my approach will be  your json example is not well formed   guess thats only a sample   jq   Front       Name  Out  In  Groups    join        front json   gt  output txt   returns something like this    new domain com-80 8 8 8 8 192 168 2 2 80 192 168 3 29 80 192 168 3 30 80   new domain com -443 8 8 8 8 192 168 2 2 443 192 168 3 29 443 192 168 3 30 443    and grep the output with regular expression

While both of the above answers work well if key value are strings  I had a situation to append a string and integer  jq errors using the above expressions    Requirement  To construct a url out below json  pradeep seleniumframework gt curl http   192 168 99 103 8500 v1 catalog service apache-443   jq   0      Total      Received   Xferd  Average Speed   Time    Time     Time  Current                                  Dload  Upload   Total   Spent    Left  Speed 100   251  100   251    0     0   155k      0 -- -- -- -- -- -- -- -- --  245k      Node    myconsul      Address    192 168 99 103      ServiceID    4ce41e90ede4 compassionate wozniak 443      ServiceName    apache-443      ServiceTags          ServiceAddress          ServicePort   1443     ServiceEnableTagOverride   false     CreateIndex   45     ModifyIndex   45     Solution   curl http   192 168 99 103 8500 v1 catalog service apache-443   jq    0     http        Address             ServicePort

You can use addition to concatenate strings      Strings are added by being joined into a larger string    jq   users      first          last    The above works when both first and last are string  If you are extracting different datatypes number and string   then we need to convert to equivalent types  Referring to solution on this question  For example   jq   users      first           number tostring

I got pretty close to what I wanted by doing something like this  cat my json   jq   my prefix      primary key          sub prefix          -      sub key     tr -d        The output of which is close enough to yaml for me to usually import it into other tools without much problem   I am still looking for a way to basicallt export a subset of the input json
