> Summary: I think the {{post}} bash script tries to detect stdin the wrong
> way.
> If I run "post -h" I see some examples, to include this:
> {code}
> echo '{commit: {}}' | bin/post -c my_collection -type application/json -out
> yes -d
> {code}
> However if I try it, Solr returns this error: {{Cannot parse provided JSON:
> JSON Parse Error: char=<,position=0 BEFORE='<' AFTER='add/>'}}
> I see that {{post}} is sending an {{<add />}} in certain cases, but it's not
> supposed to when the mode is stdin. Looking closer, it appears to be because
> of this line:
> {{if [[ -s /dev/stdin ]]; then}}
> If I change it to this (which I figured out after googling around; I'm no
> bash expert!):
> {{if [[ ! -t 0 ]]; then}}
> Apparently '0' represents stdin. It works for me. [~thelabdude] might you
> take a look? I'd be happy to add a formal patch & commit for this trivial
> change but it really needs other eyes.
