The largest change was due to modifying `ioccc.css` that resulted in all year and entry tarballs being modified. Ran `make update` to perform the above.
To build:
make all
To use:
./korn
Judges' remarks:
The Judges believe that this is the best one line entry ever received. Compile on a UNIX system, or at least one using a C implementation that fakes it. Very few people are able to determine what this program does by visual inspection. I suggest that you stop reading this section right now and see if you are one of the few people who can.
Several points are important to understand this program:
-
What is the symbol
unixand what is its value in the program? Clearlyunixis not a function, and sinceunixis not declared to be a data type (such asint,char,struct foo,enum, ...) what mustunixbe? -
What is the value of the symbol
"have"? (hint: the value is NOT 4 characters, or'h', or a string) Consider the fact that:
char *x;
defines a pointer to a char (i.e. an address), and that the = assigns
things of compatible types. Since:
x = "have";
is legal C, what type of value is "have"?
- Note that the following expressions yield the same value:
x[3] *(x+3) *(3+x)
since addition is commutative. What can be said about this value?
3[x]
David Korn's /bin/ksh provides us with a greatly improved version of the /bin/sh. The source for v7's /bin/sh greatly inspired this contest.
