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

Probably the easiest way to handle this is to switch to using scanf to read the input:

char command[51];

scanf("%50[^\n]", command);

if (0 == strcmp(command, "exit"))
    do_something();
