You are creating a shell based on the description given in Chapter 2 Part A (page 77) in the Kernel Projects book. Your shell will parse an input. The first argument is the command to be run. The entire command will be read from the user, after a prompt is printed out. Your command will be limited to 200 characters and it will have no additional spaces in the command. You need to place your program in a loop such that it will re-read a new command after the previous command has terminated. You must use the system calls fork, execv and wait. You may use the string functions strcat, strlen and strncmp. The rest should be done by hand. A starter filePreview the document has been provided that includes the recommended order in which you should complete each step of the program. It can be found in the Files page, as well as an example of printing the environment variables. Examples:

  • . - Copy and paste the parser you wrote from Project Part 1 here - You may have to make a few modifictions to make it work with this function
    truewriter | Nov 11, 2020, 08:48 AM
  • #include <stdio.h> #include <stdlib.h> #include <string.h> void show(char *arg1, char *arg2); int main(int argc, char *argv[]) { if( argc == 3 ) { show(argv[1],argv[2]); // calling show method with command line arguments } else{ printf("Only two arguments Acceptable"); // if arguments are less or more than two } return 0; } void show(char *arg1, char *arg2){ //copying command line argument arg2 into str char *str = (char *) malloc(strlen(arg2)*sizeof(char)); strcpy(str,arg2); //second command line argument arg1 i.e. delimeter char ch = arg1[0];
    User_32450 | Nov 11, 2020, 20:44 PM
  • //creating string char* ss = calloc(10, sizeof(char) ); for(int i=0;i<strlen(str);i++){ //if str[i] is a delimeter it will print string before that delimeter and length of that string //will also blank the string ss if(str[i]==ch){ printf("%s length ",ss); printf("%lu\n",strlen(ss)); ss = calloc(10, sizeof(char) ); } //if delimeter is not found it will keep putting characters into string ss else{ char cha = str[i]; strncat(ss,&cha,1); } } //will print final value because for loop will miss this value printf("%s length ",ss); printf("%lu\n",strlen(ss)); }
