# rsh

Shell interpreter written in go, inspired by [Tom

Duff](https://en.wikipedia.org/wiki/Tom_Duff)'s simple shell (ssh.c).

rsh is capable of:

* simple commands

* file patterns (`?` and `*`)

* quoting ('...' and \c)

* continuation with `\` at end of line

* redirection (`>` and `<`)

* pipelines

* synchronous and asynchronous execution (`;` and `&`)

* conditional execution (`&&` and `||`)

* only built-ins are `cd`, `path` and `exit`

* nothing else

It is very much work in progress so random panics are expected.

It is _not_ ready for daily use just yet.

Grammar is roughly:

	cmd:	simple

	|	simple | cmd

	|	simple ; cmd

	|	simple & cmd

	|	simple && cmd

	|	simple || cmd

	simple:

	|	simple word

	|	simple < word

	|	simple > word

	|	simple < word1 > word2

	|	simple &

## TODO

* probably something else
