This program is a collaboration between Stephanie @StephVibes and Henriette @Henrizz.
It is our submission to the 42 Berlin school project MINISHELL, about creating our own shell, with bash as behavioural reference.

Run the program by typing make and then ./minishell

You will be able to execute the following cases, among others:

• run system commands with path or without path and any possible flags (e.g. /usr/bin/ls or ls)
  
• run the following builtin commands:
  ◦ echo with option -n
  ◦ cd with a relative or absolute path, and with - and --
  ◦ pwd (without options)
  ◦ export (without options)
  ◦ unset (without options)
  ◦ env (without options or arguments)
  ◦ exit (without options)
  
• redirect input or output with <, >, <<, >> over one or several files or heredocs (heredocs being closed by the delimiter or CTRL+D or CTRL+C)
  
• run piped commands
  
• expand variables in the commands, filenames and heredoc input
  

Part of the bonus was the thorough expansion of nested quotes of types '"' and '''
Our shell does not support '&&' or '||'

ENJOY !
