codecrafters-shell-go

This is a starting point for Go solutions to the "Build Your Own Shell" Challenge.

In this challenge, you'll build your own POSIX compliant shell that's capable of interpreting shell commands, running external programs and builtin commands like cd, pwd, echo and more. Along the way, you'll learn about shell command parsing, REPLs, builtin commands, and more.

Note: If you're viewing this repo on GitHub, head over to codecrafters.io to try the challenge.

Passing the first stage

The entry point for your shell implementation is in app/main.go. Study and uncomment the relevant code, and push your changes to pass the first stage:

git commit -am "pass 1st stage" # any msg
git push origin master

Time to move on to the next stage!

Stage 2 & beyond

Note: This section is for stages 2 and beyond.

1. Ensure you have go (1.25) installed locally
2. Run ./your_program.sh to run your program, which is implemented in app/main.go.
3. Commit your changes and run git push origin master to submit your solution to CodeCrafters. Test output will be streamed to your terminal.
