Rustyshell

This is a small project for me to play with to help me learn some Rust.

It probably would have been better to call the shell rush (RUsty SHell) — perhaps I’ll change it later!

The shell supports a couple of features only:

• Run commands

• List history…​ with the, unimaginatively named history built-in

• Re-execute a command from your history with !n — where n is the index shown in the output of history

• Change working directory with the cd built-in

Here’s some sample output:

** rustyshell, v0.0.1 **
rustyshell::> ls
Cargo.lock	Cargo.toml	src		target
rustyshell::> pwd
/Users/matt/dev/rust/rustyshell
rustyshell::> whoami
matt
rustyshell::> history
1. ls
2. pwd
3. whoami
rustyshell::> !1
Execute 'ls' [Y/n]
Cargo.lock	Cargo.toml	src		target
rustyshell::> exit
