I have connected to a port like this:
nc hello-world.mygame.com 2000
which opens a small game like this:
Please enter your name
a
hello a,
Now I know that a specific number of repeated "a" 's will give special output, how can I iterate over them easily (a then aa then aaa and so on) to get to that special output?
My first try:
awk 'BEGIN{for(i=1; i<=30; i++){s=s "a"; print s}}' | nc hello-world.mygame.com 2000
But it only submits a as input, how can I let it wait for others? I don't know how to use expect here?
My second try:
for x in a aa aaa; do echo $x | nc hello-world.mine.com 2000 done
