passing arguments to jq filter

Question

Here is my config.json:

{
    \"env\": \"dev\",
    \"dev\": {
        \"projects\" : {
            \"prj1\": {
                \"dependencies\": {},
                


        

Answer 1

The jq program .dev.projects."$v" in your example will literally try to find a key named "$v". Try the following instead:

jq --arg v "$PRJNAME" '.dev.projects[$v]' config.json
