Minishell

Minishell is a simple shell program written in C that emulates a basic command-line interface. It supports executing commands, handling built-in commands, managing environment variables, implementing redirections, handling pipes, and more. Please note that Minishell was tested only on macOS.

Features

Display a prompt with the current directory.
Command history support.
Search and launch the right executable based on the PATH variable or using a relative or absolute path.
Handle single quotes ('), preventing interpretation of env variables within the quoted sequence.
Handle double quotes (").
Implement input and output redirections using '<', '>', '>>', and '<<'.
Support command pipelines using the '|' character.
Expand environment variables (sequences starting with '$') to their values.
Handle special variables like '$?' to expand to the exit status of the most recently executed foreground pipeline.
Handle signals: ctrl-C, ctrl-D, and ctrl-\ with expected behaviors.
Implement built-in commands: echo, cd, pwd, export, unset, env, and exit.
