Read just reads a block of data; in this case, 19 bytes worth.  You're then
passing this to puts, which expects a NUL-terminated string.  Your code
should instead look like this:

    char buffer[20] = read(file, buffer, 19);
    buffer[19] = 0; /* now it's NUL-terminated */
    puts(buffer);

Note you should also be checking the return value of the call to read to
check for errors.
