Using jsonmunge

If person.json contained

   {"name": "Doe, Jane", "email":"jd@example.org", "age": 42}

and the template, name.tmpl, contained

   {{- .name -}}

Getting just the name could be done with

    cat person.json | jsonmunge name.tmpl

This would yield

    "Doe, Jane"

example files

• person.json
• name.tmpl
• jsonmunge-demo.bash
