Thanks for this Charles. With your last command

--8<---------------cut here---------------start------------->8---
wget -q -O - http://www.bbc.co.uk/radio4/programmes/schedules/fm/this_week.json | jq '.[] | .[] | .[] | .[] | .programme as $P | $P.display_titles.title,$P.short_synopsis,$P.pid' | tail - 6

--8<---------------cut here---------------end--------------->8---

It is failing for me  saying

╭────
│parse error: Invalid numeric literal at line 1, column 10
╰────

Presumably its referring to "-O", but what should it be please to
get it working properly?

Thanks
Sharon.
