The es shell is a command line interpreter developed by Byron Rakitzis and Paul Haahr, that uses a scripting language syntactically similar to the rc shell of the Plan 9 operating system[1], and was originally based on code from Byron Rakitzis's clone of rc for Unix.[2] It is intended to provide a fully functional programming language as a Unix shell.[3] The bulk of es development occurred in the early 1990s, after the shell was introduced at the Winter 1993 USENIX conference in San Diego.[4]

Current official releases appear to have ceased with the release of 0.9-beta1 in 1997[5], and standard es lacks some features compared to more popular shells such as zsh and bash [6], but unofficial development has been continued with job control and history patches and a more ambitious fork, Xs (including syntax changes and C++ code).
