| Type | Unix shell |
The es shell is a command line interpreter developed by Byron Rakitzis and Paul Haahr, that uses a scripting language similar to the rc shell of the Plan 9 operating system. It is intended to provide a fully functional programming language as a Unix shell. The bulk of es' development occurred in the early 1990s. A paper on an early version of the es shell was presented at the Winter 1993 USENIX conference in San Diego.[1]
A patched version of es-0.9-beta1 which includes job control features, a precompiled binary, additional documentation, a basic emacs editing mode and other contributed programs is available: es-0.9-beta1job-control.tar.bz2
The Xs shell is a fork of es with bugfixes, code cleanup, better readline integration and syntax improvements. Kes is a fork of es compatible with Linux and Mac OS X.
