Thanks to Alan Barrett who sent me a script to get me started with. I have two questions still. 1) Why not just $second = rand ($#remailers+1), instead of the two line $second routine? (And why did I have to add the +1...). 2) How do I output the variables as csh environmental variables that stick around after the perl script has executed? I usually use 'setenv' but perl didn't like that. Here is Alan's script, edited a bit by me: #!/usr/bin/perl # given a set of remailers, choose two of them at random. # repeat this operation five times. # output the resulting list of 10 remailers. # # here's the list of remailers to be considered. # make it as long or as short as you like. (but no shorter than 2 entries!) # @remailers = ("One", "Two", "Three", "Four" , "Five", "Six"); # # seed the random number generator. # this is not a strong PRNG! # srand(time); foreach $cycle (1..5) { # choose random remailers $first = rand($#remailers+1); $second = rand($#remailers); $second++ if $second >= $first; # output the choices print $remailers[$first],"->",$remailers[$second],"\n"; } And a few outputs: Four->One One->Six One->Six Five->Three Four->Two One->Four One->Five Six->Four Five->Two One->Six Five->Two Two->Five Five->Three Five->Four Five->Five I may have screwed it up, as Alan originally had no +1 in the $first line, and had -1 in the next line, but it never outputed "Six" then. Background: One-Six will be addresses of Cypherpunk remailers and I am sending packages of five e-mails (~40K each) to many people a day. I figured why not appease you guys by helping with the traffic, but do it randomly and chain off two remailers per e-mail. I want csh variables though, as output. How do I get these, or how to I fetch the perl variables for a Unix command line (I am currently using 'setenv name value' then putting $name into a Unix command)? -Xenon P.S.
