Shell Programming and Scripting

Hi.
I was testing some staff and wrote simple script, which only writes date to log every 15 seconds.
Like that

#1.sh
while true;do
echo `date` >> 1.log
sleep 15
done

And than i ran this process with `at -s -f 1.sh now`. And now it is running and i don't know how to catch it.
I tryed `while true; do; fuser 1.log done`
but it doesn't show anything.

ps -ef also doesn't show any info on script's filename.

As written in man at you could identify jobs with atq and terminate them with atrm.
