What I was really after was that the . printed with the 2 second delay. If the last puts flushes the prior prints, then they all show up at once, instead of at 2 second intervals.

What happens if you …

5.times {
print “.”
sleep 2
}
puts “:”

On my system, the last ‘puts’ flushes the prior prints.

I tried on my computer. That’s no problem for prints to print a dot every 2 seconds. And then I check the value of STDOUT.sync, it’s true.
So I think the value maybe vary in different systems. It would be better to check it before writing this kind of codes.

Thx for ‘STDOUT.sync = true ‘ because puts and print waits for 10 seconds and then prints 5 dots.

I don’t know why my ruby do somethings like that when you say that is a difference between puts and print.

But all is fixed thx to you!!

PS: Sorry for my english

Wow that’s cool. i’d imagine it flushes because of the added “\n” at the end? Nice tip
