Test that the value held in variable "i" (typically used for an index variable) is less than 3. Note that variable i is incremented at the end of the loop, increasing its value by 1. So, it loops 3 times and is used as the index of the array called "log", thus displaying its contents.

You could use (( $i < 3 )) which may make more sense?
