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

From the fgets manual page:

fgets() reads in at most one less than size characters from stream and stores them into the buffer pointed to by s. Reading stops after an EOF or a newline. If a newline is read, it is stored into the buffer. A '\0' is stored after the last character in the buffer.

Bottom-line: you have an extra newline at the end of your string when comparing.
