This project was my first experience doing a shell (a mini UNIX command interpreter) and managing process creation and synchronisation. I followed -> this subject <- rules to develop the shell.

• A promt that reprints itself when a command finishes execution;

• It executes any command found in the PATH provided by the environment and a few builtins:

  . cd

  . env

  . setenv

  . unsetenv

  . exit

  . 8 (that's an eight ball command)

  . lozenge (that is just a sweet personal touch to the shell)

• It manages the expansions $ and ˜

Clone this repositorie, after that, execute those commands:

1 | make all

2 | ./minishell

3 | test out the commands and enjoy this cozy shell!
