About

This project is about creating a simple shell. Yes, your own little bash. You will learn a lot about processes and file descriptors. Enjoy it!

Installation & Usage

Requirements

The only requirements are:

• GNU make
• Readline library
• GCC

Building the program

1. Open terminal and go HOME with cd ~, write this vim .zshrc and add this code:

function brew_install()

	cd /goinfre
	mkdir homebrew && curl -L https://github.com/Homebrew/brew/tarball/master | tar xz --strip 1 -C homebrew

Some Issues and How Did ve Fixed it

If we have solved it, it will appear as drawn, if we have not solved it, only the problem will be written.

• ✅ Firstly if u write only "unset" terminal will suppress segmentation fault to screen. The solution is simple, I will do it when I am available. We need to check if in the unset part, just it!
