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

Your string still has the newline at the end. You could compare with "exit\n" or use something like strncmp(command, "exit", 4). Note that that would accept anything that started with "exit" and ignore the rest.
