Hello,
i was trying to generate a random string.
Looking for something similar on google, i find this one way:Random.seed!( 0 ) prefix_result = randstring(12) println(prefix_result)I understand that force seed to 0, Ialways get the same string, so I test in this way:
using Random println("--------------------------") #Random.seed!( rand(1:100000) ) prefix_result = randstring(12) println(prefix_result) Random.seed!( 0 ) prefix_result = randstring(12) println(prefix_result) Random.seed!( rand(1:100000) ) prefix_result = randstring(12) println(prefix_result)And i obtein differe behavoiur in June and running as script from command line:
In june i get the same string, if i run again and again my scrip:
-------------------------- 6J6tq8qFzZvo 0IPrGg0JVONT Hw3AOmXRzOiv -------------------------- 6J6tq8qFzZvo 0IPrGg0JVONT Hw3AOmXRzOiv -------------------------- 6J6tq8qFzZvo 0IPrGg0JVONT Hw3AOmXRzOiv julia>In the command line, i get this:

Many thanks for reply.
