Converting RTF to plain text (OS X)

To convert an RTF file (or other formats) to plain text, printing to stdout, use

textutil -stdout -convert txt '/path/to/your/file.rtf'

I'm using this with GeekTool to convert a Sidenote note (a to-do list) to plain text so it can be displayed on the desktop.

Geeza Pro is a good font for text on the desktop at small sizes.
