Can dashes be escaped in entity names?

[ve3ied]

This may just be a lack of my understanding, but while trying to parse a response to get tag values for a tagname, unfortunately someone used a dash in one of the tagnames which is interpreted by jq. Is there any way to escape this from being interpreted by jq?

I used something like this:

jq '.queries[0] | .results[0] | .tags | .bad-tag | .[]'

..where bad-tag doesn't work. I've also tried: .["bad-tag"] and various other things to try to work around it, but can't find a solution..

Any suggestions?

Actually, I think it does work. I hadn't escaped the variable I used properly in the shell script.

Thanks.

How did you get this to work, please? I have the following problem using a dash in a tag name:

$ cat info.json | jq --raw-output '.messages[0] | .headers | .user-agent '
error: agent is not defined
.messages[0] | .headers | .user-agent
                                ^^^^^
1 compile error

I've tried using backslashes, HTML escapes, and @ symbols.

Found the solution on this page:

cat info.json | jq --raw-output '.messages[0] | .headers | .["user-agent"] '

Right, that's what I did..

Cheers.
