Linux modding questions - extract cats, enable launch parameters

[emptyhead41]

[EDIT: Changed the subject title as I'm encountering more things and figure it 's better to put them all here rather than make a separate post for each. Might as well add any answers I find here as well.]

Apologies if this is answered somewhere already. I did do a search but couldn't find anything.

The XTools1.11 zip only contains windows executables. How do people on linux go about extracting the CAT files?

I can't seem to get launch parameters to work on the linux version. Fixed it.
- On GOG version it creates a shortcut that points to /game_directory/start.sh. Adding launch parameters to this don't do anything. However this script launches 'testandlaunch' in the /game_directory/game/ dir. Add launch parameters to it instead. eg. from /x4 foundations/game/ run "./testandlaunch -skipintro -showfps"

-logfile launch parameter doesn't seem to work on linux (kubuntu 23.10 at least). Just freezes the entire desktop environment.
