jq binary package in Ubuntu Mantic s390x

 jq is like sed for JSON data – you can use it to slice
 and filter and map and transform structured data with
 the same ease that sed, awk, grep and friends let you
 play with text.
 .
 It is written in portable C, and it has minimal runtime
 dependencies.
 .
 jq can mangle the data format that you have into the
 one that you want with very little effort, and the
 program to do so is often shorter and simpler than
 you’d expect.
