Terminal usage export to pdf

[edsousa84]

Hello I have a question about the terminal usage.

I am trying to make a script to make the pdf instructions export of several files.
For now I am trying to figure out the way to export one ldr file to pdf (The ldr already has all the lpub)

I am using the following command: (using -o and -of)
/opt/lpub3d/LPub3D-2.4.7.75.3551_20230905-x86_64.AppImage -o /home/edu/workspaces/OwnProjects/Lego/Brands/ph/ph.ldr -of /home/edu/workspaces/OwnProjects/Lego/Brands/ph/outputpdf.pdf

Is there any extra parameter or anything that I am missing?
