They have a tutorial at: https://jena.apache.org/tutorials/sparql.html

Once you've done the <Apache Jena CLI tools setup> we can query all users with Full Name (FN) "John Smith" directly fom the \a[rdf/vcard.ttl] <Turtle RDF> file with the \a[rdf/vcard.rq] <SPARQL> query:
``
sparql --data=rdf/vcard.ttl --query=rdf/vcard.rq
``
and that outputs:
``

| x                             |
=================================
| <http://somewhere/JohnSmith/> |
