## Exercise 2

 1. Let's try to write a C program now. You can refer to the two
    programs I have shown you today when writing the new one.
 2. Let's call the program ‹kitten.c›, because it'll be like a very
    tiny version of ‹cat›. It should do the following:
    
    ◦ check that it has at least 1 argument
    ◦ if so, take that to be a file name and open it
    ◦ read the first kilobyte of the file
    ◦ and print it
    ◦ don't forget to close the file descriptor

 3. Compile and run your program.
 4. As a bonus, you can try the following:
    
         $ ./a.out ../01/oslist.csv | cut -d, -f3
    
    We can pipe the output of our little program to other commands,
    just as we could with ‹cat›.

Let's turn to system libraries for a bit:

    $ cat syslibs.txt
