i've got a string with JSON text that i want to parse

heat@heat-G780 ~ $ data='{"foo": 42, "bar": "less interesting data"}'
heat@heat-G780 ~ $ echo $data|jq '.foo'
42

but then i can't assign this value to a variable

heat@heat-G780 ~ $ foo=$data|jq '.foo'
heat@heat-G780 ~ $ echo $foo
(here's nothing, trust me)

so, how can i assign it to a new variable?

`foo=$(echo $data | jq '.foo')` – Phylogenesis Aug 25 '16 at 15:06
@Phylogenesis oh, many thanks to you! – Aug 25 '16 at 15:08
@Phylogenesis don't forget quotes around `"$data"`. – Tom Fenech Aug 25 '16 at 15:20
