Usage of fgets function in C

Question

One of my assignments in to write my own UNIX Shell. To receive input from the user, I am using fgets to capture the input as a string but I\'m not really sure how it works.

Answer 1

fgets will always include the line termination character in the input string. You can remove any space, including the newline characters, from the end of your "command" by doing:

char command[50];
fgets(command, sizeof(command), stdin);

size_t length = strlen(command);
// Trim off trailing "spaces" including newline characters
while ((length > 0) && isspace(command[length-1]))
      command[--length] = '\0';

printf("Your Command: %s\n", &command); // Include newline now...
// This is computed above...
// int length = strlen(command);

// Continue as before
