# blender > Command-line interface to the Blender 3D computer graphics application. > Arguments are executed in the order they are given. > More information: . - Render all frames of an animation in the background, without loading the UI (output is saved to `/tmp`): `blender -b {{filename}}.blend -a` - Render an animation using a specific image naming pattern, in a path relative (`//`) to the .blend file: `blender -b {{filename}}.blend -o //{{render/frame_###.png}} -a` - Render the 10th frame of an animation as a single image, saved to an existing directory (absolute path): `blender -b {{filename}}.blend -o {{/path/to/output_directory}} -f {{10}}` - Render the second last frame in an animation as a JPEG image, saved to an existing directory (relative path): `blender -b {{filename}}.blend -o //{{output_directory}} -F {{JPEG}} -f {{-2}}` - Render the animation of a specific scene, starting at frame 10 and ending at frame 500: `blender -b {{filename}}.blend -S {{scene_name}} -s {{10}} -e {{500}} -a` - Render an animation at a specific resolution, by passing a Python expression: `blender -b {{filename}}.blend --python-expr '{{import bpy; bpy.data.scenes[0].render.resolution_percentage = 25}}' -a` - Start an interactive Blender session in the terminal with a python console (do `import bpy` after starting): `blender -b --python-console`
