I would like to react to each job's completion. I need to accumulate the

with the remaining jobs. I don't think pipe is what I want, but maybe I'm
misunderstanding that feature. Given that parallel is writing joblog (which
I love,btw) I'm wondering if anything could be plugged in there?
Can you make a wrapper like this:

doit() {
   process $1
   analyze output $1
   if good; then
      return 0
      return 1
export -f doit

parallel --halt 1 doit ::: args

If not, please elaborate.

Thanks, yes that might be an option though much must conveyed in "$1".  I'm currently trying a java alternative on this same theme, the meat of which may morph into "analyze output".
