c program called shell.exe that will read user input and then decide which system command it will execute and then execute it with all the parameters given. The program basically should call other already made programs and not incorporate the code in the shell.

Example:

C:\> shell.exe > test.txt > wrongComand Command not found > ExiT C:\>

One of the other programs:

int main(int argc, char ** argv[]) //inline paramaters { FILE *sourceFile; FILE *destFile; char *letter = argv[1]; int count = atoi (argv[2]); char *sourcePath = argv[3]; char *destPath = argv[4]; char h[] = "h" char t[] = "t "; int i = 0; char ch[100]; //character maximum of 100 //function to read from bottom up char *my_read(FILE *sourceFile) int x, size; char *buffer; //find source file and seek the end fseek(sourceFile, 0, SEEK_END); size = ftell(sourceFile); //memory allocation size + 1 buffer = malloc((size+1) * sizeof(char)); //for loop for memory allocation for (x=0; x
