1. First, we create the ;data-maker.sh script. This script introduces several new concepts including the ever fascinating concept of randomization. In computers, or really anything in life, true random events or number generation cannot happen and require several mathematical principles such as entropy. While this is beyond the scope of this cookbook, know that when reusing it randomly or even initially, you should give it a unique initialization vector or seed. Using a for loop, we can build an array of numbers using the seq command. Once the array is built, we choose a "random" value from the array. In each type of file output operation (binary or text), we determine approximately ...
