Thanks!
This is what solved the problem.
Seems similar to the Windows exec command.

The only way I found by searching the net in order to have a 1-line
command to set an at task was to use the echo trick and pipe the
output into at as shown.

Since I have 16 such at tasks to create I wanted to write a script for
it.
And then I got into the echo problem...
What I showed here was of course only the first call...


>echo $ATINPUT | $AT

I guess you forgot the eval keyword here... :)

My exit was here in order to stop the script after the first command
when testing.
I do not have an exit otherwise.

Thanks again!
