# minishell
A simple shell.
This program was developed by [Yuta-Fujimoto](https://github.com/yuta-fujimoto) and [AuroraSloan](https://github.com/AuroraSloan)
## Features
### Simple commands
- Search and launch any executable in $PATH
### Builtin commands
|Command | Options / Arguments |
|----------|---------------------------|
|``echo`` | `-n` |
|``cd`` | relitvie or absolute path |
|``pwd`` | n/a |
|``export``| no options |
|``unset`` | no options |
|``env`` | n/a |
|``exit`` | no options |
### Expansion
- `'` inhibits all interpretions of a sequence of characters
- `"` inhibits all interpretation of a sequence of characters except for $
- Environment values expand to their values
- `$?` expands to the most recently executed foreground pipeline
### Redirection
- ``<`` redirects input
- ``>`` redirects output
- ``<<`` reads input from the current source until a linie containing only the delimiter is seen
- ``>>`` redirects output with append mode
### Piping
- The output of each command in the pipeline is connected via a pipe to the input of the next command
### Signals
- ``Ctrl-c`` prints a new prompt on a new line
- ``Ctrl-d`` exits the shell
- ``Ctrl-\`` does nothing
----
## Installation
```bash
git clone https://github.com/AuroraSloan/minishell.git
```
----
### Usage
First, create the executable with make
`make` - compiles the minishell executable
`make clean` - removes all object files
`make fclean` - removes all object files and the executable
`make re` - removes all object files and the executable before recompiling the program
In order to run the program, simply run the executable.
```bash
./minishell
```
To exit the program, you can use the builtin command ``exit`` or press ``Ctrl-d``.
