Command line render just quits. No error? Here's the output....

When I do a command line render, it quits immediately, but I don’t see an error in the output. It’s supposed to render 180 frames. I bet I’m doing something wrong, but what?

Here’s what I see (it’s my command line, followed by the output as it quits immediately):

Blender quit

I just solved this myself. I needed to include the -a flag, to tell it to render all frames. Because I left that out, and I didn’t include any other commands telling it which frames to render, it rendered nothing and quit.

Ideally, it could have mentioned something like “0 frames specified; 0 frames rendered” but I’m grateful for what I’ve got. It’s rendering in the background and I’m able to work on other things. Splendid!
