There was a mailing list for the unix re-implementation of rc by Byron Rakitzis, this includes many examples and general info.
Be careful however, there are a few significant syntatic differenctes between Byron's RC and Plan9's one, I am fairly sure these are detailed in an appendix at the end of Byron's paper (in the source package). info here. http://plan9.aichi-u.ac.jp/netlib/9fans/ http://rc-shell.slackmatic.org/ -Steve
