Jul 10 12:15:10 <sixwheeledbeast> can random be used in a loop on the shell without having the same number come up
Jul 10 12:17:11 <KotCzarny> ?
Jul 10 12:17:25 <KotCzarny> try: echo $RANDOM
Jul 10 12:17:32 <KotCzarny> works in bash
Jul 10 12:17:34 <sixwheeledbeast> to avoid xy I need to pull a random list of say 50 integers from a pool of 01-99 . I beleive RANDOM will repeat them if in a loop
Jul 10 12:17:48 <KotCzarny> it returns 0-32767 i think
Jul 10 12:18:04 <KotCzarny> up to you to scale it to range you need
Jul 10 12:18:07 <sixwheeledbeast> i want no duplicates
Jul 10 12:18:15 <KotCzarny> thats not random then
Jul 10 12:18:47 <KotCzarny> what you need is to create an array with 99 elements, then shuffle it
Jul 10 12:18:57 <sixwheeledbeast> well I suppose so but that's what i am looking for
Jul 10 12:19:12 <sixwheeledbeast> i see is array the best way you think?
Jul 10 12:19:39 <KotCzarny> otherwise you have to keep different array with 'used' numbers anyway
Jul 10 12:19:59 <KotCzarny> and having to scan through it on every new return
Jul 10 12:20:38 <sixwheeledbeast> I suppose so. I didn't think of it like that. i was hoping for a shell function already there :)
Jul 10 12:21:13 <KotCzarny> i havent seen such functionality in bash
Jul 10 12:21:44 <KotCzarny> anyway, your problem is 'shuffle deck of cards then deal them'
Jul 10 12:21:54 <KotCzarny> taught in schools often
Jul 10 12:22:06 <KotCzarny> so there should be lots of examples for different languages
Jul 10 12:22:10 <sixwheeledbeast> np array it is then. school?
Jul 10 12:22:26 <KotCzarny> ya, it101
Jul 10 12:23:10 <sixwheeledbeast> school is long behind me we where lucky to have working ones in my era
Jul 10 12:23:39 <KotCzarny> but as i've said, google: deal shuffled deck of cards in bash
Jul 10 12:26:48 <Maxdamantus> or a more interesting way of looking at it: find an information densitity preserving encryption, and encrypt all possible inputs in a predictable sequence.
Jul 10 12:27:08 <KotCzarny> or basically: shuffle in bash
Jul 10 12:27:13 <Maxdamantus> basically, encrypt(0), encrypt(1), encrypt(2), .. encrypt(n)
Jul 10 12:27:31 <sixwheeledbeast> yep i am waiting for something to render so can't open a browser at the moment, hence I thought I'd ask the question having used random before.
Jul 10 12:27:53 <KotCzarny> swb: but it's better to use any scripting lang, perl/php/python
Jul 10 12:28:03 <KotCzarny> whichever you are best in
Jul 10 12:28:25 <KotCzarny> at some point you will have to switch to it when adding functionality
Jul 10 12:28:44 <Maxdamantus> anyway, if you want a sequence of numbers in a random order: seq 99 | sort -R | head -50
Jul 10 12:29:23 <KotCzarny> wow
Jul 10 12:29:24 <sixwheeledbeast> only ever used bash for most things but i can have a look in python if necessary.
Jul 10 12:29:30 <KotCzarny> i forgot sort has shuffle
Jul 10 12:29:33 <Maxdamantus> (`seq 99` is a bit weird; I suspect what you really want is either `seq 0 99` or `seq 100`, which both emit 100 numbers (`seq 99` emits 99 numbers))
Jul 10 12:30:06 <sixwheeledbeast> oh useful ty :)
Jul 10 12:30:46 <KotCzarny> seq -f '%02.0f' 1 99|sort -R
Jul 10 12:30:47 <KotCzarny> done
Jul 10 12:31:55 <KotCzarny> if you want only 50 of them, add |head -50
Jul 10 12:33:05 <sixwheeledbeast> oh i see you have used the format flag to have 2sf nice
Jul 10 15:20:10 <KotCzarny> Mangy_Dog: pink screen on hdmi means hdmi pixel format failed
Jul 10 15:20:14 <KotCzarny> erm, wrong chan
