Mike,
Unfortunately, that is the crux of the problem. I do have write
permissions, but subsequent to my posting my message, I discovered that my
job was failing with an 'unable to find your tty' error. The error message
makes sense because I was not logged on at the time. However, that is one of
my requirements : my job should be able to work even when I am logged off.
I also had another idea : maybe I could 'cat' my message to the tty. But
I couldnt seem to get this to work.
