I have a Problem in parsing OWL to Prolog Triples

edit

Hi all,

(((1)))I do not have more experience in KnowRob, so I now try to run command and see its effects and so on I was trying to parse Owl file into Prolog so I use this command

 owl_parse('home/amal/pizza.owl', false, false, true).

I get this error

   bash: syntax error near unexpected token `'home/amal/pizza.owl','

1- What is the Problem

2- I do not Understand Why false false true in the command ?!

(((2))) It always give me false, I flow this tutorial (Reasoning about objects at knowrob wiki) and also get false, so what is the problem

Terminal:

amal@amal-HP-G62-Notebook-PC:~$ roscd knowrob_tutorial
