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.

Hello im looking for some direction as to how to approach a homework question. At the moment im stuck because im trying to use scanf() with execlp in order to solve the question. Here is the question: Write a special simple command interpreter that takes a command and its arguments. This interpreter is a program where the main process creates a child process to execute the command using exec() family functions. After executing the command, it asks for a new command input ( parent waits for child). The interpreter program will get terminated when the user enters quit. I'm just looking for direction, not to have someone solve it.

Write a Java application that will accept two filenames (text files) as command line arguments and use two threads to read contents from the two text files. Each of the threads should sleep for a random time after displaying filename with each line.

Write a C program that, given a text file, constructs Huffman code based on the character frequencies of the file and then encodes the file accordingly. The executable must accept the following command line options:• -i filename for the input file • -o filename for the output file

Description:The project I am working on needs to demonstrate how two processes (parent and child) can communicatethrough a shared memory region, with the child process writing a value to the shared memoryand the parent process reading that value.  This is my code and I wont run. Can you help:  #include <stdio.h>#include <stdlib.h>#include <sys/types.h>#include <sys/ipc.h>#include <sys/shm.h>#include <unistd.h> #define SHM_SIZE 1024  /* shared memory size */ void error_exit(const char *msg) {    perror(msg);    exit(EXIT_FAILURE);} int main() {    key_t key;    int shmid;    char *data;     // Create a unique key for shared memory    if ((key = ftok("shared_memory.c", 'R')) == -1) {        error_exit("ftok");    }     // Create the shared memory segment    if ((shmid = shmget(key, SHM_SIZE, 0644 | IPC_CREAT)) == -1) {        error_exit("shmget");    }     // Attach the shared memory segment to our data space    data = shmat(shmid, (void *)0, 0);    if…

You'll write a C++ program to demonstrate thread synchronization. Your main function should first create an empty file called *sync.txt*. Then it will create two separate threads: *Thread-A* and *Thread-B*. Both threads will open *sync.txt* and write to it simultaneously.   *Thread-A* will write the numbers 0 through 9, a total of fifty-thousand times in nested `for` loops, then exit. In other words, print the numbers 0 through 9 over and over again, with each run on a separate line, for 50,000 lines. Here's an example of one such line: ```text 0 1 2 3 4 5 6 7 8 9 ```   Somewhat similarly, *Thread-B* will write the letters A through Z fifty-thousand times in nested `for` loops, then exit. In other words, print the letters A through Z over and over again, with each run on a separate line, for 50,000 lines. Here's an example of one such line:   ```text A B C D E F G H I J K L M N O P Q R S T U V W X Y Z ```   Do not write each line as one long string. You must write each character to the…

Write a shell program that renames all files in the current directory. It should remove all vowels from the filenames. For example, apple.txt should be renamed ppl.txt. If the resulting filename is an empty string, then the file should not be renamed.

Part II: Processes and Threads. Write a C program that will creates a child process. The child will ask the user to enter an integers x and then sends it to the parent via pipe. The parent should print your student's ID if x > 0 or your full student name if x 0 and 01998877 if x <= 0. Note: cach student should print his own id and name as they appear on the UMS. The inter-processes communication should be using pipes.

You shall implement a Microshell, “MSH”.  MSH shall provide the following functions: Provide a shell-like interface for launching new programs: When MSH starts running, it will print a prompt "cssc0000% " (replace cssc0000 with your username) and then wait for the user to type in a file name. Note, MSH will NOT have any shell built-in functions (such as cd, setenv, printenv, bg, fg, etc), with the exception of #5 (below). When the user enters a filename and hits the “enter” key, MSH then reads the filename entered and determines if the file is an executable file. If it isn't, MSH will print a useful error message to the user and then return to #1 above (display a new prompt and wait for user input). If it is an executable file, then MSH will create a new process and run this program in the new process. Note – you will need to determine whether the filename is a fully qualified path name or if the file needs to be searched for (fully qualified pathnames begin with a slash (i.e. "/"),…

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. 1. Interactive Mode In interactive mode, you will display a prompt (any string of your choosing) and the user of the shell will type in a command at the prompt.
