I have installed Calligra using the below link on Ubuntu:

http://community.kde.org/Calligra/Building

Now I want to check the utility of calligra by converting any doc file to pdf format. I need some test code to check this. Can someone provide any reference on this.

Regards, Ankit

Moved to the Calligra forum.

You can use the calligraconverter tool for this. Works like this:
calligraconverter /path/to/your/file.docx newfile.pdf

But I get an error saying calligraconverter command not found although the executable exists in bin directory.
