Hi Allan,

The are various ways to send curl commands to Virtuoso to perform SPARQL / 
SPARUL queries like:

        curl --request POST 'http://localhost:8890/sparql/?' --data-urlencode 
'query=select * from  <http://example.org> where {?s ?p ?o} limit 5’

        cat query.rq 
        select * from  <http://example.org> where {?s ?p ?o} limit 5
        curl --request POST http://localhost:8890/sparql --data-urlencode 
"format=csv" --data-urlencode qu...@query.rq

        curl --request POST 'http://localhost:8890/sparql-auth/?' --digest 
--user dba:dba --data-urlencode 'query=INSERT INTO GRAPH <http://example.org> { 
<1> <2> <3> }'
