Counter

AMMullan · 10-23-2003, 05:55 AM

I am trying to make a little shell script and wanna have a little couter in it, so the user might input their name and then the script will countdown and do something.

What's the best way of doing this?

Oh, when I say counter I mean 5... 4... 3... not the sleep command

Code:

#!/bin/sh

echo Start
count=5
while [ $count -gt 0 ] ; do
    echo -n "${count}.."
    count=$((count - 1))
    sleep 1
done
echo
echo Poof!

How to rid of the cursor?
I don't know.
You'll need something like the "dialog" utililty.
