Project 2: Shell Builtins

Description

For this project we'll be adding commands to a simple shell.

The shell is already written, but you will choose five (5) shell builtins (or shell-adjacent) commands to rewrite into Go, and integrate into the Go shell.

There are many builtins or shell-adjacent commands to pick from: Bourne Shell Builtins, Bash Builtins, and Built-in csh and tcsh Commands.

Feel free to pick from sh, bash, csh, tcsh, ksh or zsh builtins... or if you have something else in mind, ping me and we'll work it out.

As an example, two shell builtins have already been added to the package builtins:

• cd
• env

Steps

1. Clone down the example input/output and skeleton main.go:

   git clone https://github.com/jh125486/CSCE4600

2. Copy the Project2 files to your own git project.

   1. In your go.mod, replace "jh125486" in the module line with your GitHub name, e.g.:
   • "module github.com/jh125486/CSCE4600" changes to "module github.com/CoolStudent123/CSCE4600"
   2. In the main.go, replace "jh125486" in the imports with your package path, e.g.:
   • "github.com/jh125486/CSCE4600/Project2/builtins" changes to "github.com/CoolStudent123/CSCE4600/Project2/builtins"

3. Start editing the main.go command switch (lines 57-64) and the package builtins with your chosen commands.
