept and execute a rm[ ] command in a separate process. There should be a parent process that will read the command and then the parent process will create a child process that will execute the command. The parent process should wait for the child process before continuing. This program should be written in C and executed in Linux.
Computer Science Write a “C” program that creates a number of zombies (1 through n) processes as specified in the command line arguments to the program: zombiefier –n 10 creates 10 zombies. Make sure the program cleans up the zombies upon completion. Zombies must remain in the system until a signal (SIGCONT) is sent to zombifier

You are required to write a C program on Unix/Linux in which the parent process creates three child processes, lets them run concurrently, and waits for them to return and prints their exit status. The three child processes are assigned different tasks. Child one is to calculate and display the average mark of a class of twenty students for a unit. Child one is required to get the marks from the standard input (i.e. the keyboard). Child two is to load a program called “wc” (word count) to count file1. Child two is required to get file1 by the command line argument. Child three is to modify file2 by first inserting “this is the updated version.” at the beginning of this file and then replacing all the occurrences of the word “run” by “execute” and “examine” by “study”. You are required to write your OWN program for the file update. Child three is required to get file2 by the command line argument.
The connection between Windows processes and threads has to be illustrated with relevant examples.
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. 2. 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. You will need to use the fork()and not 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. However, you will need to handle the redirection operators…
