open pdf in linux with help of base-macro

In WIndows I use this:

dim oSys as object
dim path as variant
path = “C:file.pdf” (for example)
oSys = CreateUnoService(“”)
oSys.execute(path, “”, 0)

to open a PDF (and Windows finds some installed pdf-reader).

In Linux this does not work.
On a command-line “gnome-open file.pdf” works fine. Evince is the pdf-reader here.
But how do I “wrap” this in a macro, instead of the command-line?

This should work:

Shell "evince /home/YOUR_DIRECTORY/file.pdf"

I believe that is the correct spelling of your document viewer.

Works very well.
Thank you so much!
