Hello Guruz,

Could some please tell me how can I print via shell script �..............� with specific delay of 1 sec per �.�
I tried this, but it's started printing one by one.

Per forum rules, and the benefit of all users, please search the network and the forums before posting a question. Thank you.

Anyway, it should be something like:

while true
do
  sleep 1
  printf "."
done

Thank u so much.
