I'm having a hard time getting the value of an environment variable ($GHREPO) in a quoted string. Here is the command I'm running. I'm trying to make a directory with the value of j["ChgSub"][$GHREPO][0]["Major"], $GHREPO being an environment variable.

 mkdir `cat ../dummy.json | ruby -rjson -e 'j = JSON.parse($stdin.read); puts j["ChgSub"][$GHREPO][0]["Major"].to_s'`
