hi,
i am looking to find out how to make the cursor spin to show that you are waiting for a process to finish.

i see it when knoppix is booting.

looks like these characters.

This is a little try :

Code:

clear
for i in  '|' '/' '-' '\\' '|' '/' '-'; do
    tput cup 4 20
    echo $i
    sleep 1
done

Hi,

Something like this maybe:

Code:

#!/bin/sh

sleep 10 &
pid=$!

printf "Processing |"
rotate='|/-\'

while kill -n 0 $pid 2>/dev/null; do
    rotate="${rotate#?}${rotate%???}"
    printf '\b%.1s' "$rotate"
    sleep 1
done
echo ''

wait $pid

echo "All done"

Hope this gets you going again.
