minishell

This project is about developing a simplified version of the bash shell.

Sections

Minishell project is divided into 4 distinct parts:

• Lexer: Takes the entered line as input and reads through the line word by word using white space as delimiters.
• Parser: Groups the different nodes together based on the tokens (i.e. |, <, >>, >>, >). Each group becomes a command.
• Expander: Takes variables, identified by $, and replaces them with their value from the environment variables.
• Executor: Is the one in charge of executing the final command.
