convert the following program into a shell script, including redirection of input and output, pipes, and background jobs.: #define TRUE 1        while (TRUE)   /* repeat forever */     {          type_prompt(); /* display prompt on the screen */         read_command(command, parameters); /* read input from terminal */         if (fork() != 0)   /* fork off child process */         {             /*Parent code.*/            waitpid(1, &status, 0); /* wait for child to exit */         }         else          {            /* Child code. */            execve(command, parameters, 0); /* execute command */         }     }

Write the C program that accepts two arguments. The arguments are the name of two executable scripts located in the current folder. The child must execute the first argument and the parent must wait for the child to complete and then execute the code given in the second argument.

26. Semophores are used to solve the problem of a. race condition b. process synchronization c. mutual exclusion d. belady problem

Please write a C program.   Consider the following code snippet in your main function -a = fork();b = fork();c = fork();Now, write the full program, that will check the children’s PID and if it is odd then the processwill create another child process. Lastly, print how many processes have been createdconsidering the first parent process

THIS IS A COMMON TRANSITION WHERE THE CURRENTLY RUNNING PROCESS HAS REACHED ITS MAXIMUM ALLOWABLE TIME FOR EXECUTION. Select one: a.RUNNING --> READY b.READY --> RUNNING c.RUNNING -> BLOCKED d.RUNNING -> EXIT

Multi-tasking can not be achieved with a single processor machine.  True  False       2. Async/Await is best for network bound operations while multi-threading and parallel programming is best for CPU-bound operations.  True  False     3. The following is a characteristic of an async method:The name of an async method, by convention, ends with an "Async" suffix.  True  False   4. Using asynchronous code for network bound operations can speed up the time needed to contact the server and get the data back.  True  False     5. Asynchronous programming has been there for a long time but has tremendously been improved by the simplified approach of async programming in C# 5 through the introduction of:  The Task class  True  False

Please answer this question

Select all statements below that are true O A set of processes is in a safe state S if S is not a deadlock state and any state T reachable from S is not a deadlock state. In order for a deadlock to occur, only one of the four conditions necessary for deadlocks to occur must be satisfied. O A deadlock means that at least two processes cannot continue working because they are waiting for each to make resources available. о One of the the four conditions necessary for deadlocks to occur is non- preemption. Interrupts, messages, and signals are examples of consumable resources. Reusable resources are produced and consumed dynamically. QL - DELL W

Write a program i.e. is a version of a shell that can take command(s) from the user and execute them on behalf of the user (by spawning a child process to execute the command on behalf of the parent process). It can only execute a few commands as listed below: [+] mkdir [ ... ] [+] ls [] [+] cp [+] mv [ ... ] [+] rm where parameters enclosed in [ ] are optional parameters. Note that multiple commands are recognized by the shell if each command is delimited by ";". These commands will be executed one after the other. Write a C program will act as a shell interface that should accept and execute each 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. Your program should mimic the Linux terminal. This program should be written in C and executed in Linux. You are required to implement five…

Write a C++ source code to achieve following design specifications;  A secure login screen which allows only the user to enter the system (You canprovide any user name and password). Any other user must be greeted with a warning message reading ‘Incorrectusername/password. Please try again’ A maximum of only three login attempts must be given after which the system mustexit. The system must clear the screen after logged to the system. Once the user has successfully logged in, he/she must be greeted with a messagereading “Welcome to System”
