Web-based terminal

It's a Unix System! I know this!

WebAssembly Unix terminal built with 🦀Rust🦀

Features

• Essential Unix commands (sh, ls, cp, mv, cat, cowsay, etc)
• Basic Vi implementation
• Pipes and file redirect
• Variables and subshells
• File system via rust-vfs
• Basic scripting support (try sh example.sh)
• GNU Readline-like features (key bindings, history, tab-complete)
• ANSI escape code support, including some colors

Known bugs

• Running foo=bar echo ${foo} will print foo's old value
• [ cannot compare multiword values because of how variable substition works
• No emoji support in vi

Example

$ fortune -s | cowsay

Wow what a great fortune
