Thanx Cameron,
I'm perfectly happy now. Didn't know about PROMPT_COMMAND.

I use this slightly modified version:

function job_test {
  if [ -z "$(jobs -p)" ] ; then
    IGNOREEOF=0
  else
    IGNOREEOF=999999
  fi
}
PROMPT_COMMAND=job_test

since "set -o ignoreeof" only ignores the first 10 ^D and I want it
to be as strict as possible.

Didn't notice the glitch you mentioned, but I'm sure I can live
with it very well.

I also want to thank you, that you read my mail even though
it was a bit noisy (as I noticed right now, I started the body
with the wrong text). Apologies to anyone else who felt disturbed
by my misbehaviour.

Cheers, Michael
