GoShell 🐚

A small shell written in Go — because why not?

This started as a weekend project to figure out how shells actually work. I ended up building something that can run real commands, has some built-in features, and is honestly kinda fun to use.

Why I built it

I was curious about how shells handle input, spawn processes, and interact with the system. Writing it in Go made things super clean, and I learned a lot along the way. It’s not meant to replace your terminal — just something cool to hack on and learn from.

How to run it

If you’ve got Go installed, just do:

go run main.go

Boom. You're in the shell.

What it supports

I added support for a bunch of commands — some built-in, some passed to the system:

• exit, ping, pwd, ls, cd, echo
• mkdir, touch, rm, cat, clear, date
• curl, ip, vim

It’s got enough to feel usable, but not overloaded with stuff.

Things I might add later

• Piping (|) and redirection
• Command history (with arrow keys)
• Tab completion
• Maybe themes or aliases if I get fancy
