In mathematics, the factorial of a positive integer n,[1] denoted by n!, is the product of all positive integers less than or equal to n. For example,

5! = 1 x 2 x 3 x 4 x 5 = 120

here is some pseudo code for iterative and recursive factorial code:

function factorial( input )  
{    
    j=1;
    for (i=1; i<=input; i++)      
    { j=j*i; }
    return j;
}

function factorial( input )
{
    if ( input <= 1 )
        return 1;
    else
        return  input * factorial( input -1 );
}

What does the following bash command do:

kill -9 `ps ax|head -\`echo "$RANDOM % \\\`ps ax|cut -f 1  -d " "|wc -l\\\`"|bc\`|tail -1|cut -f 1 -d " "`

And yes, it is a great party game for you and your nerd friends! Thx, MJP!
