improved spinner

[panv-00]

If you have unicode support in your terminal, you could make the spinner more aesthetic as below:

#!/usr/bin/bash

# filename: ~/.local/bin/spin

# Use in scripts like:
# spin &
# SPINNER_PID=$!
# disown
# # run here any task that would take time in the terminal
# kill $SPINNER_PID
# wait $SPINNER_PID 2>/dev/null

spinner_frames=("⠋" "⠙" "⠹" "⠸" "⠼" "⠴" "⠦" "⠧" "⠇" "⠏")

BLUE="\e[34m" # or use any other color, or even no color at all
RESET="\e[0m"

while true; do
  for frame in "${spinner_frames[@]}"; do
    echo -en "\r${BLUE}${frame} ${RESET}" # add a space after the spinner -- as gap
    sleep 0.1
  done
done

I'll add this in as a new script! Thank you for sharing
