minishell
## Summary
> This project challenged us to make our own shell. It is basically a reduced version of the Bash shell (a humbly little version of that) written in C.
> It provides a simple and minimalistic command-line interface for users to interact with the operating system. Developed in pair with @0xEDU.
## Features
- Simple command-line interface
- Command history
- Built-in commands: cd, pwd, export, unset, env, exit, echo
- Command execution with arguments
- Multiple command execution with pipes: |
- Redirecting operators: <, >, >> and <<
- Environment variable expansion: $
- Signal handling: CTRL-C, CTRL-D
## Getting Started
### Prerequisites
To compile and run Minishell, you'll need a C compiler and the GNU Readline library. The following instructions assume you are using a Unix-based system, such as Linux or macOS.
### Compilation
1. Clone the repository:
```bash
git clone https://github.com/Guiribei/my_shell.git
```
2. Change to the repository directory:
```bash
cd my_shell
```
3. Compile the project using the provided Makefile:
```bash
make
```
### Running Minishell
After successful compilation, you can run Minishell by executing the generated binary:
```bash
./minishell
```
You will be greeted with a colored command prompt, where you can start entering commands.
```diff
+minishell:~$
```
## Example Usage
Here's a quick example of what you can do with Minishell:
```
minishell:~/home/user/my_shell$ echo "Hello, World!"
Hello, World!
minishell:~/home/user/my_shell$ ls
includes libft Makefile minishell objects sources
minishell:~/home/user/my_shell$ exit
```
### Limitations
Minishell is a reduced version of Bash, and as such, it does not support all features available in a full-featured shell. Some of the missing features include:
- Command separators as ; and &&
- Scripting capabilities
- Customization and extensibility
- Wildcards
