scripting Ctrl-D in a shell

Hi, I want to use the "at" command in a loop to start different processes every hour or so, but I don't know how to script a Ctrl-D so I can escape from the "at" after the last command I want to run and then go to the next command in the loop.

Example:

i=1
while [ $i -lt 3 ]
do
j=$((i*60))
at now+"$i"min
cp file$i directory$i
##I want to put the Ctrl-D here so that the at command knows to stop after the cp ##command
Ctrl-D
i=$((i+1))
done


So, can someone please tell me how to script a Ctrl-D??
Thanks so much!

You do not need to use a ^D, because you can phrase the at-command in another way:

Code:
print - "command -options arguments" | at now+${var}min

Try it out on the command line:

Code:
print - "print hello world" | at now+1min

I hope this helps.
