# 42sh
42sh school project.
Mandatory part:
- Prompt without line edition.
- Builtins `cd`, `echo`, `exit`, `env`, `setenv`, `unsetenv` with there options.
- Executing simple commands with there parameters using `PATH`.
- Support for redirection `>`, `>>`, `<`and `|`.
- Logical operand `&&`and `||`.
- Separator `;`.
Optional feature (five of theses are mandatory to validate the project):
- Inhibitors `"`, `'`and `\`.
- Advanced redirections: aggregation of file output and heredoc `<<`.
- Globbing: `*`, `?`, `[]`, `{}`, etc.
- Backquotes \`.
- Subshell with operand `()`.
- Local variable and builtin `unset` and `export`.
- History with builtin `history`and `!` with options.
- Advanced line edition.
- File descriptors and builtin `read` with options.
- Dynamical autocompletion.
Optional feature highly appreciated:
- Job Control and builtins `job`, `fg`, `bg`and operand `&`.
- Shell Scripting.
