I've echoed out the contents of $cmd in my testing. It does contain
exactly what is intended:
echo "podcast -c abc123 | at 10:01 am"

Also, the command I'm trying to execute works perfectly from the CLI with
the same (appropriate) values.

I'm thinking that there might be a permissions issue but I'm unable to
obtain the error message from the passthru command.

I suppose next I will try to create a small php script to emulate this
from the CLI and perhaps them I will see the error (if any).

Thanks
