As beautiful as a shell

Summary:

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

To use minishell, clone the repository in the root of your project using one of the following commands:

git clone git@github.com:blueyaGIT/minishell.git

git clone https://github.com/blueyaGIT/minishell.git

gh repo clone blueyaGIT/minishell

This will create a directory called minishell/. Enter it with the command:

cd minishell

To compile the program, run:

make

This will generate the minishell executable.

Execute the program:

./minishell

This will run the minishell executable

• A Prompt just like Bash with working history
• History is saved during sessions
• Builtin Commands:
  • echo (with option -n)
  • cd (with relative & absolute path and - and ~)
  • pwd
  • export (with and without args, supports +=)
  • unset
  • env
  • exit
• execution of external Commands using the $PATH, as well as relative or absolute Paths
• Redirections: <, >, << & >>
• Pipes |: The output of each command in the pipeline is connected to the input of the next command via a pipe.
• Expansion:
  • handle env Variables starting with $
  • handle $?
• Support interactive and non-interactive mode
• Signal Handling for CRTl+C, CRTl+D & CRTl+\
