=> More information.

• Render all frames of an animation in the background, without loading the UI (output is saved to /tmp):

blender --background {filename}.blend --render-anim

• Render an animation using a specific image naming pattern, in a path relative (//) to the .blend file:

blender --background {filename}.blend --render-output //{render/frame_###.png} --render-anim

• Render the 10th frame of an animation as a single image, saved to an existing directory (absolute path):

blender --background {filename}.blend --render-output {/path/to/output_directory} --render-frame {10}

• Render the second last frame in an animation as a JPEG image, saved to an existing directory (relative path):

blender --background {filename}.blend --render-output //{output_directory} --render-frame {JPEG} --render-frame {-2}

• Render the animation of a specific scene, starting at frame 10 and ending at frame 500:

blender --background {filename}.blend --scene {scene_name} --frame-start {10} -e {500} --render-anim

• Render an animation at a specific resolution, by passing a Python expression:

blender --background {filename}.blend --python-expr '{import bpy; bpy.data.scenes[0].render.resolution_percentage = 25}' --render-anim

• Start an interactive Blender session in the terminal with a python console (do import bpy after starting):

blender --background --python-console
