How to make a blinking printf command (using tput) stop manually after a while in bash (Ubuntu 18.04)?

Question

I know that I can use the below command to blink a prinf or an echo command but how to stop it after a while or after a process is complete? I am writing a script and the blinking would indicate a process is being executed, once it stopped the user knows that step is completed.

BLINK=$(tput blink)
NORMAL=$(tput sgr0)
printf "${BLINK}${GREEN} ------- installing something -------  \n\n${NORMAL}"

Answer 1

I use...

printf "Normal \e[5m\e[31mBlink\e[0m\n"

...and got it from: https://misc.flogisoft.com/bash/tip_colors_and_formatting

So i think you need the \e[0m to end up with normal output.
