This C project from the 42school is the implementation of a not-at-all Posix compliant shell.

Features

• execution of simple commands (with absolute or relative path);
• builtins: cd, echo [-n], pwd, export, unset, env and exit;
• pipelines |, output redirections > >>, input redirection < and heredocument <<;
• list of commands with &&, ||, ; and parentheses () for priorities (no redirections, pipes or subshells involved);
• variables expansions within or without quotes, including $?;
• quoting with simple or double quotes : ' and ", including variables split;
• ctrl-L, ctrl-D and ctrl-C control keys binded;
• incremental history of commands;
• line edition including backspace, delete, home, end and arrow keys;
• custom prompt displaying user, host and working directory in colors;
• wildcards * working in current directory.

• input using termcaps;
• lexer using tokenizers;
• recursive-descent parser building an Abstract Syntax Tree.
