How can I use wildcards in queries?

For example consider this.

    echo '{"users":[{"name":"s1","id":1},{"name":"s2","id":2}]}'|jid

I can query users[0].id or users[1].id. How can I get all the ids? I tried users[*].id which didn’t work.

In Clojure I use specter [1] for this which is able to handle wildcards using ALL.

jq uses empty square brackets as a way of accessing all of an arrays elements. Not sure if this tool uses the same syntax?

E.g. users[].id

echo '{"users":[{"name":"s1","id":1},{"name":"s2","id":2}]}' |exec tr '{' '\12'|exec sed '/name/!d;s/\"//g;s/}.*//'

output:

   name:s1,id:1
   name:s2,id:2
