42 Minishell Project 🐚

Minishell is our minimalist bash shell implementation coded entirely in C.

• Command execution, redirections (> >> << <), and pipes (|)
• Environment & Local Variables
• cd, echo, env, export, pwd, unset, and exit
• Graceful Signal Handling: Ctrl+C, Ctrl+\, and Ctrl+D
• Error Handling
• Robust Memory Management

Installation and Usage

1. SSH:

   git clone git@github.com:dimadem/minishell.git minishell
   cd minishell
   sudo apt update
   sudo apt install libreadline-dev
   make
   ./minishell
   

2. Valgrind output saved in valgrind_out.txt after:

   ulimit -n 1024 # necessary once only, to address 'file descriptor too high' error
   make valgrind

3. Please see documentation for this project under https://dimadem.github.io/minishell/

4. The project uses an Abstract Syntax Tree (AST) to recursively enforce the correct order of execution for commands. This ensures proper parsing and execution logic, even for complex pipelines and redirections.
