Where does YoHo Go?
Suppose that file descriptor is connected to stdin, that file descriptor 1 is connected to the terminal screen, that file
descriptor 2 is connected to stderr, that file descriptor 4 names a read connection from file1 and that file descriptor
5 names a write connection to file1.
Suppose that, in this situation, dup2 (2,5) is called.
If write (5, "YoHo", 4); is then executed, where does YoHo go?
To the terminal screen!
To file1!
Nowhere, 5 is now an unused file descriptor!
