schemesh

Unix shell and Lisp REPL, fused together

Schemesh is an interactive shell scriptable in Lisp. It is primarily intended as a user-friendly Unix login shell, replacing bash, zsh, pdksh etc. As such, it supports interactive line editing, autocompletion, history and the familiar Unix shell syntax: it can start commands, including redirections, pipelines, job concatenation with ; && ||, groups surrounded by { }, subshells surrounded by [ ], and manage foreground/background jobs.
