# Booting BoredOS
BoredOS uses the Limine bootloader, which provides a flexible way to configure the boot process and pass parameters to the kernel.
## Boot Parameters
You can modify system behavior at startup by passing specific boot flags.
### Verbose Boot (`-v`)
The `-v` flag enables the kernel console (`kconsole`) during the boot process. When enabled, the kernel will display detailed initialization logs on the screen. By default, this is often disabled in the included configuration for a cleaner "splash-only" boot experience.
#### Toggling Verbose Boot at Runtime
You can enable or disable the verbose boot log directly from the Limine boot menu without modifying the source files:
1. **Select Entry**: When the Limine boot menu appears, highlight the **BoredOS** entry.
2. **Edit**: Press `E` to enter the entry editor.
3. **Modify Flag**: Find the line containing `cmdline: -v`.
- To **Enable**: Remove the `#` character if the line is commented out (change `# cmdline: -v` to `cmdline: -v`).
- To **Disable**: Add a `# ` at the start of the line.
4. **Boot**: Press `F10` to boot using the modified parameters.
#### Persistent Configuration
To change the default behavior permanently, modify the `limine.conf` file in the repository root before building the ISO:
```conf
/BoredOS
protocol: limine
path: boot():/boredos.elf
cmdline: -v
```

# Using the Desktop
The BoredOS desktop environment is designed to be intuitive while providing powerful window management and icons for quick access to your files and applications.
## Window Management
BoredOS uses a stacking window manager (BoredWM) that allows you to overlap and organize multiple windows.
### Basic Actions
- **Focus**: Click anywhere on a window to bring it to the front and make it the active window.
- **Move**: Click and drag the **title bar** (the top bar of the window) to reposition it on the screen.
- **Close**: Click the red traffic light close button in the top-left corner of the window.
### System-wide Shortcuts
BoredOS includes several global shortcuts to help you manage your workflow:
- **`Ctrl + P`**: Take a screenshot. The image will be saved to `/root/Desktop` as `screenshot.jpg`.
- **`Shift + Ctrl + Space`**: Toggle **Lumos** search (see the [Lumos guide](lumos.md)).
## Desktop Icons
Your desktop represents the contents of the `/root/Desktop` directory.
- **Launching**: Double-click an icon to open the file or launch the application.
- **Snapping**: Icons automatically snap to a grid for a clean look. You can toggle "Snap to Grid" and "Auto Align" in the [Settings app](../launching_apps.md).
- **Context Menu**: Right-click on the desktop background to create new files, folders, or refresh the layout.
## The Bottom Dock
The dock at the bottom of the screen provides quick shortcuts to your most-used applications, with for example:
- **Files**: Browse the entire filesystem.
- **Terminal**: Access the command-line interface.
- **Calculator / Notepad / Grapher**: Essential productivity tools.

# Launching Applications
BoredOS provides several ways to launch applications and files, depending on your preferred workflow.
## 1. Using the File Explorer
The File Explorer is the primary way to navigate the filesystem and launch any `.elf` binary or associated document.
1. Open the **Explorer** from the dock or desktop.
2. Navigate to `/bin` for system applications or your own user folders.
3. **Double-click** any executable (`.elf`) to run it.
4. Standard files (like `.jpg` or `.txt`) will automatically open in their default viewer.
## 2. Desktop Shortcuts and Icons
Commonly used applications are placed directly on the desktop.
- Simply **Double-click** any icon on the desktop to launch it.
- You can also create desktop shortcuts by right-clicking on a file and selecting **"Create Shortcut"**.
## 3. Using Lumos (Global Search)
For the fastest access, use **Lumos** to search and launch by name:
1. Press **`Shift + Ctrl + Space`**.
2. Type the name of the app (e.g., "DOOM.elf").
3. Press **Enter** to launch.

# Lumos: System Search
**Lumos** is the powerful, system-wide search and launch assistant for BoredOS. It allows you to find applications, documents, and system files instantly without navigating through folders.
## Opening Lumos
To activate Lumos at any time, use the global keyboard shortcut:
**`Shift + Ctrl + Space`**
The Lumos search modal will appear in the center of your screen, ready for input.
## Features
- **Fuzzy Searching**: You don't need to type the exact name. Lumos uses fuzzy matching to find the most relevant results as you type.
- **Deep Indexing**: Lumos indexes files across the entire system.
- **Quick Launch**: Once you find what you're looking for, launching it is as simple as pressing `Enter`.
## Navigation
When the Lumos window is open:
- **Type**: Just start typing to filter results.
- **Arrow Keys (Up/Down)**: Move the selection highlight through the list of results.
- **Enter**: Launch the selected file or application.
- **Backspace**: Delete characters in your search query.
- **Escape**: Close Lumos and return to the desktop.

# Terminal & Command Line
The BoredOS Terminal provides a powerful command-line interface (CLI) for advanced users and developers. It supports standard Unix-like features and provides direct access to the kernel's system calls.
## The Shell
The default shell in BoredOS is a custom-built, lightweight command processor integrated into the Window Manager. It features:
- **ANSI Color Support**: Rich text output with colors and styles.
- **Command History**: Use the **Up** and **Down** arrow keys to navigate through your previous commands (up to 64 history entries).
- **Output Redirection**:
- `command > file`: Write output to a new file (or overwrite existing).
- `command >> file`: Append output to an existing file.
- **Piping**:
- `command1 | command2`: Pass the output of the first command as input to the second.
## Common Commands
Below are some of the most used commands available in `/bin`:
| Command | Description |
| :--- | :--- |
| `ls` | List files and directories in the current path. |
| `cd` | Change the current working directory. |
| `cat` | Display the contents of a file. |
| `ls` | List directory contents. |
| `rm` | Remove a file. |
| `mkdir` | Create a new directory. |
| `man` | View the manual for a specific command (e.g., `man ls`). |
| `sysfetch` | Display system and hardware information. |
