Automatic start on specified directory (command line)

Hi all!

I want start a session on specified directory with command line.
And I can't do that...

I try:
But nothing...

I don't use synchronise because I want just start on the directory.

When I use the GUI, on Environment/Directories options, It's work perfectly if I indicate the Remote directory without Local directory. But I can't find the associated command line...

Any idea?

Many thanks!
