rc - a shell ============ This is rc, the Plan 9 shell, reimplemented for Unix by Byron Rakitzis. The original rc was designed and implemented by Tom Duff at Bell Labs. It has a small feature set similar to a traditional Bourne shell, but with a much cleaner and simpler syntax. Among other things, this makes rc much better than Bourne-compatible shells at handling filenames which contain spaces. Thus, writing rc scripts is less error-prone than writing sh scripts. This reimplementation of rc can be linked with GNU readline, BSD libedit, or similar line editing libraries, to make a pleasant interactive shell. See COPYING for copying information.

Installation ------------ rc is built and installed using the following commands: $ make # make install Please note, that the second command requires root privileges. By default, rc is installed using the prefix "/usr/local", so the full path of the executable will be "/usr/local/bin/rc". You can install rc into a directory of your choice by changing the second command to: # make PREFIX="/your/dir" install The EDIT make macro controls which line-editing library to use: null, edit, editline, readline, vrl, bestline. For example, to make rc use the readline library, you have to build it with the following command: $ make EDIT=readline All other build-time specific settings of rc can be found in the file config.h. Please check and change them, so that they fit your needs. If the file config.h does not already exist, then you have to create it with the following command: $ make config.h
