Sorry if you got this twice!
Hi everyone, for some reason I can't seem to do basic math in this bash
script I'm creating for a class I'm taking. Here's my code
#!/bin/bash
isec=`date +%s`
thisec=$isec*$isec-$isec
I'm just getting the date in seconds, then trying to get a sort of
random number out of it by squaring the result, then subtracting the
original result from the squaring answer (just x²-x). I've tried putting
('s and `s and 's and "s in all logical places in a weak attempt to
guess.
My assignment is to create a script that can play Mastermind, the game
where there's a 4-digit number that is chosen randomly, and a person
guesses what the number is. After each guess the game tells you how many
of the numbers you picked are in the correct place (1's 10's 100's or
1000's) and how many are in the number somewhere, but not in the correct
place.
I've found the $RANDOM builtin, but I need to create a random number
that's 4 digits long. Any help is RIDICULOUSLY appreciated, THANKS!!
Steve
