Can you please write C program that will act as a shell interface that should accept and execute a cp[ ] 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.
Please write the program and explain-line-by-line. Thank you! A shell interface gives the user a prompt, after which the next command is entered. The example below illustrates the prompt osh> and the user's next command: cat prog.c. (This command displays the file prog.c on the terminal using the UNIX cat command.) osh>cat prog.c One technique for implementing a shell interface is to have the parent process first read what the user enters on the command line (in this case, cat prog.c) and then create a separate child process that performs the command. Unless otherwise specified, the parent process waits for the child to exit before continuing. This is similar in functionality to the new process creation illustrated in Figure 3.9. However, UNIX shells typically also allow the child process to run in the background, or concurrently. To accomplish this, we add an ampersand (&) at the end of the command. Thus, if we rewrite the above command as osh>cat prog.c & the…

Write a menu driven shell script to accept either a file name or directory name and perform theoperations as per the menu. When the user runs the script, three main menu options are displayed:1: File related operation2: Directory related operation3: ExitWhen user enters option1, file related menu is displayed i.e.,1: Write data in to file2: Display the contents of the file3: Delete the file4: Go back to main menu
ps and top are two common command for managing processes. Top can only display processes, but ps can kill and renice them. Is this correct or incorrect?
users' programs can make system calls, but system calls cannot be called directly, since all system calls are executed in the kernel mode and there is no direct connections between user & kernel. In 1-2 paragraph(s) explain the calling of system calls from user to the kernel. That is, explain how kernel know which system call user wants to execute.
Which one of the following is not true? a. User threads are implemented using System calls b. Kernel threads slower than User threads c. Kernel threads implemented VIA system call d. User threads implemented using user-level libraries without a system call

You must locate a procedure for which you only know a portion of the name.The Issue: You "sort of" know the name of the process you're looking for. Because of the highly inconsistent naming convention of the procedures in the Windows API, this is a frequent problem for Microsoft Windows programmers. No superior are UNIX programmers. Only the inconsistency in naming conversions is constant; the only issue is that UNIX enjoys leaving letters out of system call names. (for example, creat).
