Hi

My friend wrote this particular script and won't tell me what it does, and when I run it I don't understand it.

What does the entire script do with specifics please.

Thanks
Bob

#!/bin/bash
current=0
while [ $SECONDS -le 10 ]; do
if [ $SECONDS -eq ${current} ]; then
echo ${current}
current=$((${current}+1))
fi
done
